We ordered a new above ground pool liner from PoolSupplies. The Liner arrived quickly in just a few days. Unfortunately it was discovered by my installer during removal of the old liner that our pool wall had seriously deteriorated where the skimmer is attached as well as a few of the bottom rails for the pool wall. This was not totally unexpected as the pool was very old. The return of the liner to Poolsupplies was simple and they also were very helpful in sending me a FedEx shipping label at a much lower cost than thru UPS. PoolSupplies was great throughout the whole process.

I bought the liner with cove moulding and a rhino pad. The 25 mil liner seems plenty thick but still will stretch where needed. I did it with no help one step at a time. Tamp the sand down when damp and add the pad.it came out pretty smooth, better than before.I think cove moulding is necessary

The liner arrived very quickly. I think two days after I placed the order the directions were good. The liner went on just the way it should've I believe. Got it filled with water and enjoying the pool. Thank you for your quick service and quality product.
