I have a 2 year old vinyl liner that should be under warranty but the pool company that sold it to me, is possibly gone out of business and I am unable to locate a receipt to be able to get warranty coverage for a replacement. I am searching all my receipts and online statements but if I don’t find it, has anyone been successful at patching a vinyl step seam? If so, what is the best process and repair kit to use for this type of repair. We have patched our old liner before in a flat area and the patch held for a while it just made the vinyl dry and crinkled looking. We wanted to see if there are better products out there now for this sort of repair or some expert guidance in case the warranty info is not located or honored. We bought the pool kit and liner from Sunwest Pools in Las Vegas and the liner was from GLI Pools. We lost so much water after filling our pool that My husband stuffed a piece of vinyl in the hole, so that is just to temporarily stop the bleed until we get a permanent fix.
