The kit would have worked if the internal seal were damaged in the body of the unit. I replaced the whole unit with a new Zurn NR3XL valve.

For those repairing an older NR3 model, you need to remove a flat O ring thar is lodged in the base of the housing. You will find it after you remove the old cartrige, otherwise the new cartrige will not seat all the way. This kit also includes a new adjustable screw and nut which is not shown in the photo. Seems overpriced at $66 since the new complete regulator costs $80, but less work than complete replacement.

My regulator had failed (12 years old) I we had full city pressure. Toilet valve singing and the unit would no longer adjust. A few simple tools and 20 min later the job was complete. Just make sure to remove the old orings as they get stuck and may not come out when removing the old unit. Already having a Guage may adjustment easy.

As long as you turn off the water before the PRV it is not too hard to install the new parts. The new spring will likely be stiffer than the old so the length of the set screw will likely be different to achieve the same water pressure.

Very reasonable and about a half hour work. (I am retired, have time to tinker and always like to repair my own stuff).Noticed that toilets were shutting off "Hard/Loud", upon checking water pressure inside house was at street pressure of 100 psi (house should be set for 60-80 psi max.)This indicated that pressure regulator had failed. In that past (when working for a living) I would just buy a whole new regulator and replace it my self (then they were cheap to buy).Now they cost A LOT (sound like my dad now). One day on U-tube saw a guy rebuilding this regulator."I can do that", So I researched and found this "kit", Instruction included and if you go to there website there is even a video how to and what to check if whole unit needs to be replaced.Come people, if you have time to sit on your computer to read this, YOU HAVE THE TIME!

It's much easier to replace the internals on a PRV than the whole thing in many applications. The only reason to replace the whole thing is if for some reason water froze in the PRV and the housing cracked. It is sort of ridiculous how expensive the rebuild kit is, though. Not much less than an entire PRV.Interesting issue, though. They include a rubber gasket that is not shown in the 'rebuild' assembly diagram. This is supposedly the gasket that fits down in the brass valve after your remove the bell and the cartridge, however it is not the same size as the one I removed. I put the new one in, but I could not get the PRV to adjust properly. It kept going to 100 PSI. So, I put the original gasket back in (which was not as wide), and was able to get it to adjust after doing so. Just thought I should warn y'all. Maybe Zurn will read this and respond to the issue somehow.

Opened and removed old regulator parts, cleaned the valve, installed the kit and presto, I have a new regulator. Work as intended.
