[VAC] Re: Water Pressure

[John Anderson <janderson@xxxxxxxx>]

Thomas, unfortunately this practice will not protect your trailer from
overpressurization at all.  A throttled valve or similar device only reduces
pressure when there is active flow in the system.  When the flow is halted
at the point of use, e.g. by turning off the faucet in your trailer, the
pressure equalizes all the way from the source through your entire system.
The only result of a throttled supply valve is that it reduces flow and
pressure when you most want it, i.e. when you are drawing water from the
system.  You really need a regulator at the hose connection which will open
as flow is demanded, and close as flow demand is reduced, maintaining a
relatively constant pressure on your system.
