1. After the pool holds water, always be aware of the water level in your pool. Detect and repair leaks as fast as possible, or you chance having to replace the pool liner, no matter how old it is.
  2. Never pump the water out of your pool. If you do, the chances of having to replace the liner are great. If your pool is filthy dirty, do not pump the pool out. Clean it with chemicals and filtration.
  3. Pool liners are fairly thin vinyl. They are not resistant to punctures. Try to eliminate situations that promote punctures.
  4. Maintain your pool at a high level. The better you maintain your pool, the longer the liner will last.
