WINTERIZING

To store your vehicle for the winter months, it is necessary to winterize the water system to help
prevent freezing of this system. To do this, follow these instructions:
1. Drain all the water from the water system including the holding tank(s), the water heater and
freshwater tank. Also, drain the water filter. For the holding tank(s), open the gate valve(s) to
drain the tanks. Turn off water heater before draining to prevent burning the element out.
(NOTE: This procedure is to be performed only at a waste water pumping station to prevent
dumping of contaminated water elsewhere). For the water heater, remove the outside cover and
then remove the drain plug. When this tank is drained, replace the drain plug and then replace
the cover. For the water tank, open the red-handled valve to drain the tank; then close the valve.
Remove the filter cartridge from the water filter and store it in a clean environment. Empty any
excess water from the filter housing and replace the housing.
2. At the sewer board turn the blue handle valve to the sanitize/winterize position turn the red
handle valve to the bypass position.
3. Connect a vinyl hose to the inlet valve on the sewer board place the other end of the hose into a
gallon of freshwater system antifreeze. NOTE: Do not use automotive antifreeze; use only
antifreeze approved for RV applications. Otherwise, damage to the systems being protected may
result.
4. Turn "on" the water pump to start the flow of antifreeze. Turn "on" each faucet, one at a time,
including the kitchen faucet, bath faucet, inside and outside showers and allow pure antifreeze to
run through that piping. Let about one cup drop into the drains to protect the traps.
5. When all the antifreeze is withdrawn from the bottle, disconnect the vinyl hose from the inlet
valve on the sewer board. (This may require more than one gallon of antifreeze).
6. When the winterize process is completed, turn the water pump "off". Store the vinyl hose for
future use.
