Preparing For Heavy Rain And Winds


A check list and some frequently asked questions:


1) Secure or store deck furniture.

This includes: Tables, umbrellas; anything that can be blown by strong winds and become a potentially damaging projectile

2) Automatic pool coversIf your pool is still open: During periods of heavy downpours, we recommend opening automatic covers so heavy rain can fill the pool and not your closed cover. Heavy rain on top of your cover (a foot or more) could damage it. 

We also recommend this because, should your area lose power, the cover will be “stuck” closed. A sump pump cannot keep up with this volume of rainfall- especially if power is out.

While using your cover pump to remove accumulated water, be sure to run pump discharge into skimmers with system running so water is filtered and added to pool beneath cover.  

If you have a “Grando” or similar style floating automatic pool cover that drains off into pool, your decision to leave it open or closed should be based on the risk of wind-blown branches or debris which could damage your cover.

Yes, your pool will get messy with blowing leaves. This is a preferrable outcome to expensive repairs of a damaged auto cover. Leaves and branches can be scooped and picked out of the pool afterwards.


3) If you can winterize your pool before the storm arrives, do it!


4) Water table issues: Pools located in areas where ground water can surge should NOT be pumped too low. It is almost always okay if your pool overflows! Consider the following:

Do not lower pool water level excessively to “make room” for heavy rains. There is a real risk of floating a swimming pool or buckling the shell if pool water levels are too low during prolonged periods of heavy rains where water tables surge. Leave pool at normal winter water levels (between bottom of tile and 11″ below bottom of tile.) 

The risk is greater with pools in flood-prone areas including properties adjacent to the LI Sound. An overflowing pool is preferable to an opened hydrostatic relief valve (which requires a diver to re-set). Hydrostat valves can open and become stuck open when water table surges up and above water level inside pool.

The exception to this rule is the odd situation where an overflowing pool creates other problems that must be avoided (you know who you are).


Q: What about pool chemicals?

A: Normal levels pool chemicals are diluted during heavy rains and will  NOT cause damage to grass or gardens this time of year. Chlorine dissipates rapidly on the ground. Don’t worry about pool chemicals hurting anything should your pool overflow during a heavy downpour.


5) If you are a Glen Gate Client, we will reach out to those in hard hit areas. If you are not a client and need assistance please feel free to inquire about our services by contacting our office at 203 762-2000.  

Our Pool and Property Care teams specialize in storm clean-up.


6) If you have a significant amount of landscape soil wash into your pool- call us to assess the situation. It may be we can save the water. In some heavy wash-in situations we may advise draining and cleaning out the pool.


7) For those of you on the coast-  Let your pool fill. Your pool structure is safest when full should a wave come inland and reach your property; or there be severe flood tides.

For now, we hope you and your property are safe and sound!

Opening Your Pool

Bob Russell | May 28, 2015 in Uncategorized | Comments (0)

BergOpening up a swimming pool is not as hard as some believe.

If you close it right, it should open relatively quickly and easy- almost always.

For those times a repair is required, it is always best to be working with licensed, experienced professionals.

A pool owner should interview and select a service provider as they would an employee for a very important job position in their company. The best and most productive employees usually cost a bit more annually but they more than justify the extra costs and make your life far more enjoyable.

Life, like the Summer, is short. Spend it wisely and enjoy your pool!

High Tech Pool And Spa Stuff- Sanitization- Part 2

Ultra Violet

Since the advent of the residential swimming pool there has been a quest for the perfect bather experience.

In the 50′s and 60′s pool owners would employ liquid chlorine (bleach) to minimize algae growth and prevent water-bourn ailments such as ear infections. During this time period ear infections became so associated with swimming pools the term “swimming pool ear” was coined to describe the painful affliction caused by bacteria breeding in unsanitary pools.

By the 60′s and 70′s we had made good progress in the area of pools and spa sanitization and our focus moved towards bather comfort. During this era, irritating odors and red eyes marked the recreational swimming experience. It was during this time “Bromine” was introduced as an alternative- this did in fact lessen, but not eliminate, the adverse effects of what we now understand to be a very treatable sanitization problem- caused by ammonia.

