Do you have a robotic pool cleaner? I have written under another post about my Dolphin and my liner.

I have also discovered that it is not uncommon for carpenter ants to eat vinyl liners.

In either case, find a liner repair service in your area. The guy I found repaired over 100 small slits in my shallow end for $225.00! He uses dive gear for access, and made the patches out of the leftover liner cuts from when my pool was built in 2002. It took him about 2 hours, and he was very thorough.

I seriously considered filling my pool in also. It just comes with the territory.
