SYSTEMS
Water and Drainage Plumbing
Your KZ recreational vehicle has a complete water system to carry fresh
water, as well as used water, in holding tanks. Each group has its own
explanation along with its own operation.
Fresh Water System
Tanks
Water containers are installed in most RVs to carry water when direct city
water is not available. These tanks are located under the floor, between
main frame rails and steel bars, which support them.
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.
Filling Fresh Water System
To place water into your coach’s fresh water system, use one of the
following methods. Different fresh water entries 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
all faucets, 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.
C. During the water tank filling process, check the monitor panel
for filling process (if applicable).
