SANITIZING
Potable water systems require periodic maintenance to deliver a consistent flow of fresh water. Depending
on use and the environment the system is subject to, sanitizing is recommended prior to storing and before
using the water system after a period of storage. Systems with new components, or ones that have been
subjected to contamination, should also be disinfected as follows:
1. Use one of the following methods to determine the amount of common household bleach needed
to sanitize the tank.
A) Multiply "gallons of tank capacity" by 0.13; the result is the ounces of bleach needed to
sanitize the tank.
B) Multiply "Liters of tank capacity" by 1.0; the result is the milliliters of bleach needed to
sanitize the tank.
2. Mix into solution the proper amount of bleach within a container of water.
3.
Pour the solution (water/bleach) into the tank and fill the tank with potable water.
4.
Open all faucets (Hot & Cold) allowing the water to run until the distinct odor of chlorine is
detected.
5.
The standard solution must have four (4) hours of contact time to disinfect completely. If you
double the solution, this concentration allows for contact time of one (1) hour.
6.
When the contact time is completed, drain the tank. Refill with potable water and purge the
plumbing of all sanitizing solution.
Note: The sanitizing procedure outlined above is in conformance with the approved procedures of RVIA
ANSI Al19.2 and the U.S. Public Health Service.
Note : Two petcocks, located on the tank pans under the trailer just in front of the wheels on the roadside
are the low point drains for the hot and cold water lines. A large valve located nearby will drain the fresh
water tank sufficiently for most purposes. Total drainage may be achieved by removing the large Allen
Head Plug located on the bottom of the tank. An access plate must be removed to expose the plug.
