I have a Watts Pressure Regulator N35B and I need to know how to adjust the pressure on it. Which way do i turn the screw on top to allow more pressure/less pressure through? My problem is that everytime I turn the water on, the pipes howl. If I flush a toilet, the pipes howl after the bowl fills and it stops running. I have turned off all water pipes in the house i could get to in order to eliminate it being a loose washer/ballcock…the vibrating/howling definitely starts at the water main and then makes it’s way through the house…any help would be greatly appreciated.
Thanks!
