Look for a Warranty

Rips and tears are not unheard of when it comes to in-ground pool liners. Small tears may be repairable, but large rips can cause significant problems. Many pool supply dealers sell liners that are heavily inspected for defects and packaged in heavy-duty boxes for protection. Choosing to purchase from a dealer who takes care with packaging and inspection can mean the difference between receiving a quality liner and something flimsy and in poor repair.
To protect yourself against defects and unhappy surprises, be sure your in-ground pool liner comes with a warranty. Learn the details of the warranty before you make your purchase. Your pool dealer should be happy to explain the warranty to you and even let you read it in advance. If not, move on to another dealer.