The source of ammonia, as it turns out, was the bathers. Ammonia readily forms a compound with chlorine- it is this compound (often referred to as “chloramines”) that is responsible for irritation of swimmer mucous membranes. If you’ve ever made the mistake of mixing ammonia and bleach together while cleaning your house, you’ll probably never forget it.

Unfortunately, many still blame chlorine for the irritation we now know to be caused by ammonia introduced by bathers. “Free Chlorine” is virtually odorless at levels that are more than adequate to maintain healthy water. As a comparison, the drinking water standard allows 4.0 ppm chlorine; the standard for pool sanitization is 3.0 ppm chlorine.

Ammonia- the real culprit for eye irritation, is easily oxidized and gassed off with appropriate treatments. Chlorine remains the preferred sanitizer for a host of reasons, not the least of which is: it is the most environmentally compatible sanitizer, it is also the least costly.

The use of ozone generators and non-chlorine shock has all but eradicated the red eyes and obnoxious odors caused when ammonia meets chlorine. End of problem… but wait… what about our quest for the perfect bather experience?

UV (Ultraviolet) light is making a resurgence in today’s marketplace- a marketplace that continues to demand the ultimate bather experience.

While a salt/chlorine generator and ozone combination makes for delightful water to bathe in- the demand for “perfect water” (which generally means LESS CHEMICALS) is still heard from the most discriminating pool and spa owners.

This is where UV sanitization is becoming increasingly popular.

A quick description UV and it’s applications:

UV can not be used in place of chlorine, but, it can reduce the “chlorine demand” by reducing the volume of pathogens- specifically the ability of water-bourn pathogens to reproduce.

Remember a point I made in a previous article- I compared the swimming pool or spa to a “Petrie Dish…” It’s actually a very good comparison. There must be a sanitizer present (i.e. an agent that kills bacteria, viruses and plant life) to maintain water that will not make bathers sick or grow algae.

UV is making a come-back because it reduces the amount of sanitizer required to maintain sanitary conditions for bathers. UV alters the DNA in live organisms so they cannot reproduce- thus reducing the demand for more chlorine. It must be noted here that UV does not kill bacteria or viruses, but it has been shown effective in reducing their ability to reproduce. Recall the Petrie Dish experiment- if you want to grow a particular bacteria, virus, fungus, or algae FAST, place it in a sterile environment with food. Live things reproduce exponentially unless they are checked by an agent (e.g. Chlorine)- or altered so they cannot reproduce, this is what UV light does.

UV is used extensively- it is popular in water features and ponds that host aquatic life- since there is no sanitizing agent like chlorine in a pond, UV helps control unwanted growth of water-bourn pathogens that can adversely impact plants and fish.

If you are one of those looking for the perfect bather experience, consider adding UV to your sanitizing system. It will reduce the chlorine demand.

If you share our passion for this subject, you are on a quest for the ultimate bather experience! Contact us at Glen Gate Company and one of our experts will be happy to help you find that perfect bather experience.


Below is an excerpt from a Wikipedia post:

Sterilization and disinfection

“…Ultraviolet lamps are used to sterilize workspaces and tools used in biology laboratories and medical facilities. Commercially available low-pressure mercury-vapor lamps emit about 86% of their light at 254 nanometers (nm), which is near one of the peaks of the germicidal effectiveness curve. UV light at these germicidal wavelengths damage a microorganism’s DNA so that it cannot reproduce, making it harmless, (even though the organism may not be killed). Since microorganisms can be shielded from ultraviolet light in small cracks and other shaded areas, these lamps are used only as a supplement to other sterilization techniques.

Disinfection using UV radiation is commonly used in wastewater treatment applications and is finding an increased usage in municipal drinking water treatment. Many bottlers of spring water use UV disinfection equipment to sterilize their water…”





Pool Restoration

Pool Restoration

Here are some important considerations for those deciding to renovate or restore a swimming pool in Connecticut.

I took this first picture during a pool inspection around 2008. Note the hairline crack just above tile and beneath coping stones. I told the pool owner, “…you will begin to lose tile in this area in 2-3  years.

The second picture was taken in 2010. Same pool, same area.

