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 ush. Water pres-
sure regulators are available to protect your recreational vehicles plumbing system against
such high pressure.
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 overow tubes in 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 overow 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 start-
ing or stopping during travel.
When you want to use water in your recreation vehicle and it is not hooked up to city water,
you will need sucient 12-volt DC power to run the water pump.
Once activated, the water pump (also known as the demand pump) will self-prime, and pro-
vide water. 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.
Periodically check the in-line water pump strainer for accumulated debris. To clean, shut o
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 operat-
ing information in the pump manufacturer’s owner’s manual.
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
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.
Do not cap, block or modify the fresh water tank overow tubes in any
way. Enough water pressure can build up during the lling process to
damage the plumbing system if the overow tubes are obstructed.
Be careful not to overll 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.
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.
