I checked my water pressure. It was 100! But after I adjusted it to 60 my water pressure immediately dropped to 20 after opening cold or hot faucet! Is my water pressure regulator is going bad?
I've never heard anything as strange as trying to adjust your water pressure with a tap running, this makes no sense at all.
Turn your pump off, run the water until your pressure drops to about 30 psi, then flip on the pump again and see what pressure the pump stops at. if it's below 45 psi then turn the adjusting nut clockwise until the pump restarts and wait to see what pressure it stops at. If you want 60 psi then just continue adjusting until you reach the 60 psi you're after and that's it. If it won't go up to 60 psi then it could be the regulator isn't designed to go this high and you need the proper one to get the pressure you're after.
While awaiting an answer to the question Tester101 asked in coments, how to do it and what it means when....
To adjust properly:
- unlock adjustment if there is a locknut
- open a faucet and let water run -
- adjust to desired pressure
- lock adjustment if there is a locknut.
- Close faucet, ensure that no other source is using water.
Watch the pressure gauge while no water is being used. If it rises from the set pressure, the pressure regulator is probably not working correctly. Probably, because it's possible for other factors to cause a pressure rise (lack of or failed expansion tank for a water heater, for instance.) But that's not likely if you only opened a cold water faucet while adjusting the set pressure.
