fresh WAter holdinG tAnk
There may be several ways to ll 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 overow tubes plumbed into the fresh water holding tank which
allow water to ow out of the water tank (see City Water Fill). Occasionally, you may see
water coming from the overow tubes when the fresh water holding tank is lled. 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.
Never travel with full fresh, black or grey water holding tanks..

Be careful not to overll 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 lling.

Do not cap, block or modify the fresh water tank overow tubes in any way.
Enough water pressure can build up during the lling process to damage the
plumbing system if the overow tubes are obstructed.

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 sufcient 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. The pump is designed for intermittent use only. Using the pump
continuously or with high pressure will shorten the life of the pump and is not covered in
your warranty. The water pump is engineered with a check valve to prevent water from back
owing into the fresh water supply tank.
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.
Water Pump Switch (if so equipped):
Most water pump switches illuminate when the water pump is activated. In most models,
the (red) pump switch is located on the monitor panel or the utility center. When the water
pump switch is ON the pump runs until 45 lbs. of pressure has been achieved. The red light
