I am looking at a water pressure regulator that is factory preset 40-50 psi.Does this sound like a good choice.

NON SUFFICIENT INFORMATION. So I'll give you regulator 101.
Regulators come in several types and sizes

Common ones sold for RV use (JUNK) this is a 3/4 inch cylinder with male hose fitting on one end and female on the other, non-swivel female end, solid brass, or solid plastic it is not capable of 1GPM flow rate and will seriously restrict the flow of water. Symptom, you first turn on the faucet water flows well but slows to a trickle.

HIGH-FLOW: like above but with a brightly colored grip on the female end, Camco's has wings on the body.. Slightly better, but still junk for the most part.

Sur-Flo.. This is the one that is built into many motor homes. If it is not part of your water inlet then it is kind of a retangular plastic thing Held together with 4 screws. it too restricts flow but not as bad as teh ones above.

Watts, Valterra or other "Whole House" type regulator, These big brass assemblies generally cost in the range of fifty dollars and up.. Valterra has a knob and a pressure gauge, the rest have a BOLT that sticks up out of a bell shaped houseing. They may or may not have a guage.. I recommend (Other than Valterra which comes with hose fittings) at least 1/2 inch, just bought a 3/4 inch (it was cheaper than the 1/2) They work very well..

Still. Here is what I noticed.

Sur-flo, dead locked on 50 static, but when I turned on the shower, 10 PSI.

Watts 3/4.. 50 static, 20 shower

The new one (Brand not known at this time) is a Watts-a-like, My sense is it will be higher pressure but i will test later today.
