Sanitizing Water System
It is recommended to sanitize your vessel water
system at least annually or more often when odors
are detected.
1. Flush entire system thoroughly by allowing water
to flow through it.
2. Drain system completely.
3. Fill entire system with a chlorine solution having a
strength of at least 100 parts per million, and allow
to stand for (1) hour. Shorter periods will require
greater concentrations of chlorine solutions. See
the table.
As a rule of thumb quick reference without the use
of the table to reach the recommended proportions
use a quarter cup of household bleach for every 15
gallons of water the fresh water tank holds.
4. Drain chlorine solution from entire system.
5. Flush entire system thoroughly with water.
6. Fill system with fresh water.
Winterizing Water System
Note that In freezing climates make sure the water
system is winterized to prevent damage to hoses and
components. Contact your Regal dealer since only
special alcohol based products like "Winter Ban" are
to be used in the system.
