pressure relief valve broken ?
 
I can "fix" my low water pressure by screwing in the set screw on my pressure relief valve. Does that mean its broken ?

Most likly, got a picture of it?
Not much to them, most can be rebuilt.

Is the valve bad ?
 
thanks for the diagram

What I had done is "turn the adjusting bolt clockwise
to increase pressure" This allowed the water pressure to return to "normal". Was my need to do this an indication of a bad valve or a lower city pressure?

Adjustment
Regulator is factory preset to 50psi. (346 kPa) To adjust pressure
setting, loosen the lock nut and turn the adjusting bolt clockwise
to increase pressure, counterclockwise to decrease pressure.
Caution:
Any time a reducing valve is adjusted, the use of a pressure

gauge is recommended to verify correct pressure setting.

That doesn't indicate it is broken but does indicate it is working as designed in most instances, although they can often function fairly normal with a broken spring. When adjusting, I was taught to make the final adjustment on the increase.

For future reference, you have a pressure regulating valve. Pressure relief valves are constructed different and serve a different purpose.

Good luck with increasing your pressure.
