Residential water pressure


My parents have 180 PSI coming into their house and use a Watts regulator to lower it to 50 PSI. One shower by itself is...acceptable (to me) but barely. If two people shower at once or one person + a toilet flushing, it's really low.

It is safe to raise the house pressure to..say...80 PSI? If so, how is this done? Tightening the screw on the regulator?

Thanks.

Residential water pressure


usually 60 is good if constant which should be without press tank. 80 might damage fixtures. yes should be locking nut and screw not sure of rotation

You're right, you turn up the pressure by tightening the screw.

I agree with the previous poster, be safest to keep it at around 60psi.

I have a psi meter that hooks up to a hose spigot. This a good way to test the pressure? Any idea how much I'd need to turn the screw to go from 50 to 60 psi?

I have almost 80 here & at the last house
Last house I had a garden house burst
I haven't tried adjusting the pressure down

I think it would depend upon the valve...try it little by little maybe ?

Yeah, I'll just have my dad stand out by the spigot watching the gauge while I slowly turn. My house is about running at about 80 here in my house, but I think my parents will be nervous going that high. 60 or so would be good I think.

Residential water pressure


the pressure on the gauge probably wont change untill some pressure is relieved by opening a valve/faucet somewhere in the system
