How many turns on Pressure Regulator?

removing and cleaning strainer. I assume one should shut off water before --and after-- regulator and put a deep dish under assembly to catch water coming from both directions.

Watts 25AUB-Z3 on house 3/4\" CW supply

Town just put in new water mains; perhaps that's why my sprinklers don't move anymore due to decreased pressure. Or maybe everyone else is sprinkling due to drought. Anyway I turned the top nut clockwise about 3/4 turn with a slight change in sprinkler. About how many turns per how many pounds of pressure is there? I will buy a pressure gauge when I can.
Factory is preset for 50, but I think in the past we set it for 60. (I notice regulator was installed before the water meter, after the shutoff.)

Thanks,

David

You need a gauge to set.Any thing else would be a guess.....

Big Ed's

right. The number of turns is relative to incoming vs. downstream ratios, there is no p.s.i. per revolution "standard," since it is more a ratio than a "known" end result. And, since incoming pressure will vary based upon upstream use, temperature and pumping station variants, no reliable ratio can be established.

Thanks much

Sediment and debris

normally after water lines are worked on a bunch of crud will get stuck in the screen on the inlet side of your pressure reducing valve; causing a low flow (volume) which may seem like a lack of pressure.

This

can be a delicate task David and if you are not careful putting the plug back you could end up with stripped threads and a leak.

Are you sure it needs cleaning? The best way to tell is when you turn on a high volume faucet (outside faucet, tub spout), the water comes out fine and then drops off quickly.

You could be having a low pressure problem but not necessarily a volume issue that dirt in the strainer would cause.

Getting a gauge is a good start.

i think you're correct

there is no problem as you describe and I should just get a gauge with a hose cock adapter and check it. And ask the town if they've changed pressure. There's alot of draining going on as they clear the system. Brown water's been a problem for years in this side of town that perhaps new mains are not going to solve.

Only real pressure problem I have is with the sprinkler oscillators--though slightly noticeable drop in the shower too. But probably good to get a plumber to service the regulator annually. The only leaks I know about here --from myself and previous owner-- have been the regulators. thanks for the good advice.

Sorry, but it's ZFriday.......;-)

When I saw the post of how many turns,...The first thing I thought of was, How many licks did it actually take to get to the center of that darn tootsie roll pop??? Did anyone ever figure that out? ;-) Also is that Owl still living???

Mike T. Have a great weekend guy's///////////

Watts builds a gauge that screws

onto a hose bib. Very easy to use on any bib or water heater drain. It also has a "lazy" or floating hand to record pressure spikes.

Most plumbing supply stores have them on the shelf.

First check the static pressure with no water flowing. then start opening faucets and observe the pressure. This will help determine if you have a flow restriction somewhere.
