City water pressure gauge settings

I also have an adjustable regulator and I set it at 55 lbs because that is also the capacity of the onboard pump.  That being said, I rarely use the city water connection.  I use the pump and fresh water at least 95% of the time, because when I would use the city water connection, I always forgot to turn off the water supply when leaving the trailer for any period of time.  I would also like to know if the pump failed as soon as possible.

I set mine at 60. Normally it read lower at most campgrounds, but OTH I have seen it showing 60 at a few, so there are indeed campgrounds with higher pressure. Be aware that a place with 40 psi can still have extreme pressure spikes, which an old fashioned RV "regulator" (flow restrictor) can't stop. Your adjustable one with gauge can handle those. I have a test gauge for home use, it has a red needle that stays at the maximum value, it can be eye opening to leave that on your faucet for a few weeks. My house pressure is pretty low, normally about 40-45, but that needle has been much higher .

I used to keep my pressure at 60+, which I think is fine - you could probably even bump it higher without worrying.  The plumbing should be fine up to 90psi or higher.  But my advice is to keep it as low as possible while still getting a decent shower, just for lower water usage while boondocking rather than anything else.  After doing some water saving mods with different faucet aerators and shower head, I lowered mine down to 40, since below that point is where the pressure at the shower began to fall noticeably. I set my regulator for city water at 45.  I did have it at 40, same as the pump, but I do get a little nicer shower with 45psi - above that I don't seem to get any additional pressure at all from the sink or shower.  I never tested different pressures with the original plumbing, so I can't say what yours would be like, but I'd say just experiment and see.

We set our city water at 45, also, though we rarely use it.

Since mine is set a 45 and I have had no problems with that pressure, I think I will just leave it there. Our last camping grounds we had 41 there which got me to thinking about water pressure, so that is why I asked the question.

With all due respect, 90 PSI is too high for any home or RV water system without risking damage to the components.  65 PSI is the usual recommended safe maximum.  As Overland points out, around 40-45 PSI is best if that produces enough pressure for normal use.  But I would not recommend ever going above 65 PSI.

I set mine to 55# witch is the rating for the on board pump. BE CAREFUL when first hooking up, make sure that you do not have air in your water system. Open the hot and cold water valves in the trailer and Slowly open the water supply valve until there is no air.  This will help eliminate water hammer that can compress air in the system greater then it is designed for and cause problems.
