Valves to operate – Open and close to control water movement in
the lines in coach.
V1= Regulates Siphon hose. Must be closed except to draw
antifreeze or sanitizing solution.
V2=Valve closes line from tank to pump. Will be open during pump
usage.
V3=Valve controls water to storage tank. Valve location is inside of
coach, normally near water pump, on floor, under a cabinet. To
fill tank, attach a hose to city water fill. Open V3 valve, then
faucet to supply hose. Watch monitor panel, do not overfill your
tank. Close V3 valve when done. When drawing water from tank,
open V2 valve. All other valves are to be closed.
On some coaches with water pump and valves in front storage area,
a wood cover has been installed with 2 to 4 screws. To gain access
to components, you need to remove 4 to 6 screws. Cover is there to
protect plumbing parts and not a code requirement.
12-Volt Demand Pump
When water is desired and you are not hooked up to city water, your
tank will be your supply. On your monitor panel is a switch to turn
on the 12-volt demand pump. Energy for the pump is supplied by
the auxiliary battery or converter. The pump will self-prime when
started, supply water, and continue to run until approximately 40
pounds of pressure is achieved. When pressure drops to 20
pounds, pump will restart. Some cycling in pump may occur. A
check valve is built within the pump to prevent water from flowing
into the supply tank.
The pump has a small filter attached on the “in port “ side to prevent
any foreign matter from entering the pump. You need to annually, or
even more often, remove the lower cup and clean it out.
When pump is not in use, turn 12-volt power off at the switch.
Occasionally your water pump may start/stop quickly ( within a
second ). This is referred to as “cycling”. The cause for this annoying
noise may be a slightly open faucet, water saver washer in the end
of the faucet spout, plus other restrictive issues. If pump cycles
every 10 to 15 minutes, there may be a slight water leak
somewhere, check valve in city water fill, plumbing fittings, or
pressure valve in pump.
