PLUMBING
7. Disconnect the water pump inlet connection and turn the pump on until all the water
is expelled. This water, about 1/2 cup, can be caught in a towel or rag.
8. Lower the front of the trailer as far as the jack will allow until water ceases to drain,
then crank the jack up as high as it will go and let any remaining water drain out.
9. After the water has stopped running from the drain lines, apply at least 60 lbs, of
air pressure at the city water inlet. An air to city water adapter is available from your
dealer’s RV accessory store. Be sure the toilet valve and all drain valves and faucets
are open and pump outlet hose is disconnected. This can be accomplished at a
service station and will force any remaining water from the water heater and remove
any water which may be trapped in low areas.
10. Pour a cup of *approved non-toxic RV antifreeze into the lavatory, sink and tub
drains to prevent trap freeze-up.
*Approved and listed by a recognized testing authority such as UL (Underwriter Lab).
11. Be sure to open the waste holding tank drain valves and drain and flush the
tanks thoroughly (THIS IS VERY IMPORTANT AS THE SEWAGE IN THE TANKS, IF
FROZEN, COULD SERIOUSLY DAMAGE THE TANKS.)
12 Remove the cartridge of the water purifier and leave the purifier valve in the open
position. (If so equipped.)
13. Remove the batteries from your trailer and store in a cool dry place where there is
no danger of freezing. It is very important for optimum life of a battery to check it
periodically and to keep it fully charged.
14. Remove any items (food, cosmetics, etc.) from trailer interior that might be dam-
aged by freezing - or might damage the trailer if containers break.
For additional winterizing protection add a non-toxic antifreeze (approved for drinking
water system) to the water lines using the following procedure.
1. Reconnect all lines except the hose to the pump inlet port. Close all drain valves.
2. Turn by-pass valve to by-pass position. To by-pass the water heater for winterizing,
close valves A and C and open valve B (See illustration on next page).
3. Attach a length of hose to the pump inlet port. This piece of hose should be long
enough for the free end to be inserted into and reach the bottom of the antifreeze
container.
4. Dilute the antifreeze solution in accordance with the manufacturer’s instructions
5. Open all water faucets.
6. Insert hose length into the antifreeze container, turn the pump switch on, and run the
water pump until the antifreeze solution fills all water lines. Flush toilet. Work hand
shower spray while holding down in tub.
7. Shut off the pump and close all faucets.
8. Disconnect the hose length from pump inlet fitting and reconnect water system
inlet line.
