Sanitizing the Plumbing System
When to sanitize:
When your recreation vehicle is new.
At the beginning and end of each season.
When the water system becomes contaminated or every three months of use.
Preparing to sanitize
1.
Prepare a chlorine solution using 1/4 cup of household bleach (sodium hypochlorite
solution) to one gallon (3.785 liters) of water in a container. Prepare one gallon of solu-
tion for every 15 gallons of tank capacity. This will result in a residual chlorine concen-
tration of 50 ppm in the water system and should remain in system for at least 4 hours.
If a 100 ppm concentration is prepared, use ½ cup of household bleach with one gallon
of water. One gallon of the solution should be used for each 15 gallons of tank capacity.
Allow to remain in system for at least 1 hour.
™ NOTE: Fresh water tank sizes vary by model. Contact your dealer or cus-
tomer service for your specific tank size.
How to sanitize
1.
Turn water heater power OFF (storage style-both electric and LP gas switches; tank less
water heater turn power switch OFF).
Set the bypass valves to the BYPASS position.
2.
3.
Level the RV and drain the fresh water system (see Draining the Fresh Water System).
4.
Close the low point drain valves and the fresh water tank drain valve.
If the RV has a cartridge type water filter it must be removed and bypassed using the
5.
(supplied) bypass tube. Sanitizer should never be allowed into a water filter.
6.
Put the sanitizer solution in the fresh water tank. Insert one end of a hose (or funnel) in
the gravity fill inlet; insert the other end into a container holding the chlorine solution.
Do not use your non-toxic drinking water hose. Pour the chlorine solution into the
gravity fill.
7.
Remove the hose (or funnel) and container used to pour the chlorine solution, and con-
tinue filling the fresh water tank with clean (potable) water until tank is full. Pour fresh
water into the gravity fill inlet until tank is completely full. After the recommended
amount of sanitizing solution is in the tank, the water tank is full, the water filter has
been removed and bypassed, and the water heater has been bypassed, turn the pump
ON which sends sanitizer into the water lines.w
8.
Turn the pump on to send water through the lines. Open all hot water faucets one by
one until water begins to flow continuously and a chlorine smell is noticeable. Include
