Zurn Wilkins Double Union Female CU SWT Pressure Reducing Valve

If you have a situation where you need to heat this up at the union with everything screwed together, and you want everything straight, you risk melting the rubber gaskets. If you remove the gaskets, you'll be off in your lengths. What I did - worth sharing and should be in the instructions IMO - is to stack both gaskets on one side, solder the other side. When this cools, swap both gaskets over to the side you just soldered and do the other side. When all is cool, assemble normally. This worked really well and the whole thing is perfectly aligned. All caveats for soldering a brass valve apply - heat the pipe more, the female fitting less, wrap the valve body in wet towel, etc. Hopefully in 10-15 years when the life of this thing is up, they'll still make it and swapping a new one in there will take 5 minutes.I first tried to rebuild my old one, a Watts 25AUB, but what happens is the brass gets pitted and corroded and nothing inside seals anymore - waste of time and money. A Watts 25AUB lead free with 2 solder cups is hard to find, so I bought this. I also noted the pressure drop specs for this valve are much better than the Watts - 5.5 psi vs 12.5 psi drop at 10 gpm. We'll see long term.

We are gifted with 110 PSI water pressure at the tap. When I repiped the house with 1" copper, I noticed the very annoying sound of water flow in the downstairs bedroom ceiling it runs through. I tried quieting it with extra thick foam pipe insulation, commercial grade Holdrite style acoustic pipe isolators, and even a suspended ceiling. I planned to go back and increase the pipe diameter in that particular room just to slow the flow, when the helpful folks at the Terry Love plumbing forums suggested I check my water pressure.If you can solder, and have access to about 6 inches of straight copper where the water service enters the house, you can install this in not much time. The only potential "gotcha" is to make sure you put the two nuts on the copper before installing / sweating the two large brass flanges that seat the valve. Other than that, it's about as straightforward an installation as it gets. Mine came preset at 65 PSI, and that's exactly what my pressure gauge read when I checked after installation.

Replacing a NR3XL which was 5 years old but would not hold the pressure. The biggest telltale was you would set the running pressure to 60psi and the static pressure would drift +20psi to 79/80psi consistently. I would not have known this without having a Flo by Moen installed.The 70XL drops 2-3psi when running which is acceptable. It’s so far been maintaining static pressure and was a 5 minute swap for the existing NR3XL

I ordered this to replace an existing model 70XL with single union. I suspected it had gone bad because all of sudden we had poor water flow in the house but the pressure relief valve kept leaking. I used a water pressure gauge on one of the bibs inside the house and pressure was just over 100 PSI !! This could have really damaged our pipes so thank god for the relief valve. I replaced our old regulator with this product and, used my gauge to check my new pressure. The manufacturer states the regulator is set to 50PSI by default, and this is exactly what my gauge was telling me-- it works works perfectly now. No pressure issues and we are back to enjoying showers with proper water flow.

My water pressure was 108 psi before I installed the Wilkins pressure regulator and now I have my pressure set at 60psi. The regulator comes preset from the factory @ 50psi but I wanted a little more than 50, so turning a screw took about 2 minutes to adjust to 60psi. It is well made as a bronze casting and this particular one has a union at both ends which facilitates adding/removal easily without having to remove other pipes/fittings. Can be installed in less than an hour.

Love the double sweat union. I've had issues with bad threads on big box store copper. Skip those sweat right to the brass and there's no worries of leaks.

This unit was exactly as advertised. I had trouble finding the sweat fitting till I went on Amazon.

Great pressure reducing valve for the money. Well made!
