What should the water pressure be on your home main water valve? I have mine set to 70psi right now, and most of my water is OK but I still have one bathroom that is performing weak. I don't want to crank it up much more.

The house is mostly PEX tube

The city water here is 50 PSI.
Well water is 40-60 PSI.

So your 70 PSI is more than adequate!

are we talking a well? or something else?

Our well tank is set at 40

Many fixtures have flow controls built into them. Like 2 g.p.m. shower heads and faucet aerators. 50 p.s.i. should be plenty. Too much more and you'll be blowing residential ballcocks apart.

The one bathroom with weak performance, is the issue with all the fixtures? Just the hot on one or two of them?

Typical issues: Clogged flow restrictor, riser valve not fully open or impaired with lodged debris (fully close then fully open; if it is quarter-turn operation, leave all the way open; if brass body with rising washer, fully open then close half a turn).

Has the fixture in question always had a flow problem? It could just be a bad fawcet.

My pressure is 125 psi when it enters the house. I step it down to 55 psi. You have some other problem...It's not a pressure problem.

This for the win.
I would be hesitant to crank it up beyond what you have now...

Check to see if that faucet has a screen and if so it might be clogged and need cleaning.

70 static is plenty. Wish I had that! Is it the entire bathroom or just one fixture that is low flow?

Small town ~500 people... Our city water here is week, Im at almost the elevation of the base of the water tower. It usually runs around 35lb, and I have seen it as low as 22 or 23. I monitor it via a gauge at the washer. The local water utility engineer said the government regulations require them had to supply a minimum of 20 lbs. Below that and they have to "fix" it via providing a booster pump etc.

My water also goes off several times a week after midnight while they refill the 135 year old ground level wooden storage tank I Know better now but have been caught in the shower three times by it!
