SYSTEMS
WATER AND DRAINAGE PLUMBING_______________________
Your KZ recreational vehicle has a complete water system, to carry
fresh water, as well as holding tanks for used water. Each group
has its own explanation along with its own operation.
FRESH WATER SYSTEM_________________________________
Tanks
Water containers are installed in most RV’s to carry water when
direct city water is not available, such as “boon dock “camping .
These tanks are located under floor, between main frame rails and
steel bars to support them, on the bottom side.
All water containers have 3 exits lines, (1) to draw water from tank to
fill lines, (2) external spigot to drain tank, (3) over flow line, see B-2
below.
Filling Fresh Water System
To place water into your coach’s fresh water system, use one of the
following methods. Different fresh water entry’s are used depending
on model and floor plan.
A. City Water Fill. See Figure 1
1. Water is received into the system through a direct
hookup, referred to as “city water fill”. Attach a
hose to the hook up and supply line. Open the
faucet from the supply line. Enter the unit, and
open any faucet, to allow air to escape, as there
will be some air pockets.
B. Gravity Water Fill. See Figure 2
1. To place water into the fresh water tank,
remove cap from fill. Insert the garden hose into
1-1/4 inch flex tube 4 to 6 inches. Open the
water supply faucet.
2. On gravity water fill, you will find a small screen,
1/2 inch at the 10:00 o’clock position, which is the vent and
over flow line from tank. When water squirts out of this screen,
stop filling tank immediately. Over flow line is much smaller
than fill line. Plastic tank will not accept pressure.
