Hi I have been reading TFP for some time and have really learned a bunch! Thanks all.
We are in the process of building our own pool and I have a question about ground water. We are into bed rock about 3 ft and will have some ground water issues. We have 1 main drain 1 skimmer and have put a third line under the main drain in clear stone with a special filter type end 1 1/2" pipe with slits cut in it. Can we run all three return lines to the pump with a valve on the 3rd line we can crack open and suck the ground water from under the main drain and into the pool if we see the liner lifting? Also how would I plumb a line for overfill protection?
in the works....20 x 40 in ground (rock) vinyl liner
