RV fresh water system
The typical RV fresh water system is a combination of advanced technical accomplishment balanced
by the economic principles of profit and loss. The manufacturer desires a functional water supply system at a
"cost effective" level, and generally this is the case.
Modern RVs are equipped with pressure demand type automatic pumps,
polyethylene fresh water storage tanks, and polybutylene water lines. The various and innumerable joints and
connections are of the compression ring type which are very quick and economical to assemble at the factory level
when everything is exposed and in the open.
These systems are designed to be operated at a certain maximum water
pressure level in the neighborhood of 35 to 45 pounds per square inch. The on-board pump has a built in pressure
switch that shuts off the power to the pump when this pressure has been reached. So far, so good, and everything is
as it should be.
However, (and there always seems to be a "however"), there is a city water
connection to supply water at home or at the RV park via a hose connection. Often, the pressure at these
facilities, exceeds 80 pounds per square inch or more, sometimes much more, in certain situations. This high
pressure can and does cause leaks to develop where none had come before and by the Law of Murphy, you are either
out to dinner or it's 3 in the morning.
A simple device is available and necessary for your peace of
mind. A water pressure regulator should be used whenever connecting to an
outside water supply source. This device controls the incoming water pressure to supply a continuous and
regulated 45 PSI maximum. It is connected at the supply end of the hose to protect the hose and the RV at the