PoolInspectionShots041508 044










Did you know that tile problems are almost always a symptom of coping problems?

Coping problems can be related to expansion joint problems (or lack of expansion joint).

Or, they can simply be normal pool maintenance because we live in the North east and have harsh Winters.

The point of my anecdote: When you decide it is time to restore your swimming pool to it’s original glory, be sure to find an experienced (and licensed, by the way) expert who will not only attempt to sell you a tile job; or re-set coping stones and re-surface your pool, find someone who can spot why something failed; someone who understands how to repair in such a way that you don’t have to do this again for a long time.

In my experience as a pool inspector, the #1 reason for coping/ tile problems is inadequate expansion joints. The #2 cause is inadequate drainage around pool.

#3 is the fact you own a pool in New England! Seasonal changes are just rough on masonry!


Root Causes and Codes

The second and final point I’d like to make in this post is this: once you have an expert who understands root causes of problems and can offer long-lasting solutions, be sure your pool repairs are done in accordance with local and state codes. This is not just good advice, it is the law:

  1. Pool renovation and restoration work must be done by licensed companies using licensed employees.
  2. Current pool building standards apply to renovation or restoration work.

One example of this is the so-called, “anti-entrapment codes.”

When re-surfacing a swimming pool in Connecticut, the pool is to be brought into current building and safety standards. There may be some variation in interpretation of the building code from town to town, but essentially, every pool that is having any kind of permanent changes made to the circulation system must be brought to current building standards- this includes preparation work for re-surfacing!

These standards include splitting floor suction outlets 3′ apart AND employing a third “dummy drain” for water table management.

This is a picture of us doing just that on a recent pool restoration project.










We’ll continue on the subject in my next post.

Thank you for reading.

Enjoy the Summer!



Again… “Is My Pool Safe?”

It always shakes us up a bit to think that a swimming pool- a symbol of recreation, laughter and family summer fun- could be otherwise. The recent news of entrapment and near drowning in a swimming pool has again shaken the confidence of pool owners -or those who might consider owning a pool.
I have reviewed this issue before (see previous post).
The Association of Pool and Spa Professionals (APSP) has released the statement below. For those of us here in Connecticut- we’ve been down this road before.
At Glen Gate- where safety is engineered into our design and woven into our service- we cannot imagine a swimming pool that is NOT safe. I must admit, I get mad over this issue. For us at Glen Gate, it is not only unacceptable to build or service a pool with entrapment risks, it is criminal.
When I do pool inspections for Real Estate Agents and see loose or missing suction outlet covers or other missing layers of protection I take the opportunity to educate and advise, and, I try hard to hide my anger. But, I have no problem advising a would-be Buyer or Real Estate Agent to find another service provider who gets it right.
My advice to all pool owners: 1) Find a licensed service provider! 2) Interview your service provider well; in CT,  ask them if they are licensed!
Safety and recreational swimming go hand in hand- it is basic and foundational!
The details of this incident are not yet out so I should temper my comments: I have found that most of the suction outlet problems I see in the field during inspections, are on pools or spas where the Homeowner is handling their own service. I do believe the pool industry has greatly improved in this area! While it’s not 100% yet, I think the facts will emerge- we’re dealing with another layer of “service providers” here, namely: unlicensed service providers, homeowners, caretakers and uncle Fred.
As far as I can see in Connecticut and New York, MOST service providers have gotten this issue right!
Thanks for reading.
Below is the APSP release.

