If it is the short brass cylinder type of regulator, it reduces water flow considerably. A better regulator is available that is adjustable and may also include a gauge. It provides much greater flow. They run about $50-$80, but are worth it if you like pressure in the shower.

How much pressure can the plumping system in the TT handle ?

Not sure what pressure your TT plumbing can handle, but the high flow regulator mentioned above will provide more water flow with supply pressures greater than 40 psi than the cheap pressure regulators. Both will protect your TT plumbing from excessive pressure.

There is usually some sort of check valve and sometimes a flow restrictor/pressure regulator right at the city water inlet and they sometimes collapse restricting the flow even further.

If you have good flow to the kitchen sink or the basin then look for problems in just the shower circuit. Strainer in the wall connection or to the shower handpiece itself

No water in fresh tank, no, though you may get sputtering due to the addition of air to the lines.

Parks vary, where I park in the summer 50-60 PSI is common, where I am now.. Double that (YES 100-120 PSI) the house pump, about 45-55.

However if you 1: Fill the fresh tank and 2: use an IN-LINE filter (Which I seriously recommend) the filter may restrict flow enough that the on-board pump makes a big improvement. Also pressure regulators (Very needed where I am now) I have tested several

Standard (3/4 inch brass or plastic cylinder, Female hose end on one end, male on other) 50 psi Static, WIth the shower going I have to look real close to read the pressure it is that low.

"High Flow" Like above but usually has a bright plastic grip on the female end (Camco has wings on the body) Slightly better but not much.

Sur-Flo Mine is old, and likely needs rebuilding but shower took it down to like 10 PSI

Watts 3/4 inch, Older than the Sur Flo, it hit 20 Again I suspect a rebuild is in order however due to damage from frost... Not sure I want to do it.

Brand new ZURIN 3/4 inch

Static: 50 psi
Full flow on outside shower: 50 PSI. No change that I could see.

Some day I'll likely re-build my watts.. Routine repair kit plus find one missing part.. If I find it I will re-test with it. I suspect with a new diaphrham it will perform identically to the Zurin. Perhaps better.

Home is where I park it!
