Hello All! We have decided to tackle replacing our vinyl liner in our inground pool. We have drained the pool , and have taken the old liner out. The pool needs some work. It is steel walls with vermiculite floor. We have to patch up some of the walls and some of the floor. Our major question right now is we can't get the ground water to drain out of the deep end. ...we have been using a sump pump for almost two weeks now.(We have been getting a lot of rain here in Pa!)We never had any floating with the old liner,we are only replacing liner because previous owners had a patch that was leaking.Is this a major issue, or should we just go ahead with the replacement plans?
Thanks!!
Nick

Same issue here (very high water table). Liner was sitting fine (no floating), but was very old so we are replacing this spring. Turns out we have a crack in the concrete slope between shallow and deep end. You can see a stream of water coming through at all times. The pool company that is doing our liner replacement finally hooked up a super pump (powerful) to the main drain in the floor (they removed the plug or whatever it is down there) to try to fool mother nature in a way. They are sucking out ground water I guess. Whatever it is doing it is working. There is no water coming from the crack while this thing is running so they can repair the crack. Once the crack is fully repaired, then they can worry about pumping the accumulated water from the pool and installing the new liner. Hope this might help you.

Very often when replacing a liner a pump is running 24/7 to keep water out. When u do a liner you have to be ready to go with a new liner and watch the weather for a week or more of no rain. Not a good idea to sit with an empty pool. Get going on repairs asap and throw a cheap harbor freight pump in the garden hose discharge ones work great for this
