Paying a little bit more for a liner that you'll never have to replace is worth it! Add the Horizon pool pad and cove kit to the liner purchase and the 100% Warranty will extend not only to seam separation but to any other failure of the liner due to manufacture defects.
Vinyl pool liners form the waterproof barrier that keeps the pool from leaking. Pool liners on above-ground and in-ground pools are held in place by a track. The liner can pop out of the track for various reasons, including damage to the track, liner shrinkage or water behind the liner.
