WaTEr SYSTEMS
The motor home plumbing system has the dual ability to be self-contained with on-board storage, or use facilities
provided by an external pressurized source. In either case, the components of the system operate like those in your
home. Components of the plumbing system consist of strong, lightweight, corrosion-resistant materials that provide
long life, and easy cleaning. By following the instructions outlined here, you can expect efficient operation with a
minimum of maintenance.
Motor home plumbing can be divided into two separate systems. The fresh water system consists of those
items which are used to deliver water for your use, while the waste water system is made up of the drains and
tanks which store and remove water that has been used.
FRESH WATER SYSTEM
Fresh water is provided from an external pressurized source, or from the fresh water storage tank.
External hook-up
Water provided from outside the motor home is pressurized by the system from which it is delivered. When
you connect your motor home to an outside source, the fresh water tank and the water pump are kept separate
from the remainder of the system by in-line check valves.
To connect the motor home to an outside source of water:
1. Remove the cap from the fresh water inlet on the side of the
motor home and attach one end of the fresh water hose to
the outside source of water.
2. Connect the other end of the hose to the motor home city
water inlet.
3. Turn the outside source of water ON and open the various
faucets in the motor home gradually to clear the air from the
lines. Close the faucets when the water flows freely.
Note : Do not turn the water pump on when using water from an external supply.
To disconnect from the outside source of supply:
1. Shut off the outside source of water and disconnect the hose from the valve and vehicle inlet.
2. Re-reel the hose and reinstall the cap on the motor home inlet.
Fresh Water Tank With Gravity Fill
When an outside source of water is unavailable, water can be drawn from the fresh water storage tank for use
in the motor home. The tank is filled through a gravity controlled water fill spout on the side of the motor home.
To fill the fresh water tank:
1. Remove the water fill spout cap and fill directly to the tank.
2.
Use a clean hose or bucket from a clean, safe source of water.
3. Be sure to replace the fill spout cap after the tank is filled.
Note: Never leave the hose unattended while you are filling the fresh water tank.
