The problem that exists with salt water is that it has become very popular in recent years and many have been installed incorrectly by under-experienced installers or pool owners. This is the same reason that you should never add chlorine pucks to the skimmer basket or pump strainer basket in your pool. The LPG company might advise you without cost, or maybe not.

If advanced corrosion is detected inside the heater then the assumption is made that the water in the pool has not been maintained properly.
