Zurn RK34-70XL Wilkins Repair Kit for 0.75" Models 70, 70DU, and 70XL and for 3/4" Pressure Reducing Valve (PRV) 70 Series

I had a failed pressure regulator that was soldered in to copper pipe. I had planned to replace it, but was not looking forward to cutting everything apart, replacing the junctions and soldering everything back together. I am a household handyman, but serious plumbing is above my pay grade. The kit was not hard to install (you do need to know your way around basic tools, etc.) and works perfectly. It saved me only a few dollars compared to the cost of buying a new regulator, however if you add in hiring a plumber, it saved me a bundle, not to mention saving several pounds of brass from the trash.

Less expensive than replacing the PRV and less disruptive. Replacing the "inside" of the PRV made a huge difference. Water pressure fluctuates much less than before replacing the parts. All parts are and are a perfect fit. Would have cost much more if I had to have a plumber replace the PRV. This is a self replacement with time and patience. Highly recommend

This was a pretty easy replacement. Make sure you have a 1 1/8” socket to remove the cartridge. If it’s super stuck like mine, an impact drill will make quick work to loosen things up. Pretty straight forward. My water pressure was between 80-120psi at various times of the day. And there was a lot of debris and sediment gunking up the cartridge. My water flow was pretty low despite the pressure. I think at the end of the day I could have gotten away with taking out the old cartridge and cleaning it and only replacing the hard-as-a-rock diaphragm, but I went ahead and swapped all the parts out. Only complaint is that the replacement cartridge is plastic. Time will tell how well that holds up.

Great product for repairing my old failed unit. Instructions pretty clear and there's a YouTube video that helps if you're not quite sure. Saved me the cost of a plumber.Two thoughts: your old unit may be on pretty tight, so figure out a way to protect your pipes from the torque when you open up the old bell housing. AND make sure to use a water pressure guage and set your pressure to your local water company recommended pressure. They're available here on Amazon and attach to the outside hose faucet. Piece of cake.

Install only to have it leak.

The kit does work. (+5) The original cartridge is either brass or copper. The new cartridge is made of plastic and stainless steel. I am not sure it can be unscrewed next time as a single piece. (-2) There is lubricant but not in the small tube in the picture. Amazon missed its original delivered date

I was hesitant to remove my existing valve (that was bad). I had two companies come and bid this replacement - one was $700, the other was $1,000.I removed my old valve - it was a bit of work to get the housing apart....existing unit was 25 years old. I applied some heat with a butane torch and the housing came right off. It was a breeze getting the new parts installed and getting the unit adjusted (55 PSI).Old PSI was 130 - this new install moved it down to a much safer PSI. I was intimidated to do this repair but found a really great video online to help.Shipping was fast and the cost was more than 1/10th less than hiring this out. I'd recommend going this route again in a heart beat.

My water pressure was running 120 psi at the faucet and since my neighbor had a pipe burst causing $30K worth of damage and I was having garden hoses bulge with leaks, I figured I'd better get my pressure reducing valve working. Since my Zurn Wilkins 70 is 14 years old, it was time to replace the parts with this repair kit. I watched the video on how to do the repair and the replacement kit worked exactly as expected. My water pressure is now set at 70 psi which I measured at the faucet and I have piece of mind that it isn't going to create a major repair to my home because the water pressure is too high. I've included a picture of the old parts vs the new for comparison.
