Section 8: Plumbing System
Water Pressure Regulator (customer supplied)
A water pressure regulator is recommended to prevent damage to the plumb-
ing system or components. To prevent damage when using the city water
connection, a 45 lb. (315 KPa) rated water pressure regulator is recommended.
Excessive pressure from the water supply source may be encountered in some parks, espe-
cially in mountain regions when using the fresh water inlet or black tank flush. Water pres-
sure regulators are available to protect your recreational vehicles plumbing system against
such high pressure.
Fresh Water Holding Tank
Do not cap, block or modify the fresh water tank overflow tubes in any
way. Enough water pressure can build up during the filling process to
damage the plumbing system if the overflow tubes are obstructed.
Be careful not to overfill the fresh water holding tank. It can pressurize
the tank, causing leakage and water damage and void the warranty. DO
NOT leave the tank unattended while filling.
There may be several ways to fill the fresh water tank depending on the model. For details
of each method, refer to the Utility Center or Water Connection section. There are plastic
overflow tubes in the fresh water holding tank which allow water to flow out of the water
tank. Occasionally, you may see water coming from the overflow tubes when the fresh wa-
ter holding tank is filled. This is normal and can be a result of the recreation vehicle being
parked on an incline, or the motion caused by starting or stopping during travel.
12-volt Water Pump
There must be sufficient 12-volt DC power to run the water pump when your recreation
vehicle is not hooked up to city water. Once activated, the water pump (also known as the
demand pump) will self-prime, and provide water. The water pump continues to run until
maximum pressure is achieved and shut off. The water pump will automatically re-start
when it senses a drop in the water pressure. The pump is designed for . Using the pump
continuously or with high pressure will shorten the life of the pump and is not covered in
your warranty.
Some cycling may occur, depending on the volume of water being released. The water pump
is engineered with a check valve to prevent water from back flowing into the fresh water
supply tank.
™ NOTE: The water pump switches should be in
the OFF position when the recreation for any
amount of time.
Maintenance
Periodically check the in-line water pump strainer for
accumulated debris. To clean, shut off the water pump,
unscrew the clear cap, remove the re-useable metal
strainer, clear any debris, then reinstall.
