Kohler GP1016515 Valve for Single-Control Faucets

Faucet was leaking around the base. It appeared to have been original to the home so was about 20 years old. Took it apart and found the valve was loose in the housing and was leaking. This valve was a direct replacement and was very easy to install. Works like new and saved me a lot of money and effort over having to replace the faucet.

Great product

Great item!

I needed to fix water leaking around the faucet handle and the replacement cartridge was very easy to install. I decided to also replace the O-rings and bushings while I had the faucet disassembled and recommend replacing those parts, too. If I had to do it again, I'd also replace the spay diverter valve.

This valve kit was exactly what we needed to stop a leak in our 2.5 year old Kohler K-10412 Single Control Faucet (Brushed Nickel finish).The leak started about a week ago and got progressively worse each day, virtually turning into a river two days ago. The parts were delivered yesterday and, with our 14 year old son's help, we fixed the leak this morning. The job took about 20 minutes total (think we could do it in 10 next time though...), and we also replaced the o-rings and slide bearings (Kohler GP30420 O-Ring Seal Kit for Kitchen Faucets with Bearings, O-Rings and Lube) and the friction ring (KOHLER 1005201 Washer Friction) in the process.Here is what we did to replace the valve; if looking for the steps to replace all parts mentioned above, please follow the link to the o-ring kit and read the more expansive worklist:* Turned off the water running to the sink* Put stoppers in the drains on both sides of the sink, just to make sure nothing accidentally went down the drain...* Used a small flat-head screwdriver to remove the plug from the back of the handle, providing access the handle's set screw* Used a small hex (Allen) wrench to loosen the set screw, and then lifted the handle off* Unscrewed (by hand) the covering over the valve (took a bit of 'uumph' to get started, but easy thereafter)* Used a pipe wrench to loosen the mounting nut holding the valve in place, then finished loosening and removing by hand* Removed the old valve; the gaskets from the bottom of the valve were stuck inside the faucet, so we had to clean that out* The valve stem sits in a plastic bracket mounted in the handle; we replaced the old bracket with one that came with the valve* Used soap & the Scotch-Brite material to clean the inside of the handle and faucet* Put the new valve unit in place, lining up the posts on the valve to holes inside the faucet for a perfect fit* Cleaned and replaced the mounting nut; hand tightened, then used the pipe wrench for the final quarter-turn* Cleaned and then screwed on (by hand) the covering over the valve until finger tight* Placed the handle back on top of the valve, lining up the valve stem with the new plastic bracket we installed* Put the set screw back in place, and hand tightened with the hex (Allen) wrench until just snug* Replaced the plug covering access to the set screw* Took the drain stoppers out* Turned the water back on... looked for leaks... turned the faucet on and tested the hot & cold water flow... moved the spout aroundNo leaks. Like new. Excellent.Was a lot nicer to spend $20 instead of $200 for a new unit.If you have the same sort of issue and have confirmed that these parts are right for your unit, we recommend them very highly.Go for it.

Ordered this to repair my kitchen faucet that was leaking pretty bad from under the handle. Replacement was a breeze. The most difficult part of the repair was loosening the protective cover directly under the faucet handle. Once that was off the larger nut that retains this valve came off easily. The replacement took less than 10 minutes including the time I took to clean up the scale that had accumulated due to my hard well water.

This GP1016515 genuine Kohler replacement kitchen faucet valve was a perfect fit to replace the previous valve, the now obsolete Kohler part 106814.If you have a leaky faucet, consider looking elsewhere (not Amazon) for the part.While the genuine Kohler replacement valve Amazon sold me fits and works great, the delivery service was mediocre. The valve was ordered through Amazon Prime on a Wednesday evening. No option for next-day delivery was offered for that specific item. Friday delivery was promised. Subsequently, Amazon/UPS stated delivery would be by 20:00 (8:00 PM) Friday. UPS delivered the item at 19:58 hours (7:58 PM) on Friday. So, Amazon/UPS met the promised delivery time technically. But 8:00 PM Friday delivery is effectively Saturday for all practical purposes. I could have bought the part elsewhere and had it in hand early Friday and fixed the leak the same day instead of having to wait until Saturday.

My kitchen faucet had been fussy for quite a while, leaking out the spigot if I didn't close it carefully. I finally ordered this and put it in just now. Leak is gone now.Before I ordered I watched the installation video from Kohler (easy to find on YouTube) and took a look at my old valve to make sure it matched and confirm that I had the correct tools. I recommend this step for anyone who is unsure of whether or not to order this as a DIY task.I didn't bother ordering the O rings they suggest installing at the same time. I'm not sure, but I think I only would have needed them if the leak had been around the valve instead of through the valve and out the spigot.
