Section 8: Plumbing System
Fresh Water Holding Tank
There may be several ways to fill the fresh water tank depending on the model. For details
of each method, refer to the Fresh Water Connections or the Utility Center (if so equipped)
sections. There are plastic overflow tubes in the fresh water holding tank which allow water
to flow out of the water tank (see City Water Fill). Occasionally, you may see water coming
from the overflow tubes when the fresh water 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.
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.
12-Volt Water Pump & Switch
When you want to use water in your recreation vehicle and it is not hooked up to city water,
you will need sufficient 12-volt DC power to run the water pump.
Once activated, the water pump (also known as the demand pump) will self-prime,
and provide water.

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 and clear any
debris, then reinstall.
For additional information on the care and operation of the pump, read the safety and
operating information in the pump manufacturer's owner's manual.

center. When the water pump switch is ON the pump
runs until 45 lbs. of pressure has been achieved. The
red light will stay on. The water pump automatically
recycles when pressure drops. Some cycling may occur
depending on the volume of water being released. Turn
the water pump switch OFF when it is not in use.
