Last updated on August 1, 2024 12:30 am Details
- Designed for installation on potable water lines to reduce high inlet pressure to a lower outlet pressure
- Integral strainer makes this device most suitable for residential and commercial water systems that require frequent cleaning of sediment and debris
- Direct acting integral by-pass design prevents buildup of excessive system pressure caused by thermal expansion. Maximum Working Temperature (F):180
- Balance piston design enables the regulator to react in a smooth and responsive manner to changes in system flow demand
- Provides protection from inlet pressure changes

Works great. This was cheaper than buying a rebuild kit for my old regulator. Only caveat is hang on to your old regulator. I found that mine was simply plugged with minerals, but REALLY plugged. I had to soak it in vinegar for a week and change the vinegar several times to clean it. Once cleaned, it’s fine. The reason I am saving it is this one will eventually scale up so I can just swap and soak again.

This is a replacement for the BR4 valve which has been discontinued. If you are replacing an identical valve with the double union, it’s a half hour job. Watch a couple of YouTube videos to see the process. It becomes a much bigger job if you need to cut and solder pipe. You can also buy rebuild kits for these valves. They’re not much cheaper than a new valve, but if your installation requires cutting and soldering pipe to replace, a rebuild kit would be a better option and could be installed without removing the valve.
This is the third valve now in a 13 year old house so I question the durability. Both times, replacements were needed after the county replaced the water meter out at the street. Not sure if it’s coincidence or not.
I noticed that the shower pressure dropped noticeably when another family member flushed a toilet. That never happened before. Put my pressure gauge on the front hose bib. Had 100# with nothing running (too high) and dropped to 40# when the kitchen faucet was turned on (too low). This indicates a bad valve. The factory setting is 50#. There’s numerous opinions on what’s optimal but that’s too low for a large house with numerous fixtures. After installation I adjusted up to 60# and see no drop on my gauge when several faucets are open, as it should be. To do this job right, you’ll need a pressure gauge that you can buy here for less than $10 or at the big box store in the plumbing or irrigation aisle.
I deducted one star for lack of durability, also the old BR4 came with a sediment screen/washer for the incoming side and this one only has a washer. I cleaned and reused the old one.

All it’s good; worked for the purposed that I bought for. Control the water pressure and hammering pipes

My household pressure was getting into the mid 80’s after way to long I decided to install a regulator. The Zurn Wilkins 1-NR3XLDU 1″ looked like the correct one. Old one was no longer available 1991. The old one had one union on the inlet side and used a threaded fitting on the other. Can’t understand why the used just one union but have seen this before. I decided to add a union on the outlet side. The unions on the ne regulator were not sweat they were threaded I could not find any information on type of unions in product description that’s why I give it 4 stars. Having extra unions, I went ahead and ordered it. If your piping is copper you would need to use copper MIP’s into the unions. On my installation I was able to just use the existing union on the supply. I had about a 5” piece of copper above the regulator I just cut that in the middle
and sweated the remaining piece out of the tee it went into. The hardest part was getting the solder out of the Tee. I mounted the new valve in the lower union then was able to determine the length of copper need to complete the installation. once I had that figured out, I dry fit everything once I new it was good Pulled the regulator out and soldered vin the new union and copper into Tee. You do not want solder the valve with the rubber gaskets installed your better off to solder the brass coupling pieces before you install the copper into Tee. Also make sure you have the tightening nut on the copper piece before you solder, nothing worse than having to sweat it off. Then I just installed the valve with the gaskets didn’t break my arm tightening it. Turned the water on all was good. BTW sweat & sweating is soldering or unsoldering.
Now How does it work: like charm works like it should. Adjustment: As other mentioned the factory setting 55psi? it was off I was at about 45psi so this was no surprise, your inlet pressure Is going to regulate what kind of adjustment the internal spring is going to need. My house was at 80+ psi I set the regulator at 65 psi ( I have a gauge installed in my system) with a sink running wide open and flushing a toilet at the same time I drop down to 60psi. After taking a shower It feels like I actually have more flow. I’m thinking after opening up the old regulator a pile of rust came out most the “metal” parts were corroding away probably flow was restricted. I’m pleased with the regulator works great, granted there’s always a chance you can get a defective part.
Should you try this yourself? That’s up to you myself being retired from the piping trades I thought it was pretty easy.

Product installed easily and preset as advertized to 50 PSI. Happy customer!

I bought this unit to replace our existing home pressure valve. Any DIY person should be able to install this product as long as they READ the instructions. This was a better unit than the one I replaced and it fit perfectly. No issues on installation, or setting the pressure required.

No problems so far. Works perfectly and is generally what I expected. A pressure gage port would have been useful.

Very good quality it comes with 2 unions which make installation much easier and cheaper if you expect 10 to 20 gal flow this valve could cause too much pressure drop from set point which i had set at 65 psi as soon as i opened the faucet it drops to close to 40 psi check out the video i replaced this valve with 1″ one

Update 2021 – has run for over a year without missing a beat so changing my rating to 5 stars.
Original review’s The device feels pretty well-made, doesn’t rattle or anything. It seems to work most of the time, but sometimes it just stops restricting pressure and allows the pressure into your home system. I have a flow by Moen Smart water device and I’ve included a screenshot showing the pressure raising well above the 70 pounds that I have it set at. in fact it went from 70 to 125 and I’m not sure how much higher it would have kept going had we not turned on the water in the house to release the pressure. I have analog gauges that confirmed this pressure spike. Even the sixteen-year-old device it it was replacing worked better than that, how sad is that? it sucks that I had this on my projects table for a month before I got around to doing the project, it’s too late to return it now. It may just be a single faulty device, or the problem may be systemic with the entire line I can’t tell you because I won’t buy another one from this company.

Good, heavy gauge construction. I like the fact that it has an internal screen to prevent debris from messing up the valve. Should last for many years.
