PLUMBING & BATH FEATUREStank has been reached. This pipe is installed in the freshwater tank to prevent possible tank rupturefrom inadvertent overfilling.All of the water should be drained from the freshwater system when the motor home is not in usefor an extended period of time.SanitizingTo assure complete disinfecting of the freshwater system, it is recommended that the followingprocedure be performed on a new system, on one that has not been used for a length of time, orone that may have become contaminated. This procedure is also recommended before long periodsof storage, such as during the winter months:1. Drain the freshwater tank by opening the drain valves. There is one valve for each watertank. 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 administerone gallon of solution for every 15 gallons of tank capacity. For sanitizing this tank, prepare4½ gallons of the chlorine solution. This mixture puts a 50 ppm (parts per million) residualchlorine concentration in the water system that will act as a quick-kill dosage for harmfulbacteria, viruses, and slime-forming organisms. Concentrations greater than 50 ppm maydamage 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 thechlorine solution. Close the valve from the fresh water tank to the pump and open the valvefrom 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 thetank to the water pump. Fill the water tank with the city water tank fill (or by using the samemethod as was used to put the sanitizing solution into the tank). Remove the water filter(located in the sanitation compartment outside the motor home) and install the bypass pipeto allow the sanitizing solution access to the faucet. Open each faucet, in turn, including thekitchen faucet, bath faucet, inside and outside showers, turning “on” both the hot and coldfaucets, and flushing the toilet until all of the air has been purged from the pipes and thewater 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 withwater repeatedly, if necessary, until there is no chlorine taste or smell left in the system. Toremove any excessive chlorine taste or odor that might remain, prepare a solution of one11-5
