• Inspection and joints should be performed by an
authorized motorhomes service center. If resealing is
necessary, it is the owner's responsibility and is not
covered by the Tiffin Motorhomes Limited Warranty.
• Sanitize the fresh water system.
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, perform the following instructions:
1. Drain all the water from the water system including the holding tank(s), the water heater
and fresh water tank. Also drain the water filter. For the holding tank(s), open the gate
valve(s) to drain the tanks. Turn off the 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 outer 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 water tank drain located at the rear of the motorhome. When empty 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 to the sanitize/winterize position.
3. Connect a vinyl hose to the inlet valve on the sewer board and place the other end of the
hose into a gallon of fresh water 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 flow through the piping. Let about one cup drop into the drains to protect the
P-TRAPS.
5. When all of the antifreeze is withdrawn from the bottle, disconnect the vinyl hose from the
inlet valve on the sewer board. (This procedure may require more than one gallon of
antifreeze).
6. When the winterizing process is completed, turn the water pump "OFF" and store the vinyl
hose for future use. (NOTE: DO NOT use the vinyl hose that was used in the winterizing
process when connecting your motorhome to a city water outlet or for filling the fresh
water tank.
