How many years do y'all get out of a IG vinyl liner? I'm waiting on my THIRD yes third to be made and installed in the last 6 weeks or so. Had one installed the Friday before Memorial Day...tear in seam on steps in less than a week. Liner #2 installed week after Independence Day... Tear in seam on steps 2 inches from last one in 6 days. I'm now waiting on #3 to show up and start the clock on this one. I got 8 years out of the last one now 3 in 2 months, kinda screws the life per year average up huh?
