All of the water should be drained from the freshwater system when the motor home is not in use
for an extended period of time.
Sanitizing
To assure complete disinfecting of the freshwater system, it is recommended that the following procedure be
performed on a new system, on one that has not been used for a length of time, or one that may have become
contaminated. This procedure is also recommended before long periods of storage, such as during the winter months:
1. Drain the freshwater tank by opening the drain valves. There is one valve for each water tank. All of the faucets
should be in the closed or “off” position.
2. Prepare a chlorine solution using one gallon of water and one-half cup of chlorine bleach (5% sodium-
hypochlorite solution). Prepare enough of the chlorine solution to administer one gallon of solution for every
15 gallons of tank capacity. For sanitizing this unit, prepare 4 1/2 gallons of the chlorine solution. This mixture
puts a 50 ppm (parts per million) residual chlorine concentration in the water system that will act as a quick-kill
dosage for harmful bacteria, viruses, and slime-forming organisms. Concentrations greater than 50 ppm may
damage the water lines and/or the tank.
3. Once the freshwater tank is empty, close the drain valves in the water tank.
4. Pump the chlorine solution into the tank by first placing the winterizing hose into the chlorine solution. Close
the valve from the fresh water tank to the pump and open the valve from the solution to the pump. Turn the
tank fill valve from “city water” to “tank fill.” Turn “on” the water pump until all of the solution is pumped into
the freshwater tank.
5. Turn “off” the water pump. Then close the valve to the solution. Open the valve from the
tank to the water
pump. Fill the water tank with the city water tank fill (or by using the same method as was used to put the
sanitizing solution into the tank). Remove the water filter (from the drink dispenser faucet, if installed) and install
the bypass pipe to allow the sanitizing solution access to the faucet. Open each faucet, in turn, including the
kitchen faucet, bath faucet, inside and outside showers, turning “on” both the hot and cold faucets and flushing
the toilet until all of the air has been purged from the pipes and the water runs freely. The entire system will
then be filled with the sanitizing solution.
6. Allow the 50 ppm disinfecting solution to stand in the system at least four hours.
7. Drain the system and flush it with freshwater. The water system needs to be flushed with water repeatedly, if
necessary, until there is no chlorine taste or smell left in the system. To remove any excessive chlorine taste or
odor that might remain, prepare a solution of one quart of vinegar to five gallons of water. “Rock the tank
containing the solution by moving the vehicle forward and backward several times to clean the tank; then
drain that tank and refill with clean water.
Important
Be sure the potable water fill cap is removed when filling the water tank from a city
water supply (which is typically under 60-80 psig pressure). Failure to do so may
result in inadvertent expansion of and possible rupture of the water tank.
