Section 8: Plumbing System
112
1.
Turn water heater power OFF. Turn water heater gas valve (if so equipped) OFF
(outside of the RV).
2.
Water heater bypass should be set to BYPASS. Refer to Water Heater Bypass Diagram.
Water is prevented from entering the water heater.
3.
Level the RV and drain the fresh water plumbing system. See Draining the Fresh Water
System.
4.
Water heater should be empty after performing Step 2. Water heater bypass should still
be ON (if so equipped).
5.
Cartridge water filter (if so equipped) should be removed and replaced with the bypass
hose included with your RV.
6.
Make sure the “fresh water tank drain” and “low point drains” are closed.
7.
Close the fresh water tank shutoff valve (if so equipped). Valve should be located in the
vicinity of the water pump. Open siphon valve on the water pump with the clear hose
attached and insert the opposite end of the clear hose into a container of RV antifreeze
solution. Valve should be located in the vicinity of the water pump. See Water Heater
Bypass section.
8.
Turn the water pump ON. Antifreeze will be drawn into the water lines.
9.
Open the hot water faucets, including outside shower (if so equipped) until RV
antifreeze begins to flow continuously.
10. Close the hot water line faucets and outside shower and repeat with the cold water line
faucets. Hold open the lever on the toilet until antifreeze runs into the bowl.
Winterize the Macerator System (if so equipped)
The macerator system can retain water in the flexible hose and dump connector attached to
the flex hose. Pour antifreeze into the dump connector and into the 1-1/2 inch flexible hose.
Raise the hose allowing the antifreeze to run back down to the macerator pump. Return the
flex hose and dump connector to the storage box.
Water can accumulate in the flexible hose and dump connector of the macerator
system. When winterizing the RV, antifreeze must be added to the macerator
system.
NOTE:
In order to create a suction all low point drains must be
closed.
NOTE:
Antifreeze should never enter the water heater, RV water
filter, refrigerator, refrigerator water filter, or fresh water tank.
