• ANSI/APSP – 2011
• VGBA-2019 (ANSI/APSP/ICC – 2017)
Why are there so many certification marks?
The development of the applicable Standard allowed for various markings over time. All are acceptable.
The VGB-2008 and ANSI/APSP2011 are different in name only. ANSI/ APSP/ICC –16 2017 calls for the “VGBA-2019” mark. Short and easy to recognize.
Does the new standard require public pools to be retroactively updated with these new drain covers, even before they expire?
No.As long as the existing drain cover is compliant, was installed according to the manufacturer’s instructions, and is in good condition (not broken or loose), it may remain in use until its expiration date. If any cover is broken, loose or missing, the pool is NOT compliant and must be closed until proper repair/ replacement is made.
What about spare drain covers that are still in the manufacturer’s bag or box?
All prior models with the above markings may still be purchased and installed.
Why can’t I buy a drain cover that doesn’t stick up from the floor so much? My cleaner keeps getting stuck!
The domed or raised shape is necessary to prevent body entrapment (a body forming a seal over the cover), one of the leading causes of suction entrapments before the 2007 VGB Act.
Many models are available for most size drains.
Ask your industry professional to help you select one best suited to your overall needs.
My new drain cover came with a riser ring and the cover fits the existing sump without using it.
Is it okay to install the drain cover without the riser ring?
No! All covers must be installed as instructed. If the instructions require the use of the ring, then it is essential to prevent body entrapment.
They should never be removed.
Why are some drain covers flat and flush mount while other are not?
Larger drain covers that have been certified as unblockable can be flat.
The federal VGB Act allows the use a single unblockable drain, as an alternative to multiple smaller drains.
Some state codes, however, still require multiple drains in all pools.
What is “sump depth” and why does it matter since it is under a certified drain cover anyway?
The word “sump” refers to the space between any cover and the suction piping supplying water to the pump.
As water passes through the cover, headed for the suction pipe opening, turbulence is created and when strong enough it will tangle and twist hair.
This has the potential to lock it in and around the drain cover.
Turbulence, and suction power, become more extreme as the flow increases and at some point, ALL drain covers will tangle hair. This is one reason why drain covers have a flow rating that must never be exceeded.
The the drain cover is missing, is it okay to swim if the pump is turned off?
NO!
The open pipe creates a
DANGEROUS risk of limb entrapment.
An arm or leg can get stuck in the pipe. This has happened, especially with children.