Dear Member,
Yesterday a national recording artist’s son nearly drowned in a residential pool. While the specifics of the incident aren’t known at this time, there is some indication it was a limb entrapment due to a missing drain cover.
This serves as an important reminder about safety and entrapment avoidance in pools and spas, particularly residential pools and spas built prior to the enactment of the VGB and the
ANSI/APSP-7 Standard . This also creates a unique opportunity for you, the pool and spa professional, to reach out to your customers (as well as potential new service customers) and even local media to bring these pools into compliance with the ANSI-7 Standard, which was developed to eliminate this very hazard. The design recommendations and construction practices in this Standard are based upon sound engineering principles, research, and field experience. The Standard is referenced in the 2009 International Residential Code, the 2009 International Building Code, the 2012 International Swimming Pool and Spa Code (ISPSC), and has been adopted by many state and local authorities.
The ANSI/APSP-7 Standard allows for several options with regard to existing pools, including drain disablement or converting the suction outlet to a return inlet. Where suction outlets (drains) are used, they should be equipped with fittings (covers) that are certified in compliance with the ANSI/APSP-16 Standard for Suction Fittings for Use in Swimming Pools, Wading Pools, Spas, and Hot Tubs as referenced by the federal Virginia Graeme Baker Pool & Spa Safety Act, along with one or more of the additional measures provided in the ANSI/APSP Standard (multiple main drain system, gravity flow system, engineered vent system or properly listed SVRS).
As you are aware, residential pools and spas are not required to meet these safety requirements unless specified in state or local code. Hence you should not make the statement that the pool must be upgraded because of federal law. You can point out, however, that public pools throughout the country are required to install new suction fittings and other necessary means, and that as a residential pool owner, they can get the same level of protection for their family and friends. Any pool with a missing or broken drain cover is at the highest risk for an entrapment incident.
Please also contact your customers and your local media to emphasize these important safety tips:
  • Never enter a pool or spa that has a loose, broken, or missing suction fitting or drain cover.
  • Immediately notify the pool or spa owner/operator if you find a loose, broken or missing drain cover.
  • Never play or swim near drains or suction fittings.
  • Contact an APSP pool and spa professional to repair and bring the pool or spa into compliance with the ANSI/APSP-7 Standard.
That is your consumer message.
Feel free to refer your customers and others to or for general drain cover safety information and tips. In addition, you can purchase brochures on Entrapment Avoidance Guidelines or copies of the ANSI/APSP-7 Standard from . Please offer your services to help replace and upgrade pool drain covers and do an inspection so that pools and spas can be enjoyed safely. It’s just good business.

Managing Pool Water In Extreme Weather- Some Important Things To Know

2013- A Summer of Extreme Sanitizer Demand-


Q: “How did I wind up with algae in my pool when my chlorine levels have been perfect!”

A: Chlorine demand is a term service providers use to describe a pool’s specific sanitizer requirements. It is a term we must consider in extreme weather- chlorine demand is a concept that helps us prevent pool water going from clean to green- something that can occur in a very short time during extreme weather conditions.

As the term implies, sanitizer requirements will vary. We tend to adjust our sanitizer feeder equipment to “normal” and forget about it. The purpose of this post is to help you understand when “normal” sanitizer settings will not maintain sanitary water- under certain extreme conditions a pool’s sanitizer level can drop from “ideal” to zero in an hour.

So far, this summer has included some of the most difficult “chlorine demand” challenges I have ever seen. The following events are examples of things that can dramatically change chlorine demand; my goal is to help you recognize when something is happening and prevent problems:

  1. Hot weather
  2. Heavy rain
  3. Wash-in: Heavy rainfall shedding off lawns and gardens can contaminate pool water with organic matter and fertilizers.
  4. Heavy bather load- such as one might see at a holiday party that features swimming.

The Perfect Storm: This summer has included some long periods of hot weather: we have experienced frequent heavy thunderstorms with local torrential rainfall; add to all this a holiday party around the pool and the “normal” sanitizer levels are overwhelmed. Once sanitizer levels drop to zero a pool water is no longer sanitary for bathing- under these conditions water can cloud quickly and develop significant algae problems- often clouding within 24 hours. Pool Owners should also realize that pool water doesn’t cloud immediately once sanitizer hits “zero”-  it is during this period that water- even though still clear,  should be considered a potential health concern.

One fairly common health issue associated with swimming in pool water without proper levels of sanitizer is an ear infection- nicknamed “swimmers ear.” Such health issues are easily avoided if you understand extreme “chlorine demand” events and conditions and take precautions.

