Homeowners need pressure reducing valves

“I have a pressure issue, if the washer machine is filling up, the pressure in the shower reduces to almost a trickle. Same if someone is washing dishes. We had called a plumber at one point, he asked me to borrow a screwdriver and he loosened or tightened the screw on the…”
“I’m stumped on what reading to go off. I have a gauge off one of my lines for the floor heat that’s reading around 30psi which would be the very top end of what it can be. However the gas boiler is reading around 8psi which would be very low. This is my first year owning the…”

Multiple posts indicate homeowners are experiencing high water pressure, leading to potential pipe damage. Several plumbers recommend installing a pressure reducing valve (PRV) to prevent issues and ensure compliance with code (80 PSI max).

“Relatively newer homeowner, so forgive my ignorance here, but I discovered a leak at the adjustment bolt of the pressure relief valve right off the water meter coming into our house. We have fairly hard water here, so I’m imaging that the valve has just…”
“I am completely at my wit's end with our home's pressure reducing valve (PRV) and the local plumbing companies in our area. We are currently facing the prospect of replacing our PRV for the third time in less than two years. To be clear, my husband and I are not plumbers. We are just homeowners going off of what we’ve learned from the various plumbing companies we've worked with and our own research online to try and make sense of this. For context, we bought our house in April 2024”

“I have a pressure issue, if the washer machine is filling up, the pressure in the shower reduces to almost a trickle. Same if someone is washing dishes. We had called a plumber at one point, he asked me to borrow a screwdriver and he loosened or tightened the screw on the pressure reducing valve. Our home is 25+ years old, I figure the rubber in the valve is perished. I see screws on the head of the valve, can I simply rebuild it? Or do I have to call a plumber out to replace the whole thing? &#”
“I just fixed a leak in my main line, and while digging, I found two pressure regulators on the sprinkler line. One is above the ground, and one is underground. Do you see any reason for that? Do you think I could remove the underground regulator to keep a straight line and just use the one above ground? The underground one is quite rusted, and I am afraid it will break down soon. If it is not needed, I'd remove it. Thanks in advance for any thoughts on this! submitted by /u/Signa”
“Apparently it's low before it reaches the system/unit, which typically requires at least 40 PSI [re: Low PSI (< 40) after installing a RO system]”
“Which valve/where are you proposing to put back flow preventer? Appreciate it [re: Water lines are getting too much pressure after regulator]”
“I had an automatic water shut off valve installed and it keeps triggering due to too much pressure 110+ psi). I had a Watts regulator installed and set to 60-65 to regulate town water and it seems to be correct, but within an hour or two water pressure creeps up. I believe it is related to my heating system and hot water storage tank, as I've always noticed a surge of pressure when I return home after being away or in the morning. The pressure is not new, only now I have a measure with the a”
“I had a PRV installed in front of our house between the sidewalk and curb (in grass). Our pressure was 140 psi according to a gauge installed on the hose bib! - They cut my cable and telephone with a shovel - and when I went out to check they acted as if they couldn't see two cut cables near the top of a 1'x1' hole when I asked if this could be why my internet wasn't working - In a separate spot they broke the telemetry device that mounts inside our water meter - They said the pr”
“Your domestic water in a house can’t go over 80psi per code. You will be fine. [re: 200 PSI PVC in softener installation]”
“Don’t leave it based on hope. If the pipe is genuinely rated 200 PSI and your supply can reach 450 PSI, it’s undersized for the system. The pressure tank doesn’t make that safe unless a properly sized, functioning regulator limits pressure downstream. Replace it with correctly rated material and verify pressure with a gauge.

“Water coming into the house was at 90 PSI, so I added a PRV to drop it to 60. Also added a Pressure Relief Valve that'll kick in at 75 PSI in case the PRV fails. submitted by /u/MASSIVE_Johnson6969 [link] [comments]”
“Yeah, your home needs a pressure reducing valve. I've seen supply lines blow out from too much pressure. Code In the US says 80 PSI max. [re: Pressure Gauge acting strange]”
“Yeah on a new gauge. I would trust it. The fact it’s leaking actually probably gives you a better reading because it’s bled out and air that could be trapped and causing extra pressure. You could use a PRV [re: Pressure Gauge acting strange]”
“I took a photo of my pressure gauge reading to send to our condo board president. I thought we needed a pressure regulator. I just bought the gauge yesterday. But I took a video of it today because it seemed to skip, jump and stop. Can I trust this reading? Hopefully this shows the video I took. submitted by /u/Nervous_Ride8954 [link] [comments]”
