Is my pool/spa safe?

I enjoy writing about the joy and recreational benefits of owning a pool or spa. When it comes to safety, things get very sober and serious for pool and spa Owners and those in the business.

In the last decade there have been several changes to standards and codes in the pool and spa industry.  The question I am asked most frequently is: “Is my pool or spa safe?”

Today’s safety codes are complex. Pools and spas are also complex. Most pool and spa Owners are bombarded with media hype, marketing gimmicks and general misinformation. I’d like to help. Here are the basic things I look for while inspecting a pool or spa. 

 1) Suction Outlet Covers: Floor and wall drain covers should be in place and secured by stainless steel screws. Residential pools and spas built since 2003-2004 are required to have two suction outlets that are spaced 3 feet apart.

2) Anti-entrapment Covers- In December of 2008, all [existing] commercial pools were required to install specially designed “anti-entrapment” suction outlet covers. Residential pools were to have existing covers replaced when they failed, or at the discretion of the homeowner. Note: The new covers are designed to prevent an object (such as a human body) from creating a seal over a suction outlet; they are also designed to prevent hair entanglement. As expected, these new covers are much more expensive than the old style; they are also made of extraordinarily strong material- unlike the older covers which are relatively easy to break.

Should you replace your spa or pool floor suction covers now?

That’s a good question to ask your service professional!

Some floor suction outlets (e.g. such as the single suction outlet pictured above) are more of a risk than others- it depends on how the pool or spa is plumbed.

The first and most important “layer of safety” is the most obvious: make sure the suction outlet covers are in place and secured.

Spa pictured above is fitted with an approved anti-entrapment cover.

3) SVRS Or, Vacuum Release System- A vacuum release system is an additional layer of safety that became law in 2005  for new residential swimming pools or spas

Vacuum release units (SVRS) vary in shape and size but are all designed to do the same basic thing: release an object that has made a seal over a suction outlet. 

Some ask, “…how can people get stuck on a main drain?” The answer requires a discussion of physics but in short, there can be tremendous force at a suction port that has been sealed. A one horsepower pump (for instance) has enough force to trap a grown man and hold him fast. Some drowning accidents have in fact happened in this way.

Pictured above is a common mechanical SVRS installed on suction-side of pump.

Is your pool or spa equipped with an SVRS?

Is it operational?

These are questions to ask your service professional!

 

Summary:

When inspecting your pool or spa, look for the following  “layers of protection”:

1)      Secured and approved anti-entrapment suction outlet covers. This is the most important layer of safety!

2)      Dual suction outlets - pools built after 2003-2004. (A second outlet can be added to existing pools.)

3)      SVRS system (vacuum release) - required in pools built after April 2005. SVRS systems can be added onto any pool for an additional layer of [anti-entrapment] protection.
