JAYCO TOWABLE SECTION 8 – PLUMBING SYSTEM
8-9
Periodically inspect the vent for obstructions. Do not terminate the vent on your water
heater inside of add-on rooms, screen porches or patios. Doing so will result in products of
combustion being vented into the rooms or occupied areas.
Draining and winterization:
If the recreation vehicle is to be stored over the winter months, the water heater must be
drained to prevent damage from freezing. Damage to the water heater caused by freezing is
not warrantable. It is recommended the water heater be drained and bypassed during the
winterization process, particularly if introducing RV antifreeze into the plumbing
system.
NOTE: The water heater should never be drained when HOT or UNDER
PRESSURE.
To drain the water heater:
1. Turn off electrical power to the water heater either at the switch from the electrical
element of at the breaker.
2. Shut off the propane supply to the water heater.
3. Turn off the pressure pump on the water system.
4. Open both hot and cold water faucets.
5. Remove the anode rod from the tank.
For detailed information see the Winterizing The Plumbing System and Water Heater
Bypass sections of this manual.
3 VALVE WATER HEATER BYPASS (IF SO EQUIPPED)
Most floor plans have a factory installed water heater bypass which enables you to avoid
filling the water heater with RV antifreeze. Bypass valves are typically located in close
proximity to the water heater. Outside utility centers (if so equipped) operate differently
than a factory installed bypass system. Refer to the Outside Utility Center section for
details.
