Leak or Excess Water

[G80rGirl]

Recently put up my 16' round INTEX AGP. It is set up on an 18' concrete pool pad that I have used for 8years now. This year my concrete pad had two cracks going across it. I've noticed a lot of water coming from underneath the liner. It seems to be between the pad and concrete and not the liner and pad. Is it possible that the weight of the pool could cause ground water to come up through the cracks in the concrete and then out from under the liner?

I did the bucket test and it was equal water loss and concrete dried up, but then it rained a couple of days and my nieces played in the pool a couple days and now the water around pool is back (and worse). I've lost about 1" of water in 48hrs. I probably need to do another bucket test. Just wondering if anyone had any thoughts on the concrete oozing water!

Welcome to TFP! It would seem odd that water would seep upwards out of the ground and through the concrete like that. I'm leaning more towards the pool, but definitely take your time and inspect all areas of the pool really well. It only takes a tiny pinhole to create a mess.

Leak Detection

A number of things can cause leaks in your pool. You can learn tricks for leak detection and how to pinpoint where your pool is losing water.

Weight of the water will not allow water to travel upwards. Gravity intervenes.

How wide are the cracks in your concrete slab? could the liner have been pushed down into one of those cracks and slit?

Thanks for the reply. The cracks are really small, more like hairline. I also have floor underlayment between concrete and liner, so I don't think it could be in the crack.

Yeah, I doubted it was the cracks, too.

An inch of water in 48 hours is a very small leak but a leak nevertheless.

Can you get the nieces back in there to search with there young eyes?

Interesting update: a week later and the pool continues to leak until a bad storm hit us Saturday. We lost power and have been without it for 4 days (still out). BUT the leak has stopped. Why?? I know I am not losing water near any of the fittings, valves, hoses, pump, etc. This doesn't make sense to me.

Ground is saturated with water after the storm so the leak has stopped until the soil drains/dries. If this is the reason, than more than likely your leak is somewhere at the bottom where the liner meets the ground.

My pool is on a concrete pad.
