Delta Faucet RP77739 Repair Kit

I bought this because the twenty-year-old bathroom faucet's seals had given out, so it was either try to fix it or replace the whole faucet with a new one. I had already disassembled the faucet, so I felt alright in trying a repair. The faucet kit arrived promptly, and the same evening I set about applying it. I thought perhaps I would need to look online for instructions, but I found an instruction guide was printed with the package label. I looked over the parts, and was momentarily wondering whether I had ordered the right kit, but the instructions mentioned that the part design had changed. They also specified removing the adjustment ring that had the job of keeping enough pressure on gaskets so that they did not leak. I replaced the two small rubber sleeved seals for the supplies and their springs, after doing the recommended cleaning of the ports with a soft cloth. The new ball's post went through the gasket assembly, and all that went into the faucet barrel. I removed the no-longer-needed adjustment ring from the barrel cover, then tightened down the barrel cover. I positioned the handle to midway and slowly turned on the supply lines in turn, verifying no leakage was happening where it shouldn't, then bringing the handle to the closed position and seeing that there was no flow there. That all took me about thirty minutes, and I was being slow and making sure I read the directions because of the parts change. Next time, I think a changeover would take me maybe twenty minutes from starting disassembly to putting the decorative handle cover back on. The newly repaired faucet handle moves more freely, yet does not have any leakage. This is one time where the newly re-engineered solution succeeds brilliantly. It is easier to put together, has fewer adjustments that have to happen, and works better than the original ever did. Congratulations to the product designers.

Ordered this kit to rebuild a single knob bathroom faucet in our home that was built in 1976 with original plumbing hardware. Installation was easy as can be and I also used some waterproof plumber's grease when I reassembled. The faucet works wonderfully-- so silky and smooth now. I loved it so much I decided to rebuild our shower faucet as well but got impatient and ran to Lowes to see if they had this kit. They did not have the OEM Delta kit and I bought the aftermarket brand kit they carried that was similar with the same replacement ball and o-rings. It is NOT the same. I rebuilt our shower with the aftermarket kit and it leaks unless you cinch the top ring on very tightly, which doesn't allow free and easy movement of the knob. Ended up ordering another one of these kits to rebuild that shower valve with. The aftermarket kit was about half the price of this one, but it's about 1/4 of the quality. Highly recommend this Delta kit!

Perfect fit for a pretty old Delta shower faucet. No more leaks! Very easy installation!

This kit worked. Not an exact match but it seems not no longer leak. The new spring washer parts looked a little smaller, cheaper, but still it works.

I could probably have gotten away with just replacing the washers and springs, but once you have the whole thing torn apart, you might as well replace everything, right? There are some really good videos on YouTube about how to do this. We did have some trouble getting the dome nut off. At first, we used a pipe wrench as recommended in the comments section of the video we watched. Clearly the nut was not coming lose and the entire valve was beginning to twist in the wall. This can lead to catastrophic porblems. We switched to a chanel lock and were able to get it lose and proceed with the repair. My suggestion, soak the entire nut area of your old valve repeatedly for days in advance with some sort of "Bolt Off" lubricant. Before you try to unscrew it, rap on the dome nut all the way around. I don't mean tap lightly nor do I mean for you to beat on it. But you need to knock it pretty good to loosen those threads. Also, get some silicone paste and slather all the new parts up good before you put it back together. Doing this yourself will save you hundreds over what a plumber would charge. Good luck!

Skip the OEM parts and buy the Delta parts. Yes, they cost more, but the Delta parts renewed my 35yr old shower faucet as good as new. Faucet is a much smoother operation and easy to adjust temperature. The same with the diverter valve. I used the OEM parts before but never again.

I replaced authentic Delta parts with these. Did not work well. I removed them and carefully reinstalled them to see if my installation was flawed. Same problem - stiff lever movement, uncertain stop position. Replaced this lit with the authentic Delta kit. Works perfectly. Stick to the Delta parts. They are worth the additional cost.

This fit perfectly to fix a leaking faucet fixture. Improved design from original. Remember to remove the old nylon adjustment ring. It is no longer used. Great design improvement. I had tried an aftermarket replacement that did not work. Only using Delta replacement parts from here on out!

Did just what I needed. Stopped an old leaky Delta faucet from dripping without needing to do any major work or replace the whole thing. Used on a single knob bath/shower diverter faucet and the job was done in 10m.

It works.

Everything you need is in the package, save for the silicon grease (to be applied onto springs, gaskets and ball bearing).

fits well, and works, no more leaking
