PRODUCT OVERVIEW

Model # 1-70XLDUC

Internet # 203999025

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°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

CUSTOMER REVIEWS

Rated 3.9 out of 5 by 7 reviewers.
Rated 2.0 out of 5.0 by Good, but not a good value The ease of installation was great, but the device SHOULD last at about a year (according to HD staff and the plumber who installed my water heater)... on my 4th one now, average life expectancy has been 6 months, making it less and less of a value for the price.

Rated 5.0 out of 5.0 by Perfect drop in replacement This was a perfect drop in replacement for the 15 year old Wilkins unit it was replacing. This meant I only had to undo the unions and slide the new unit it place-- I didn't even have to sweat the new fittings onto the copper. Only had to have the water to the house shut off for five minutes instead of 30 which made the wife and kids much happier. Pricing was middle of the road, but the product was available to be shipped immediately so it was worth it to me to pay more since my water pressure inside the house was 140 psi and EVERYTHING was leaking.

Rated 4.0 out of 5.0 by Efficient Pressure Reducer Valve Installation The replacement installation was a perfect size match for my Honeywell Braukmann making installation go fast as the threading on the PRV matched the existing pre-sweated union. The adjustment range is not fantastic, 25 to 75, and the temperature range is lower than many making a full sun exposure in the southwest a bit daring. This model was designed in 1972, so it has proof of time behind it, and likely a significant "plumbers' trade" discount improving the plumbers profit. Following installation, the pressure was measured by the plumber at 60 lbs, not the 50 lbs as advertised. There is a benefit to this model as it is repairable/rebuildable if you find a plumber that will do that; as I could not, repairability is a "feature" of no value to the non-plumber home owner. FYI California, this valve does meet California's front running plumbing regulations for low/no lead construction. Now, for the acid test, it has held the desired 70 lbs. pressure with nominal fall-off (drop in pressure) when fixtures are in use. We have backflow regulations in our community, so thermal expansion is a problem that my plumber says can be exacerbated (my word, no the plumbers) by a poorly performing PRV. I doubt that, so I also installed a thermal expansion tank. FYI, Home Depot also provided me with the expansion tank (an obsolete model) no longer sold by the manufacturer. January 23, 2015
Rated 5.0 out of 5.0 by Good product Product very easy to install and shipping good on time. January 13, 2015
Rated 5.0 out of 5.0 by Water Pressure Reducing Valve Purchased these units for use at our HOA. They were installed easily by one of our HOA owners that has plumbing experience. There were no complications and the valves have not required any additional attention other than to monitor the PSI. October 7, 2014
Rated 5.0 out of 5.0 by This was hard to fine and Home Depot had it Plumbing supply only had single union which would of meant digging out my main line, in my case. Getting the double union saved me lots of work. ++ October 7, 2014
Rated 1.0 out of 5.0 by Easy Install I like how easy it is to install. However, the product I received may have been defective since water is still dripping from the shower head and faucets. June 17, 2014
