Sanitizing
To assure complete disinfecting of your fresh water system, it is recommended that the following
procedure be followed 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 over the winter months:
1.
Drain the fresh water tank by opening the drain valves. There is one valve per 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 1⁄4 cup of chlorine bleach (5%
sodium hypo-chlorite 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 higher than 50 PPM may
damage the water lines and/or tank.
3.
Once the fresh water tank is empty, close the drain valves on the water tank.
4.
Pump the chlorine solution into the tank. This is done by 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 fresh water tank.
5.
Turn off the water pump. 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 by-pass pipe to allow the sanitizing solution
access to the faucet. Open each faucet in turn including the kitchen faucet, bath faucet, inside
and outside shower, turning on both the hot and cold, and flushing the stool 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 with fresh water. The water system needs to be flushed with clean
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 vinegar to five gallons of water. Allow this solution to agitate in the tank for several
days by vehicle motion. Drain the solution and refill the tank with clean water.
IMPORTANT
Make sure the chlorine bleach solution is thoroughly and completely purged from the plumbing
before using the fresh water system. Also, never use alternative cleansers; only potable materials
may be used in your fresh water plumbing system.
