Missing Suction Covers in Foot Well...Safety First

[CanadianSpaTech]

I see this all the time. Missing Suction/pump return covers. If you have one that is broken or missing it is important to fix/replace ASAP. These covers provide a critically important safety feature. If you ever put your hand over a missing cover with the pump running in high speed it will suck your hand in and hurt. They were mandated years ago after a young girl got her hair sucked in and kept her under water with sad result.

The pic below is from a job I just worked on where the customer was just topping up his spa with a bit of water. Dropped his expandable garden hose in and turned the tap on. Within a split second it was sucked into the missing suction opening and made it's way from one side of the tub through the plumbing past a couple of 90 degrees elbows and a Tee fitting into the face of the pump. The impeller twisted it up 1,000 times. It actually sucked it in not from the fill end with the brass fitting but in the middle part of the hose. The brass fitting part stayed in the foot well. I can't hardly believe how many times I had to untwist the hose at the pump wet end, end before I could try and pull it back through and it was still twisted up inside the plumbing. Had to get at it by removing a second suction cover see on the right and pull it through that one first then cut it and pull it through where it got sucked in. It was a $250 mistake for the garden hose but the customer had young children using the spa and it could easily have cost a life over a $20 part and 2 minute fix.

FYI...those expandable hoses can stretch out for a mile.. or 2... lol

That would be Virginia Graeme Baker, namesake of the VGB act, later renamed the pool and spa safety act, which regulates protections from entrapment and evisceration (yes, that means sucking out your intestines when you sit on a suction at the bottom of the pool) on public pools and spas, as well as new private pool and spa construction in the US. Old private pools and spas are unregulated, and usually unsafe.

Thank you @CanadianSpaTech for bringing up this important topic. ⭐ Gold star for YOU my friend.

Maybe some our other knowledgeable industry contributors, like @waterbear, @jimmythegreek, @Pool Clown, would like to add to this thread with their knowledge and experiences.

This thread, or one like it, should be a sticky in every forum.

Only thing I will add is that ALL pool owners should upgrade their drain covers and suction inlets in pools and spas IMMEDIATELY if they have not already done so.

I am pinning this topic because it's an important one!

WARNING: DO NOT USE SPAS OR HOT TUBS UNLESS ALL SUCTION GUARDS ARE VGB COMPLIANT AND INSTALLED TO PREVENT BODY AND HAIR ENTRAPMENT. • Risk of drowning or injury. The suction fittings in this hot tub are sized to match the specific water flow created by the pump. Should the need arise to replace the suction fittings or the pump, be sure the flow rates are compatible and the replacement cover is VGB compliant. (Virginia Graeme Baker Pool and Spa Safety Act) Never operate hot tub if the suction fittings are broken or missing. Never replace a suction fitting with one which is not VGB compliant or rated less than the flow rate marked on the original suction fitting.

100% agree on VGB covers on every suction point, pool or spa doesnt matter. Even older pools with single main drains can benefit from a VGB cover. Things happen in a nano second in a pool or spa, be safe not sorry you didnt 

[cranbiz]

Just stop it. 

The retrofit cover might be VGB compliant but it's not VGB compliant without the associated plumbing.

You are making your spa safer with the new cover, it's still not fully VGB compliant. That's his point.

As far as Master Spa is concerned, I won't get into that.

[waterbear]

Enough all of you. I am going to hide these argumentative and inaccurate posts but for the record I will say that RDspaguy and Cranbiz are correct in this one.

I shudder when I see single source suction on a bayonet filter. That to me is a situation waiting to be had.

VGB are now being used on single suction pump circuits. Don't like it at all, but it may have un intended consequences in flow design. I would rather see suction head split between multiple points any day.

Well, this discussion is enlightening.... Thanks.

We purchased ourselves a 30-year-old Crown Nemco spa, "cheap"...

So far it's been an education, but I don't quite regret it (yet!)

This safety discussion is a good 'reality check', I do appreciate the shocking descriptions, awful as they are.

Is it likely that the suction cover on this old tub is VGB compliant? When did that standard go into effect? Our drain is on the side at the base of the foot-well, so at least it can't be sat upon.

The suction plumbing has a wye near the drain, which also goes to the in-pool filter, which then takes some of the suction that the pump creates, however I don't think it's much, the filter only has a 1" pipe feeding it. 

Thanks.

I replaced all 6 of mine as soon as I noticed them degrading.

Hello, I'm trying to figure out how to remove this suction cover, but no luck.  It won't budge.  I'm obviously missing something and don't want to break it.  Any ideas on how to remove this cover.  I have a bunch of mold I would like to clean from it.  Please any advise would help.  Thanks.

First time owners of a hot tub that came with a house we purchased. I now understand the importance of updating and replacing missing/broken suction covers. I have been unable to find replacement covers for our D1 Amore Bay (2008?) and am now afraid to use the hot tub! Hoping @CanadianSpaTech @waterbear @jimmythegreek or others can help suggest a solution. Can I purchase larger covers and attach them with screws to make the hot tub safe? I appreciate any recommendations. Attaching photo of an old cover.

Not sure if this will help but you might want to contact HTP of America and give them all your measurements and see what they recommend as what you have is likely discontinued. 

Including better/more photos might help us come up with a solution. Photo of the footwell with the cover removed so we can see what is there to attach to. Does the round center cap come off of the suction cover with a screw behind?

Happy you are addressing this issue. It is so important to have it working properly to prevent a heart breaking situation.
