step 10.
8. Connect a blowout valve to the city water inlet. Connect a
compressed air source.
9. Open each tap (bathroom, kitchen, exterior shower, and
toilet) both hot and cold. Allow the air to blow the remaining
water out of the taps and valves. Fully drain the system.
Leave all taps, toilet valve and drain valves in an open
position.
10. Pour ½ cup of non-toxic, RV antifreeze down each drain.
7. Remove the water line from the inlet side of the water pump
(this is the clear plastic line going into the water pump filter).
Connect a siphon hose to the inlet side of the water pump
and place the other end in a container of non-toxic, RV
antifreeze. Turn on the pump. This will pump non-toxic RV
antifreeze through all of your fresh water lines.
NOTE:
Siphon hose consists of 40” of ½” clear tubing with a
fitting to attach to the water pump. The fitting can be purchased
through an RV dealer.
8. Open the kitchen faucet, exterior shower faucet, interior
shower and bathroom faucet one at a time allowing the
antifreeze to flow through both the hot and the cold sides.
Open the toilet valve and allow antifreeze to flow into the
toilet bowl. Turn off the water pump and disconnect the
siphon hose. Reattach the original fresh water supply fitting.
9. Pour ½ cup of non-toxic, RV antifreeze down each drain
(kitchen sink, bathroom sink and shower drain).
10. Open the low point drain valve on the white water line for
water heater recirculation.The low point drains are located
under the vehicle, in front of the driver rear tire.
11. Open your grey and black water tank valves one last time
to ensure all water from the holding tanks is completely
drained. Once drained, close your grey and black tank valves
for winter.
