Water Behind and Under Liner

[Viflux]

Hello,

I'm in Southwestern Ontario, Canada, and we've had a lot of rain this past summer. In 1 60-minute downpour in July, we had more rainfall than we had the entire summer of 2023. Early this season I noticed that my liner had become unclipped in one spot (about 4 inches). My pool company was/is going to address at closing and I didn't think much of it. With the downpour in July, the water level topped the liner and I later realized the water escaped behind the pool liner.

I've since been able to pump the water out using a transfer pump. Smoothed out the liner and it was all good.

Except a few days later, there's water behind the liner again.

The real mystery to me is that I've tested the water behind the liner (test strips) and it's completely untreated water. That leads me to believe it's ground water seeping in (vs. a leak).

Anyone have any thoughts on this? How would I go about permanently stopping the situation?

Show us pictures of your pool and the problem area.

What type of deck is around the pool?

Would it be suprising you have ground water around your pool with all the rain you had this year?

Hi - thank you and sorry for the delay. Got sidetracked with the back-to-school flu.

Attached is a photo of the pool. Hard to take a picture of the problem area when it's not really visible. While in the pool you can feel "squishyness" around the edges (wall meets floor) and walls. It goes away temporarily if I pump out the water but keeps coming back.

It's not surprising to have elevated levels of ground water. It is surprising that it's posing this much issue for my pool (at least, I think it is...). We've never had this issue before in the spring with the snow melt when there's also lots of ground water.

Having well points around a liner pool is the way to handle ground water.

Can anyone tell me about well points and liner float?...

We have a liner pool, new last Sept. We have had a lot of rain lately and last night my girls noticed the liner was "mushy" in spots. I went out and sure enough there was water behind it. The water level in the pool never went above the coping. We have the pool crete on the bottoms and side...

Where should we put the Well point by the pool? High water table.

Hi, We are getting ready to have a 16' x 34' vinyl pool installed with a constant depth of 52" to the middle of the skimmer. We have a very high ground water level and want to make sure that it is properly drained around the pool. They will backfill around the pool with crushed gravel. We...

Preventing liner from floating

Every spring when I open the pool the vinyl liner has floated because the ground water is so high. It is a real pain to fix and I never get all the wrinkles out. Has anyone found a solution to this? I was thinking I might put some weights or sand bags around the perimeter this year. Any idea...
