Potable water systems require periodic maintenance to keep components
working and to deliver a consistent ow of fresh water. Depending on use
and the environment the system is subjected to, sanitizing is recommend-
ed prior to storage and before using the water system after a period of
storage.
If water is left to freeze in the water system, serious damage to the plumb-
ing and the pump may occur. Failures of this type will void the warranty. The
best guarantee against damage is to completely drain the water system.
