Automatic pool cover vault has a lot of water: ways to stop this?

[benconrad30]

I have a new automatic pool cover going in soon. The current pool vault and tile wall is below the other edges of the pool and gets a lot of water in it. Are there anyways to stop this waste of water? Has anyone tried turning the pool vault/trench into part of the pool and just pump the overflow of the water back into the pool with a sump pump or anything? Maybe sealing the drain first in the automatic pool cover trench. 1 inch of wasted water could be 200-212 gallons of water every time the kids swim. Building up the tile pool wall/vault wall is not going to work with the automatic pool cover.
Thank you in advance for all the help.

Welcome to TFP.

Seems to be a common problem with an autocover...

Is anyone experiencing water loss over the vault dam as described in this post? https://www.troublefreepool.com/threads/water-loss-into-autocover-box-trench.216465/

Water loss into autocover box/trench

I’m a first time pool owner with an autocover. The pool was just built and I love it. I have been wondering about water loss. It seems that when we get lots of kids jumping around the pool I seem to lose a lot of water into the autocover trench/box (could lose an inch from one evening of kids...

Look on the bright side. Without the autocover, you'd probably lose the same amount of water to evaporation in warm weather.

After they installed cover was it better than you expected?

I was thinking of putting a clear silicone strip on the tile slope to prevent water from easily spilling out. Using some of the stuff that can seal glass shower walls/doors. I have seen some called threshold shower dam - but I never tried it.

My other idea is to rig up some sort of moving rubber flap that attaches to the cover bar - it could seal against the tile slope when open - sort of like door sweeps that get tighter when a door is closed....I was thinking some metal clips that you could rotate the rubber down to seal off the area...