Recognize “Chlorine Demand” and Make Adjustments: Here are some things you can do to prevent losing the use of your pool for a week (or longer)- this is about the length of time it can take to recover and clean up from an algae outbreak or clouded water:

  1. Test water more frequently as chlorine demand conditions rise. You will “see” your sanitizer disappearing when you test and be able to make some good decisions before water clouds. You don’t have to be a certified water chemist to know the condition and quality of your pool water. Consider purchasing some good quality dip strips- this 5-second test is easy and gives you early warning to head off cloudy water and algae before it happens.
  2. Inform your service provider if you are planning a party. There are preventive things that can be done to handle the increase in bathers. It may be as simple as adjusting sanitizer feeder upwards and monitoring levels periodically. Normally a service provider comes weekly and balances the water and sanitizer levels. The point of this post is to help you recognize events or conditions that occur between visits that may be having a big impact on the water.
  3. Recognize when a heavy downpour may have introduced garden or lawn material into your pool- Fertilizer not only ties up pool sanitizer but at certain levels can render it ineffective! We will discuss how to remove Phosphates and Nitrates from pool water in another post; but you should be aware of any wash-ins and inform your service provider if this happens.
  4. Prevention is far easier- Preventing an outbreak of algae or clouded water is far easier and less costly than treating it. Clearing a cloudy pool or killing an algae bloom can be very expensive not to mention the disappointment of not being able to use the pool. Green water is probably the #1 or #2 reason why pool service providers are fired. The other reason being a slow response time. When sanitizer levels “crash” and water begins to cloud or algae has gained a foothold- time is critical.

In our upcoming blogs we’ll discuss some of the specific challenges presented by automatic pool covers and address bather issues such as sensitivity to chlorine or bromine.


Your Pool Is A Giant Petrie Dish! (and other revelations to help you through hot weather…)

Bob Russell | June 1, 2013 in Uncategorized | Comments (0)


The purpose of your pool’s “sanitizer” is to keep your pool sanitary. Another way of putting this: Sterile. Void of microscopic life. Safe for swimmers; AND, pleasant to be in!

Yes, you can have it all!

Plant life OR animal life should NOT be able to live or multiply in a pool. An unsanitary pool is both unhealthy to be in and usually unpleasant to look at.

It amazes me how many times I am asked about “chlorine-free” pools or even “sanitizer-free…” I simply know of none. Your pool and spa are not like your local stream, pond or lake- these “ecosystems” have a natural balance.
Your pool or spa is more like a petrie dish- a sterile environment with available food. Add a life form to a petrie dish and we know what happens, and fast. Your sanitizer keeps things “sterile.”

What MOST pool owners are looking for when they speak of “chlorine-free” or “alternative sanitizer” is a swimming experience that is lovely to all their senses, safe for the children; and of course, okay for the family dog to drink from.
This is a pool that is both balanced AND sanitary.

If your eyes are irritated- your chemistry is NOT right. Don’t throw out the chlorine! Balance the pool properly! Oxidize the ammonia!

We will address this in more detail in a future blog.

Perhaps, you just need to find a service firm that knows how to provide water that is delightful to be in.

If you would like a better experience in the water, we’d be happy to help.

Snow And More Snow!

Tags: , , ,

It’s been a snowy and rainy winter.

What can we expect when we open our pools in a couple months?

Here is a short list of general things to check out after a snowy/ rainy winter:

Check for winter cover damage. Heavy snow can pull out wall anchors; cause sharp coping to rip through cover; heavy snow on a winter cover can pull deck anchors and deck stones towards pool causing related masonry damage.

Check heaters for mouse damage- during periods of deep snow, mice move into heaters- more than usual.

Water chemistry- heavy snow and rains means your water chemistry has changed. Of primary concern is:

a) Sanitizer levels- these must be maintained to keep water clear and algae-free until opening day!

b) Calcium Hardness- rain water contains about 0 ppm calcium. After about 18″ – 36″ of rain between September and May, a pool’s Calcium Hardness has been diluted making the water “softer” and more aggressive towards plaster finish. Water left in this state for too long will cause finish problems.

For more details on these and related issues we recommend you consult with an experienced and licensed pool service professional.

If you are interested in our pool services, please contact us!

Meanwhile, Memorial Day Weekend is only 12 weeks away!

Preparing For Sandy

Preparing For Sandy

Seems like only a short while ago we were preparing for and cleaning up after Irene.

