    Hi Sabir...

    Pressure reducing valves (see image) are adjustable. Simply spin the screw on top clockwise to increase pressure... ;)

    Check out this video for more info.:

    Great vidio Mark. I would only mention that he never mentioned having a little water running on the downstream side when lowering the pressure. You could turn that sucker counter all the way and the pressure wouldn't drop unless there were some flow right? ;)

    Great point Lee! Hey, it's not like many plumbers actually install a pressure gauge on each side of a PRV either, huh? :cool:

    For sure, homeowners are going to need to run water to check high and low pressure changes!

    At a minimum, as you know, homeowners can track the adjustments using a hose-bib pressure gauge (see images) on an outside faucet. Best is the two pressure gauges as in the video, of course, and it was important to mention all this, Lee, so nice catch!

    Thanks!
