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: A petcock, visible between the tires, will drain the 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 from the tank pan
to expose the plug.
