We fought several tiny holes in the bottom corner of the liner last year. Patched and patched. It seems we have more as we are losing water in that same area (ground wet). Pool installer said it was probably ants or termites. The house next door to us had termites, and we did have the area around the pool sprayed for ants during the time the problems first started.
At what point do you stop fighting and just start over with a new liner and better bottom/cove protection? It will be at least 2 1/2 months before it is warm enough for me to try and patch anything. Pool installer quoted price of $450 to install new liner (plus the price of the liner). The pool is only 3 years old. Does that price sound right? Thanks in advance for all the advice!
