It has a union on each end. The inlet at the body is also threaded, so you can use both unions or one union or neither. I replaced a Wilkins model 70 which had worked well for 30 years. The Wilkins 70 had a union at the inlet and the discharge pipe threaded right into the Wilkins. This regulator is the same size as the Wilkins model 70 but about an inch longer if you install both unions. Since my piping has some slack, I installed both unions, but I could have used one union and screwed the discharge onto my exiting piping to make it the same length as the Wilkins. My water hammer and pressure surges are now gone. I looked at rebuilding the Wilkins, which isn't difficult and restores it to new condition, but a rebuild kit costs more than a new regulator. Moving production to China undoubtedly increased profits for the manufacturer since they no longer pay taxes, but the move tripled the price of rebuild kits so now it's cheaper to replace tan rebuild. **Q: Is this one repairable? Our pressure regulator fails every 3 years. The plumber says it's because our water is acidic and it eats them up.** A: Maybe invest in a system to neutralize your water so you dont have to pay for valves every 3 years and the high cost of plumbers fees.Surely its also tearing up your valves in everything you have , showers , faucets , toilets and such if water is that bad. Remember thats also going over your skin... **Q: can it use in the hot water systems?** A: This should be used on the water coming into your house to reduce the pressure from the city to something that your house and its fixtures can handle. The city supply is >100psi, and you want to reduce that to around 60psi so you don't damage your pipes/fixtures. Mine is right before my gas water heater. **Q: How do i know for sure inlet and outlet Dia.1" not 3/4"?. Because hate to return** A: Measure copper tube OD, the actual copper tube is 1.125 in OD (for 1.00” nominal pipe size) or the valve size stamps on the valve ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by L***S on 1 December 2021* All it’s good; worked for the purposed that I bought for. Control the water pressure and hammering pipes ### ⭐⭐⭐⭐⭐ Review *by A***R on 12 November 2020* 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. ### ⭐⭐⭐⭐⭐ Review *by G***Y on 28 November 2025* Fit perfect to replace valve from a different manufacturer. Turned off water at meter, remove old unit, install new with included rubber washer/seals. Check overall length in fitting to out fitting @ 5.5 inches (13.97/14cm). Order your correct size of existing valve (3/4" or 1") marked into valve body, and the swap is DIY friendly with minimal skills. Lefty loosey, rightey tightey and have drip bucket to catch the run off in plumbing when opening the fittings. Great replacement and controlled city pressure entering home perfectly, was over 100psi! Purchased separate gauge to check pressure at outside hose bib/faucet. Over 100psi on old valve, set new valve to 60psi.....Recommend and would purchase again 100%! ## Frequently Bought Together - Zurn Wilkins 34-NR3XLDU 3/4" NR3XL Pressure Reducing Valve with Double Union FNPT Connection - CARBO Instruments 2-1/2" Pressure Gauge,Water Pressure Test Gauge, 3/4" Female Hose Thread, 0-200 PSI with Red Pointer - SENCTRL 0-200 Psi Water Pressure Gauge Test with Lazy Hand, Lead-Free, Waterproof, 2.5" Dial Size, 3/4" Female Garden Hose Thread, Stainless Steel Case, for Home Potable Water, House Tube --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/92356118-zurn-wilkins-34-nr3xldu-3-4-nr3xl-pressure-reducing-valve](https://www.desertcart.vn/products/92356118-zurn-wilkins-34-nr3xldu-3-4-nr3xl-pressure-reducing-valve) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-12*
