- Living in an area that is susceptible to ground water problems (e.g clay).
- Maintaining chemically balanced water in the swimming pool.
- The fit of the liner. A liner is custom fit to your pool and it is critical that the measurements are accurate prior to the manufacturing process.
- The use of a winter cover has numerous benefits and can add years of life to a liner. The cover protects the liner from the harsh winter sun, keeps potentially harmful debris out of the pool, protects the liner from being pervaded by red dye from rotting leaves, and best of all, upon opening your pool, the water is swim-ready in no time.
There are a few reasons for replacing a liner. In the event the liner no longer holds water, i.e. it leaks, and patching is no longer an option as with age the vinyl becomes brittle and a patch will no longer bond to it. Another common reason is aesthetics, as liners get older their patterns tend to fade and new patterns also become available.
