During a pool replastering this Spring, the hydrostatic relief plug was removed, but never replaced. I didn't notice this until now, when getting ready to winterize the pool. There did not appear to be any kind of leakage over the Summer, but it IS possible there was a slow leak...however, now I'm wondering how important it is to replace the plug? Will there be a leak throughout the winter? Is there anything in that hydrostatic hole that would be at risk if it froze?
The reason I ask, instead of just doing it, is that the water is ICE COLD, and it would be VERY difficult to get underwater to do the replacement...and I'm not trying to rent a drysuit or a diver!
Thanks in advance for advice...really hoping this is not a major issue!

Re: Hydrostatic plug left out by mistake
Hi sohungry,
It would be incredibly unlikely for anything to achieve a frozen state that deep so no damage should happen. The valve itself is designed to allow water build up under the pool shell to escape into the pool rather than lifting the shell out of the ground.
It should not have a plug in it, just the spring non return valve, unless I misunderstand you?

Re: Hydrostatic plug left out by mistake
Right, yes, the valve...I've seen it referred to as a plug or valve, but yes I think "valve" is a more accurate term, probably.
So, realistically, at this point there is just a hole in the bottom of my pool, that empties into a sand/gravel pit? I don't know why it wasn't draining out over the summer, I guess the groundwater had just hit an equilibrium?

Re: Hydrostatic plug left out by mistake
Maybe, if you have a high water table. One of my customers opened their pool spring before last to the most disgusting smell and sight because of high water over the winter. Hope you are luckier. What you need is a women to put the valve in for you, they can do this because they are better at pain having gone through childbirth, oh and they don't have testicles!

Re: Hydrostatic plug left out by mistake
Great advice; I'll just go ahead and explain that to my wife, and then get back and update you after the divorce proceedings
So, you're saying it isn't NECESSARY to replace the valve, but it is a good idea?
The one part I left out, because I wasn't sure yet (and I'm still not)...I had to lower my water level prior to winterization so an electrician could come and finish up an incomplete light installation. Now, as I'm trying to raise my water level with my hose, it isn't rising nearly as fast as I expected it to, and for that reason I suspect there may be a leak, and I think that this valve is the most likely culprit. I'm no hydrophysicist, so I don't know why there would be no leak (or negligible leak, I guess) when the pool was full, but is now gushing out inches at a time...unless the water is pouring out the bottom, going straight into the water table, straight into the well, and then cycling straight back out the hose!
I left the water on all day while I was at work, and I'll check it in a few hours when I get home, and I'll be able to make a better assessment I HOPE!
Thanks, Teapot, for your patience and advice!

Re: Hydrostatic plug left out by mistake
No problem, just explain to your wife this guy suggested that you go in the pool, in the interests of science you understand..........let me know the rest LOL
On a serious note: Be interested to see how you get on with the pool.

Re: Hydrostatic plug left out by mistake
Water seeks it's own level, so once you have equal water in the pool and water table there will be no movement
When they replastered was water coming into the pool from the hydrostatic relief valve if so they may have plugged it
I would be inclined to drain down to a wader level, replace the valve if possible and hold it down with a weight with a rope on it to pull it off when you have sufficient pool pressure to hold it in place
