RP25513 faucet stem assembly Replacement Kit for two handle faucet repair kit...

I had a leaky Delta bathroom sink, it had a slow leak at the faucet for years. I finally got tired of it and decided to try and fix it. Doing some research, it seemed like the fix would be a cartridge replacement. I took apart the sink handle to try to figure out what model to get, as neither the sink nor hoses had any indicators. Unfortunately, neither did the cartridges. However, comparing pictures, I figured out that this must be the correct model. Replacement cartridges on Delta's site were well over $40. While here on Amazon, knock-off brand cartridges were between $10-20. The reviews for this particular model were promising, so I bought this one. They certainly looked identical, though the color was different (these have white plastic parts compared to the original black), but all that matters is the shape. It wasn't that difficult to swap these out. I did see a leak with the first installation, but I realized that the rubber O-ring had slipped out of place. I took it apart, made sure it was placed correctly, and assembled a second time, and all was well. The negative reviews talking about leaks were probably people making the same mistake I originally had, but if you but this to replace the correct model of cartridge and install it correctly, it will work fine. When all was done, the sink works the same as before. Water flow is the same, handles turn the same. Except now, that slow drip that drove me nuts for years is gone. This is definitely a good model and deserves the solid reviews.

These work great for one fourth the cost. Don’t make the mistake I did. Try these valves from Amazon, before spending four times as much at your local plumbing supply store. I went to a local plumbing supply store to buy replacement cartridges for our bathroom Delta faucets. The plumbing supply store did not have Delta brand. They sold me some third party brand I had never heard of, so I was not really happy with their $70 cost. After I repaired the laboratory faucets, I decided to replace our tub faucets as well, because they were also leaking water beneath the handles when we turn the water on. Instead of going back to the plumbing supply store, I decided to see if Amazon had a lower cost option. These cartridges came with the handle turn stop plastic parts as well as the new springs and new rubber parts at a whole lot cheaper price. I had to buy those things separately at the plumbing supply store. These valves fit our tub faucets perfectly and stopped the leaks. See video. Before I replaced the valves, water would leak beneath the faucet handles. I am buying these valves from Amazon from now on when I need to replace Delta water valves.

Works on my Delta Victorian narrow set lav faucet. Old one leaking through the center oring, which is 8.8 ID x 13 OD but difficult to find. For the price, easier to get new especially with a spring and seat. Leak done, for now. Delta cartridge prices are insane and they don't necessarily last any longer than aftermarket. I have muni water supply, so the water isn't hard either.

Valve dropped right in and stopped my leak I recommend

This item fixed my Delta faucet. I am thankful that I did not have to replace the entire faucet assembly!

Great set and the brass top made it much better than some of the plastic ones

Perfect fit and immediately stopped the dripping from my faucet. Easily installed. Expect them to last a long time and extend the life of the faucet. Good value.

Did not properly fit the faucet body. after installation of both, they both leaked at the base of the cartridge install. A free set of cartridges and seats from Delta directly worked great. Don't trust non-OEM parts for some situations.

Great for repairs.
