Water Pressure Regulator - Two Questions

Finally bought a 'real' pressure regulator that has a gage and is adjustable. The gage is oil filled and directions are to keep it upright when in use. Straight up and down is not possible with direct connection to most water bibs, so the question is how upright is upright? Does the vent on top of the gage have to stay above the air bubble visible below it, or can it be above the oil?
Next question...for those of you who can adjust your water pressure...how high do you set it? My owners manual says not to exceed 45 psi or the warranty is void. Warranty is out of date and manufacturer is out of business so that doesn't matter anymore. Question is what is a practical safe upper limit?

That is correct. When the flow stops, the pressure will be the same on the output side of the filter.

Took me 3 gauges to figure this one out.

Then the water hose and any filters in-line are not protected from high pressure with regulator at RV.
Is it time for your medication or mine?

Hard to imagine why anyone would want to reduce pressure to less than maximum their RV is designed to handle. INCREASING pressure above that level when source is low pressure won't increase water pressure at all so not sure what the adjustment would do for you.


Mainly because the 'fixed' pressure regulator are set at 45#
With an adjustable one you can choose what pressure set point you want to use......30, 45, 50, 55, 60..whatever you are comfortable with.
And with an adjustable regulator......chances are it is re-buildable if needed

----------------------------------------------------------------
Also, I have been told by someone who knows that the typical cheap in-line regulator restricts flow as well as reducing pressure.


I personally have always called the cheapies a water reducer,never a regulator..jb

If you want to make it even more vertical, Get some garden hose elbows.

30, 45 and 90 degree, Given one of each you can dang near turn === to ||

Set your regulator at 50psi static (no flow).
Is it time for your medication or mine?

Any thing close to vertical should be good. Mine is at a slight angle and have never had a problem. I would think upside might cause a problem. 🙂

Bob - Like your rationale. Since I do have a couple of canister filters after the regulator 50 psi makes sense.
Had been thinking about an Oxygenics shower head and your recommendation just tipped the scales in its favor. Thx
