Can I use drain for water behind liner?

[brbrian]

Have this drain beside pool and previous owner said I could use it to drain out water from behind liner if ever needed. What is this kind of drain called and how does it work? Seems every time it rains here the liner starts to float, this would be really helpful if it does work that way.

We call them well points here and you have to connect a pump strong enough to pull the water

So, now I have a pump connected to well point and it's taking out a lot of water that I'm sending to my waste water outlet, pump has been going continuous for 3 hours now with a stream of water that looks like it would if water was on all the way. I still have standing water in yard also, any guesses as to how long I should keep pump going or how much water can get behind liners?

When having our liner replaced several years ago, the pool guys ran it for week! If u have had so much rain that it's still standing in the yard...I would say run it until there's just a trickle coming out.

Thanks, finally ran dry after 6 hours.

I find this really fascinating. I've never lived anywhere that had groundwater anywhere near the surface.

A lot of flat land areas can do this as well as valley floors. In the OP's case it wasn't just water "behind the liner" . It was, or could be, acres of area that need to be drained from around the pool. He only really needs to get the water below the level of the water in the pool to keep the liner from floating.


We have several gravel pits in my area that have standing water in them from the water table level. One guy who was not familiar with the area bought one of them and thought he could pump it out to continue mining. Had a large volume pump running for several years but never made a dent in it. The level would fluctuate throughout the year by about 10 feet but never much more than that. Fortunately for us, the level stays about 30-35 feet below the level of the land in the flat areas. Makes it nice if you want to hand drive a well for irrigation though.
