Holes in liners can be patched, even under water, with pool patch kits, using vinyl and vinyl adhesive (Boxer Brand Adhesive is best). It's easy to tell if it's an overhang liner.

If you are a new pool owner, and it's a round AG pool, I strongly suggest you learn our B-B-B method of pool maintenance and practice it FIRST, before you invest $1000 or $2000 in a salt water chlorine generator which will NOT pay for itself.

I have an SWCG, and I love it, but I bought it with my eyes open: I'm away a lot and it allows me to maintain the pool easier not being there, but it is NOT because I hoped to save money on chlorine--I don't.

If you're can spend 2-5 minutes a day, and 15 - 30 once a week, the B-B-B system is easy, even fun, and you'll save incredible amounts of money on your pool chemicals and in NOT hiring pool services.

Best of luck Dustin.
