First of all, don’t let a leaky liner stay in your pool because the water will eat the wall away – either patch it or change it.

Second, every time you change the liner examine the inside wall of your pool. If you see any rust, sand it away and spray on some corrosion eliminator.

Also,never drain your above ground pool for a prolonged time (more than an hour). The liner will shrink. Professional liner installation will help make your liner last.
