PRV - Zurn Wilkins NR3XL Leaking from Adjustment Nut

[ProxyBox]

Hi. I have a 1 1/4" Zurn Wilkins NR3XL PRV that's about 6 years old. I recently noticed my pressure rise on my bathroom faucet and after checking it was at 80psi. Previously it was set at 60 psi and held without issue. I removed the bell and noticed the diaphragm, spring and spring retainer were rusty and water leaking at the adjustment nut. I cleaned it up, added some silicone lubricant to the gaskets and reassembled. Everything seems to be holding now but I'm concerned it's going to fail soon. Should the void in the bell be bone dry if working properly? I'm assuming if there is moisture, which is causing the rusting, one of the gaskets is failing. I'm disappointed because I thought the PRV would last much longer. What are you experiences with Zurn PRV's?

I also have a 3/4" NR3XL serving my sprinkler system which was installed at the same time and it also is leaking the same way. When I removed the bell it was actually in worse condition so I went ahead and bought a new one and replaced the cartridge assembly.

Ive got the same 1 1/4 lasted about 3 years so i rebuilt it to save a few bucks my area the homes were built between mid 90s and around 2008 . if the regulators havent been changed then most of them are bad. no opinion as to whether zurn is worse or better than others.

Thanks. I was aware of the repair kits but I found a complete unit for less money on Overstock. Pretty sweet. I think for the 1 1/4 I'll buy the repair kit since it's much less than a complete unit. Appreciate the response.

3 years! That seems pretty low for a device that's passive. When I took mine apart the screen was clean so it's not a debris issue. Also my street pressure is about 100 psi so nothing insane and well within the 3:1 ratio they recommend. I can't imagine most homeowners noticing pressure changes and calling for help to get it fixed. Most probably don't even know what the device does. Ranting but I wish these were engineered better to last. The dial cap Brauckmann prv on my mothers house has been on there since 1992 and hasn't had an issue. Geez.
