Hi- we are replacing the 10 year old vinyl liner in our in ground pool. It has many rips and tears and the bottom is bleached white! I find it interesting that the sides haven't really bleached or ripped at all, and thus assume that in our case, the damage is from UV exposure rather than water balance problems. Our pool gets full sun from about 11am to 6pm and we live in the south.
I've been reading that 20 mil liners are fine for most pools, and are generally easier to install, but I wonder if we ought to consider a thicker gauge since our pool gets so much sun?
Also, I've been reading online that the pigment in bright royal blue liner ink tends to fade more quickly than lighter blues, turquoise, tans, and dark blue. Have any of you heard or experienced this?
