Note to moderator keep topic here or move to above ground?
Over the years I've done leak detections on above ground pools, sometimes the leak ends up being numerous pin holes along the perimeter of the pool in the cove. I don't see any scrape marks from a vacuum head or brush just pin holes, I've searched Google and http://www.shadebuilder.com/above-groun ... takes.html says it's from auto cleaners or vacuuming near the cove. But like i just mentioned I see no scrape marks just pin holes, I theorized maybe insect damage, poor quality reprocessed vinyl, small stones or sand behind the liner rubbing through the material. What is weird is that I've never seen these type of holes in this patten in an in-ground liner pool (maybe because AG vinyl has the textured backing?). Anyone have an idea?
