Section 8: Plumbing System
103
Fresh Water System
All water contains contaminant and mineral particles that can cause fresh water system
odors. Untreated well water is a major source of water system odors. The fresh water
(potable water) system needs periodic sanitization and winterization to take care of all the
components in the plumbing system to discourage the growth of bacteria and other organisms
that can contaminate the water supply.
Water Pressure Regulator (customer supplied)
Excessive pressure from the water supply source may be encountered in some parks,
especially in mountain regions when using the fresh water inlet or black tank flush. Water
pressure regulators are available to protect your recreational vehicles plumbing system
against such high pressure.
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.
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. 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.
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.
A water pressure regulator is recommended to prevent damage to the plumbing
system or components. To prevent damage when using the city water
connection, a 45 lb. (315 KPa) rated water pressure regulator is recommended.
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.
