Motorhome Fresh Water System Care

Sanitizing and Chorinating the Fresh Water System

as taught by RVIA/RVDA endorsed RV Schools and as seen in FMC 3/2014

Foul or stale tasting water can ruin an excursion; it also may be harmful. If foul water persists, you may need to chlorinate the fresh water system. RVIA published this method of chlorinating the fresh water system as taught in all RVIA/RVDA endorsed RV Schools.

1                     Drain/flush fresh-water tank; leave empty

2                     Mix ¼ cup liquid household bleach (sodium hypoclorite with one gallon fresh water.

3                     Pour directly into fresh water tank through the gravity fill.

Note: If the motorhome is not equipped with a gravity fill for the fresh water tank, use a funnel to pour each gallon of mixture directly in the fresh water hose prior to connecting it to the city water source. Some motorhomes may be equipped with an alternate method of pumping the chlorinated mixture directly into the fresh water container.

4                     Add one gallon chlorine/water solution for every 15 gallons of fresh water tank capacity.

5                     Top off tank with fresh water.

6                     Remove or bypass water purification equipment and/or filtering cartridges.

7                     Turn on water pump and open every faucet in the motorhome, including exterior faucets, and shower heads.

8                     Allow solution to pump through system into toilet, through water heater, to every hot and cold faucet at each sink until the distinct odor of chlorine is present at every fixture.

9                     If applicable, at the city water inlet, gently use the eraser end of a pencil to depress the check valve and briefly allow the solution to pump out the city water inlet until the chlorine odor is detected in the discharge.

10                  Close all faucets and turn off water pump.

11                  Allow system to stand dormant for 4 hours. This will chlorinate and disinfect the system, including fresh water tank, water heater, faucets, complete piping system, and all fittings to a residual level of 50 parts per million (PPM).

12                  At four hours, drain and flush system once again and top off water tank with fresh water.

Do not allow to sit longer than 4 hours. If 100 ppm residual concentration is desired, use ½ cup bleach instead of ¼ cup for each gallon fresh water; let it stand 1 to 2 hours. If the odor of chlorines it too strong after sanitizing procedure, drain, refill and flush tank until satisfactory level of taste/odor achieved. This process should be done after extended storage, winterization, as you detect stale water, not less than once per season.
