Pump is now ready for automatic operation. Pump will start when a faucet is opened and stop when the
faucet is closed.
Disinfecting Fresh Water Systems on Recreation Vehicles
To assure complete disinfecting of your fresh water system, it is recommended that the following procedure
be followed on a new system, one that has not been used for a period of time, or one that may have become
contaminated. This procedure is also recommended before long periods of storage such as over winter.
1.
Prepare a chlorine solution using 1 gallon of water and ¼ cup of household bleach (sodium hypochlorite
solution). With tank empty, pour chlorine solution into the tank. Use 1-gallon solution for each 15
gallons of tank capacity. This procedure will result in a residual chlorine concentration of 50-ppm in the
water system. If a 100-ppm concentration is required as discussed in item 3, use ½ cup of household
bleach with 1 gallon of water to prepare the chlorine solution. One gallon of the solution should be used
for each 15 gallons of tank capacity.
2.
Complete filling of tank with fresh water. Open each faucet and run the water until a distinct odor of
chlorine can be detected in the water discharged. Do not forget the hot water taps.
3.
Allow the system to stand at least 4 hours when disinfecting with 50-ppm residual chlorine. If a shorter
time period is desired, then a 100ppm chlorine concentration should be permitted to stand in the system
for at least 1 hour.
4.
Drain and flush with fresh water.
WARNING
Chlorine is poisonous – recap bottle and clean utensils after use.
Never use automotive type antifreeze in your potable water system, as it is poisonous.
External Water Supply (“City Water”)
To connect to an external source:
1.
Turn the demand pump switch to off.
2.
Attach a hose from the external water source to the city water connection on the
left side of your vehicle.
3.
Turn on the external water source.
When connected to an outside source of water, the water bypasses the demand pump
and storage tank and supplies pressure directly to individual faucets and toilet similar to your home. A check
valve built into the pump prevents water from entering the pump and filling the storage tank.
NOTE: Because city water pressure varies from location, we recommend using an in-line water pressure regulator to
prevent damage to any components, connections and seals in your fresh water system.
A water pressure regulator may be obtained from any well-stocked RV dealership retail center and some retail
discount centers. These devices simply connect in-line between the supply hose and the city water input on the
coach.
We recommend a regulator that controls water pressure to
40 psi maximum.
