Frequently Bought Together

Product Overview

The Zurn-Wilkins Model 70XLDUC is designed for installation on potable water lines to reduce high inlet pressure to a lower outlet pressure. The double union female copper sweat connections makes this device most suitable for applications with minimal clearance and installations requiring frequent off-site maintenance. The direct acting integral by-pass design prevents buildup of excessive system pressure caused by thermal expansion. The balanced piston design enables the regulator to react in a smooth and responsive manner to changes in system flow demand, while at the same time, providing protection from inlet pressure changes.

  • All bronze body and bell housing provides durability and long life
  • Built-in by-pass prevents buildup of excessive system pressure caused by thermal expansion
  • Maximum working pressure rated 300 psi, maximum working water temperature 140 Degrees F
  • Spring range 25 to 75 psi; factory set at 50 psi
  • ASSE listed 1003, IAPMO listed, CSA certified, city of Los Angeles approved, NSF listed, standard 61, annex G

Answer: 
If I understand your question (is down for more pressure? thru the valve), then yes, if you adjust the bolt (with lock nut) which extends outward at the point of the pressure regulator inward (loosen the lock nut and tighten the bolt), you will increase the allowed outlet water pressure.
I will offer that on my previous water pressure regulator, I adjusted the bolt all the way in, to allow maximum Read More
If I understand your question (is down for more pressure? thru the valve), then yes, if you adjust the bolt (with lock nut) which extends outward at the point of the pressure regulator inward (loosen the lock nut and tighten the bolt), you will increase the allowed outlet water pressure.
I will offer that on my previous water pressure regulator, I adjusted the bolt all the way in, to allow maximum water pressure out (75psi) and over time (several years), that outlet pressure was up to 85psi, and led to me needing to replace the pressure regulator.
In my case, I concluded that over time, the inner workings of the pressure regulator failed (or simply wore-out) and thus allowed more than the maximum pressure through. It also got to the point where any water use in the house caused a noticeable whistling from the pressure regulator, which my plumber told me was a sign that the regulator was failing & allowing too much water pressure through (also verified with a pressure gauge which indicated 85psi). Ultimately, no more than 75psi should be allowed into a home, as water pressures above 75psi can cause damage to plumbing fixtures (or things like the water line to refrigerator) over time. Read Less

Answer: 
Hello scott,
You are correct. After loosening the lock nut turn the stud clockwise (down) to increase the pressure. I hope this helps.
Cheers,
Chris

Answer: 
Well, I suppose you could have a gauge installed in-line, but the normal size of water pressure gauges and the pressure regulator do not match, and thus do not lend themselves to simply connecting to each other.

Rated 5.0 out of 5 by 6 reviewers.
Rated 5.0 out of 5.0 by Great upgrade if you need to replace your home water pressure regulator. Had this water pressure regulator professionally installed and now I can replace it in the future myself! July 19, 2016
Rated 5.0 out of 5.0 by Good Valve and Good Experience with Home Depot My old PRV was in bad shape - small leak, and very annoying "whooshing" sound whenever we ran water anywhere in the house. Sought this valve out since it has a double union connection. I couldn't find this in my local Home Depot or the Blue Box either. Fortunately, ordering it through Home Depot online was hassle-free. Installation was fairly easy, if you know how to sweat pipe joints. I'm no plumber, but I've done enough of this that it wasn't bad. Now that I have the valve installed, should it ever go bad (God forbid), all I have to do is break the unions open, pull out the bad valve and put in a new one. The ordering process with Home Depot was a piece of cake. I'm very happy with how this whole process went. May 24, 2016
Rated 5.0 out of 5.0 by Excellent Product. Easy to install I had viewed several YouTube videos on how to install the pressure regulator, and when it came to do it, it was a breeze. The installation took a couple of hours, only because I did a poor job of sweat soldering, and had to repeat soldering i union 3 times. When I finally got no leaks, the unit worked as intended and immediately dropped my water pressure from 110 pounds to 50. The only negative comment I have is that the installation instructions are non-existant, and the unit comes only with instructions on repair. September 1, 2015
Rated 5.0 out of 5.0 by Great product Very easy to install with the two sweat fittings and the double union. I'm also impressed with the apparent quality of the valve, specifically I like the bronze cap this one has rather than the plastic or steel tops that are on many of the alternatives. May 4, 2016
Rated 5.0 out of 5.0 by Best one out there This one is easy to service and comes in double Union so easy to get in and out. Home deport had this in stock in store April 15, 2015
Rated 5.0 out of 5.0 by Fast and easy This valve just about installs itself. You must of course remove the old one first. September 8, 2015
