Sanitizing the Fresh Water System
Sanitize the fresh water system before initial (rst time)
use, aer extended periods of motorhome storage, at least
once a year during continuous use, or if the fresh water
system, fresh water supply, or fresh water holding tank has
been compromised or contaminated.
1. Remove or by-pass the potable (drinking) water lter
(if equipped).
2. Disconnect and cap (or by-pass) the refrigerator ice
maker inlet water line (if equipped).
3. Disconnect and cap (or by-pass) the dishwasher inlet
line (if equipped).
4. Disconnect and cap (or by-pass) the washer inlet line
(if equipped).
5. If equipped with a dishwasher, ice maker, or washer,
follow the appropriate appliance manufacturer’s
instructions pertaining to sanitization.
6. Prepare a solution using a gallon of water and ¼ cup
of liquid household bleach (5% sodium hypo-chlorinate
solution). Use one gallon of solution for each 15 gallons
of tank capacity.
7. Open your fresh water tank bypass tube shut o valves,
or uncap them.
8. With an empty tank and all faucets and drains closed,
pump the solution into the fresh water tank, via the
water ll cap using the water pump. Or, carefully pour
1/4 cup of bleach for every 15 gallons of holding tank
capacity into your potable (drinking) water hose before
connecting it to the water source. e water source
pressure will push the chlorine and water into the fresh
water tank, making the correct dilution when the fresh
water tank is full.
9. Completely ll the fresh water tank with fresh water.
10. Switch ON the water pump. Open all the faucets one at
a time until all air is purged, and the water ows freely.
11. Add fresh water to the fresh water tank again, until the
water level reaches the ll spout.
12. Allow the solution to stand in the fresh water tank for
at least three (3) hours.
13. Drain the fresh water system by opening all faucets
and the fresh water tank drain valve while ushing the
system with fresh potable (drinking) water.
14. Continue ushing the system, allowing the water to
ow for several minutes.
15. Close the fresh water tank drain valve and the faucets.
Rell the system with potable (drinking) water.
