Water Pressure

Have noticed that at all the campgrounds that we visit, I have higher water pressure on the internal pump than when connected to city water. I always use a pressure reducer on the hose. Water pressure is such that the tankless water heater might need a few tries to turn on, but comes immediately on with internal pump. Water pressure, when set up for boondocking is great. I have resisted the temptation to run a straight hose without a pressure reduction coupling. I was considering bumping the pressure up a bit with an adjustable water pressure coupling with a gauge.
Any and all thoughts/experience appreciated!

Get a true water pressure regulator as you mention - it’s the only way to get a true idea of where to start looking.

Our ‘02 coach also seemed to struggle on water pressure when hooked to the park system. I ended up replacing the inlet connector with the integrated check valve.
They can be serviced but they are a pain to do so. As cheap as they are, you buy a new one, replace, and move on.

BTW - when you get a regulator with a pressure gauge, always read and adjust the pressure with water flowing from at least 1 faucet.

Check your water filter. I had a similar problem and it turned out to be the whole house filter was plugged up. New filter, and all is well!

BTW, we always use our house pump. Just fill the FW tank when needed, and switch back to the pump. That way we always have the same pressure in the rig.

What pressure is your Regulator set for?
*S/B 50# static (or higher)

House filter getting dirty
City Water Inlet Screed washer dirty
City Water inlet Check Valve clogged

Haven't used City Water in over 14 yrs.........pump exclusively
Same consistent pressure/flow regardless of where we are, simple flip of switch turns it off when going to bed/leaving the RV, pump burps--indicates 'leak' etc
