This is my first post so be gentle :P
I'm in my 4th summer with an in-ground vinyl lined pool. Since new, I've had to pump water out from behind the liner. The pool installer worked on this for the first year with repeated attempts at repair around the stairs. The following year I had a local and highly recommended leak detection company do a leak search which lead to another repair (patch) at the stairs. BTW, the pool installer is no longer in business.
To remedy the situation, i've constructed a piece of PVC pipe that I insert where most of the water collects and pump it out with my vacuum hose into the skimmer. I've tested the water behind the liner for salt as one pool repair/service company though it may be ground water, which it isn't.
So i guess what my question is, is there a product or technique I should try to remedy this? Everyone who's been involved in this has finally suggested that I replace the liner.
I would like to make sure I've investigated every avenue before dropping the $5k to replace the liner.
Oh one more thing.. what a fantastic forum/website!!!