As a Pool Owner, here are some things you should know in a short check list format:

1) Secure deck furniture.

2) Automatic pool covers- Sandy is being called a “Superstorm” because she is merging with a winter storm as she chugs up our coast. This means a LOT of rainfall and flooding over a few days.

If your pool is still open, we recommend opening automatic covers so heavy rain can fill the pool and not your closed cover which could become severely damaged.

We also recommend this because, should your area lose power, the cover will be “stuck” closed. A sump pump cannot keep up with this volume of rainfall- especially if power is out.

(If you have a Grando style automatic pool cover which drains off into pool, your decision to leave it open or closed should be based on the risk of wind-blown branches or debris which could damage your cover.)

Yes, your pool will get messy and filled with leaves. This is a preferrable outcome to a severely damaged auto cover. Leaves and branches can be scooped and picked out of the pool afterwards.

3) If you can winterize your pool before the storm arrives, do it!

4) Water table issues: Pools located in areas where ground water can surge should NOT be pumped too low. It is not the end of the world if your pool overflows! Consider the following:

An overflowing pool is preferrable to an opened hydrostatic relief valve (which requires a diver to re-set). Hydrostat valves can pop and become stuck open when water table surges up and above water level inside pool. It’s just not a good idea to remove large amounts of water to “make room” for the heavy rains. You are putting your pool at risk.

Normal levels of winter pool chemicals are diluted during heavy rains and will  NOT cause damage to grass or gardens this time of year. Chlorine dissipates rapidly on the ground. Don’t worry about your pool over flowing during heavy downpour.

There is a real risk of floating a swimming pool or buckling the shell if it is left empty or partially empty. Leave pool at normal winter water levels (between bottom of tile and no lower than 11″ below bottom of tile.)

5) Contact your pool service professional for special situations or if you are unclear what to do.

6) For downed trees and property damage- please feel free to contact us if you are in our area.

Our service team specializes in storm clean-up. Rest assured we will keep an eye on things.

If you have a significant amount of landscape soil wash into your pool- call us to assess the situation. It may be we can save the water. In some heavy wash-in situations we will need to drain and clean out the pool.

For those of you on the coast- just let your pool fill up as rains increase. Your pool structure is safest when full should a wave come ashore or there be severe high tides.

For now, we pray our customers are safe and their homes protected from trees, high winds and floods.

Call if you need anything!

Pools And Heat Waves

Bob Russell | July 9, 2012 in Equipment maintenance,Pool,Pool chemicals,Pool Service,Uncategorized | Comments (0)

Heat Waves:

Every pool owner should understand two basic concepts about their pool during a heat wave:

1) Chlorine demand (or which ever sanitizer you are using)


2) The Petrie Dish 

Chlorine Demand is basically the understanding that it will take more chlorine to maintain a sanitary and clear pool under certain conditions. Chlorine demand increases during a heat wave because the things that “spend” chlorine tend to increase- these include: increased bather load; heavy thunder showers (including wash-ins); higher temperatures.

The second concept of the Petrie Dish helps the pool owner understand and visualize that without a sanitizing agent present in the water, algae or micro-organisms can grow very fast.

In the “perfect storm” of heavy bather load, thunder storm and high temperatures a pool can go from the ideal of 3.0 ppm chlorine to zero in a day. Generally a chlorine feeder cannot recover to 3.0 ppm by the time algae or micro-organisms have already started to multiply. Once plant and animal life has been established in a swimming pool, the chlorine demand can double or triple quickly. Unless you intervene, you will have a real problem and it all can happen in 24-36 hours.

Here’s what you can do:

  1. First, understand these two concepts. Awareness that something is happening before the pool is green, or someone gets an ear infection is best.
  2. Adjust chemical feeders to handle an increase in bathers.
  3. Careful with use of time clocks! I see this all the time- a pool owner trying to save $100. on their monthly electric bill winds up spending $500. to kill algae that has gotten out of hand. Chemical feeders are only adding sanitizer to pool while pump is running.
  4. Check pool water after a heavy storm or a pool party. This, more than anything, will help you understand chlorine demand and keep you aware when you need to do something between normal weekly service visits.
