I ordered an 18" pool liner on March 30, 2022. I paid for the more expensive one, thinking it would last longer. We put the liner in April 21 and it looked good. As the water started filling up the liner made a diamond shaped hole tearing. We stopped the water and called Doheny. They said we had to go through Swimline for the warranty. So I sent her pictures. Today, May 3, Kim at Slimline, 'finally' told me "we only cover tears at the seam". UMMMMM, so your defective product that I am just filling up water and got a hole it from filling it up, you will not cover?" I am LIVID and if you are smart DO NOT BUY A LINER FROM THEM.
