  1. David

    The Danco replacement. Atem worked wonderfully because you t comes with a replacement value e seat and spring unlike the Delta brand replacement. To he how to video and instructions suck however. Turned out to be easy slide in replacement though.

  2. Justin Time

    Part seems fine, but the instructions on this site are utterly worthless. It may be more accurate to say nonexistent. It would cost nothing to print an exploded view of the part as it is to be installed on the inside of the wraparound inner sleeve/label.

  3. Vincent Lehotsky

    The Spring and the Cap installation has been omitted from this video.
    While the instructions are great, one is left with extra parts that came with the purchase.

      Thank you for your feedback. We have passed along your concern to our Product Management and Creative Services team for further review on our installation video.

    Product is fine, works great. Installation video sucks. Does not mention or show string and seat placement.

  5. scott

    The instructions does not show you how to install the 3s-10h/c it says you do the reverse of how you took it apart. That does not help

    Product seems fine for my Delta faucet but what di do with the spring and plastic bushing? Install instructions? Non existent. I have parts left over!

  7. Monty May

    The stem worked perfectly after installation. Regarding the spring and the rubber thing, a Google search revealed a video that made it clear that the rubber cap and the spring is to be inserted in the recessed hole at the bottom and the stem is to be placed on top of it. ...Read More

    As noted by others, video and instructions are worthless. The phone support is worthless, too

  9. Glenn Peabody

    It works, but I have to agree with others who mentioned the woefully inadequate “how to” video. Placing the seat is the most important step in the process since that seal is most likely to be compromised. A simple diagram of what goes where and proper orientation w...Read More

    Video is useless. It was for a completely different product. I wish I could say that it was missing some information. But it was instructions to totally a different product.

  11. Chad Haines

    Detailed instructions on the site? What a joke

Step-by-step instructions

Is anything more annoying than a leaky faucet? Maybe not; But it's also well within your power to fix it yourself with Danco. Read on, to find out how. Tools and supplies required: Flat head screwdriver, Phillips head screwdriver, wrench, seat removal tool (optional)

First, determine the source of the leak. If water is leaking from underneath the handle onto the counter, the stem of whichever handle is leaking needs to be replaced. If water is dripping from the faucet, turn off the hot water supply valve under the sink. If water is still dripping, you need to replace the cold stem (right handle). If the water stops dripping when you turned off the hot water valve, you need to replace the hot stem (left handle). Once you’ve determined the trouble stem, turn off the water supply.


Remove the Handle by lifting off the Index Cap with a flathead screwdriver. Next, Remove the handle (so the stem is visible) by loosening the Set Screw by the screw counter-clockwise. Set aside the Handle, Set Screw and Handle Button to reinstall at the end of the project.  


If you have a plastic stem, unscrew the top cap and pop out the stem. If you have a brass stem, remove the stem by using a wrench and rotating it counter clockwise until it threads out entirely. Take a look at the Washer which is located on the lower end of the Stem. If the Washer is squeezed flat or has a groove worn in it, a Washer Kit coupled with a new Faucet Seat will likely solve your problem. When replacing the faucet seat, you can remove and replace the seat with an Allen wrench or a seat removal tool. Turn the seat counterclockwise to loosen, clockwise to tighten. Once removed, you will need to take your stem to your local home improvement store and use the Perfect Match locator system from Danco or use the online Stem Finder. This system makes it easy to find your replacement.


Once you have purchased your new stem, you can install it into your faucet

  • Install a brass stem by rotating clockwise until it threads entirely and tighten with a wrench.
  • Install a plastic stem by placing the stem into the handle base and screw on the top cap.


Now is a great time to upgrade your faucet’s appearance with universal metal handles. How to install the new universal handles

  • Place the handle adapter over the stem and tighten
  • Place the new handle on the adapter and insert the handle screw into the washer then into the handle and tighten.
  • If your new handle has an index button, place it on the handle.
Finally, turn the water back on to ensure the leak is fixed.
