Hi Dick,
In my 1973 Ambassador, there are three valves under the stove, that all
should be shut unless you are trying to get all the water out of the
pipes as in winterizing.
I have the rear bedroom, and under the bed is one faucet. the under the
bed faucet allows the "shore" water to enter the water system. When you
want to use your pump, this faucet needs to be closed.
In my trailer, it is clear that the under the bed water line heads right
for the place you would hook up your hose. So find your shore water
connection and then inside of it, close the next faucet you come to.
Now you have a closed system and the pump can do it's job. You said
there were two faucets in the rear, I don't know about that other one,
unless it is part of a hot water heater by pass set up. You will have
to get up close and personal with the hot water heater's guts to figure
that one out.
You didn't say whether the pump was at least humming and brrrrring and
trying to run. If you don't hear it, then you need to trouble shoot the
pump. There should be a line fuse on its power supply, or maybe a glass
tube automotive fuse. There should also be a sediment filter which you
can carefully take appart ( don't drop the screw down there....) and
clean out.
I only just had to repair my original pump last year, you can still buy
a kit!
