pressure reducing valve

Hi all, I'd like some insight here as I have been going back and forth with the local municipality to shut the water off so I could at least sweat the old gate valves off in order to do a repair on a slow leaking pressure reducing valve but they are claiming this is not an emergency and may get...

Hello, We have a summer cottage in upstate New York that gets winterized every season. We just did a major remodel and had a plumber install all new PEX and a new water heater. At the same time, the town also ran a new water main and it now includes a backflow preventor. The pressure relief...

This was from my reddit post, but I am not getting any responses so hopefully I can find some help here! Here is the original post for my water boiler (Utica Boiler Model number MGB-100J): In the summer I removed a radiator from my house in order to reinstall flooring. I refilled the system and...

Hi. Newbie here. I've searched for help on this topic all across the Internet and I couldn't find anything. So, I thought I'd ask the pros. I have pipes at the main that sometimes violently vibrate / chatter. This seems to happen during medium to heavy flow. Here's my setup: Water comes up...

My water softener got fried (because of a dumb mistake) and before putting in a new one I decided to install a whole house filter and bypass loop to tame the chlorine. Part of that loop includes some pressure gauges and I found that our pressure is pretty steadily 80-85psi on city water. I...

Hi, I would like to pressure test my PEX system before use. It seems this is often done with air. I found a hose fitting with a Schrader valve and my plan was to use my bike tire pump which has a gauge on it. The system also contains a gauge, as well as a pressure reducing valve with an outlet...

I am attempting to replace a pressure reduction valve where the water comes into the house from the city. Water pressure at the spigot was measured at 140 psi. I bought a replacement valve of the same size but different brand. When I went to replace it I ran into a big problem. The connections...

How often do PRV's get replaced in a home? Good question. Sometimes when they fail to reduce pressure. Replacement or new parts at that time, assuming you have the parts. It's normally easier for a plumber to show up with a new PRV and just replace the old one. Time is money you know. And can...

Shared well will be closed March 1st by neighbor as a result of water sample result. They won't consider shock/ chlorination. Installation of new city water line starting next week. (January in Indiana) Meter will be at top of driveway 1,800 ft from my home. Have shutoff valve outside. Main...

I'm at a loss - I've tried everything I can think of, so its time to turn to the experts. I've attached a rudimentary schematic to help you understand the general layout of things. My House is up on a hill, so the street (including municipal water) is probably 15-20 vertical feet below the...

Hello! I need a pressure reducing valve as I've just discovered that my service line clocks in at around 95 psi, which I believe would explain a couple of (cheap) garden hoses blistering. I called around the local plumbing supply stores and was quoted a pretty consistent ~$300 (Canadian) for a...

Hi again all. I installed a new expansion tank (ET) which I pre-charged to 55 psi. After installing the ET, and with the WH off, I still have 120 psi static which drops to 90 with a tap opened to low flow; it returns to 120 psi in 2 mins after closing the tap. It drops to 55 within 2 mins of...

Thanks in advance for your help on this! I've had a leak in a pressure relief valve coming off the boiler that is now being used only for DHW. I changed the relief valve, but it still leaks. So I'm now thinking about looking at replacing the system's pressure reducing valve (taco 329-3), since...

We're selling a 3-year-old, new-build home. We've never had any plumbing issues and had several inspectors look at the house both as a buyer, and now as a seller. The current buyer's inspector identified that the water pressure is too high (about 100psi), and the buyer required installation of...

Hello, while my water is running and for a time after I turn it off my pipes knock quite a lot (sometimes even just in the middle of the night). I'm wondering if it's the PRV because the downstream water pressure is set to 60 and will go to that after I turn the water off but will rise back to...

According to Canadian NPC, provision must be made for thermal expansion when check valves or pressure reducing valves are installed. Is the T&P relief valve sufficient to meet this requirement? Or must an expansion tank be installed. I always install an expansion tank when check valves are...

For two weeks now, our house water pressure oddly drops briefly, then returns to normal. This started after returning from a trip (about a month of no use). Video (https://tinyurl.com/y9oybl5c) We have city water. About 1 year ago, we called a plumber to adjust our low water pressure; the...
