WinterizingROUTINE MAINTENANCETo store your vehicle for the winter months, it is necessary to winterize the water system to helpprevent 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 hot water heater,and the water tank; also drain the optional water filter, if installed. For the holding tank(s),open the gate valve(s) to drain the tanks. (NOTE: This procedure is to be performed onlyat a wastewater pumping station to prevent dumping of contaminated water elsewhere). Forthe hot water heater, remove the outside cover and then remove the drain plug. When thistank is drained, replace the drain plug and then replace the cover. For the water tank, openthe green-handled valve to drain the tank; then close the greenhandledvalve. If an optional water filter is installed, remove thefilter cartridge and store it in a clean environment (e.g., resealableplastic bag); empty any excess water from the filter housing andreplace the housing.2. Turn the hot water heater by-pass valve located in the waterservice compartment to the “by-pass” position to prevent fillingthe water heater tank with antifreeze.3. Disconnect the inlet connection to the water pump [in thesanitary service compartment under the motor home] (see Figure14-15). Attach the supplied, vinyl hose (via the plastic couplingon the hose) to the inlet connection and hand-tighten thatconnection; do not over-tighten.Figure 14-15. WinterizingProcess4. Place the other end of the hose into a gallon of freshwater system antifreeze (one can referto the local Tiffin Motorhomes dealer or representative for the freshwater antifreezeformulation for your specific area). NOTE: Do not use automotive antifreeze; use onlyantifreeze approved for RV applications; otherwise, damage to the systems being protectedmay result.5. Turn “on” the water pump to start the flow of antifreeze. Turn “on” each faucet, one at atime, and allow pure antifreeze to run through that piping. Let about one cup drop into thedrains to protect the traps.6. When all the antifreeze is withdrawn from the bottle, disconnect the clear vinyl hose fromthe water-pump inlet connection and reconnect the inlet line to the water pump. (This mayrequire more than one gallon of antifreeze).7. When the winterizing process is completed, turn the water pump “off” and then reconnectthe water line. Store the vinyl hose for future use.14-35
