  1. john shimkus

    your video is very poor it shows nothing about installing replacement part 7s-10d to say the least
    it is useless

    No instructions and the videos did not relate to this part at all. Very disappointed.

    I jus bought a shower diverter and installed it. Shower and tub spout still both leak and there’s no instruction videos. The one I saw suggested was the incorrect one as I’m dealing with hot and cold stems and a diverter stem in the middle. Please help.

    The new part seems so much tighter than the old part. But that’s to be expected as the old part was so worn it wouldn’t work any longer. The replacement went in and works perfectly.

  5. Jessica

    This thing is a bunch of bull. There’s no instructions anywhere on installing it in a shower, it won’t sit flush and when you call no one knows how to answer. If your going to sell a product, include instructions or have employees who can answer a phone call.

  6. Daniel Brock

    Fixed your instructions for the 7s-10d diverter stem. What a waste of time. Your product sucks.

  7. Adis

    Nothing related to 7s-10D. I replace it and peak still was there. Waist of money!

  8. Lee Hanna

    Worst part ever. Tried three of them until I finally had to use Emery paper to get it to fit without binding. It finally worked with cold water, but leaked. When hot water was turned on, the plastic deformed and the whole thing jammed up and broke..
    Still no instruction...Read More

    I am on my fourth replacement valve. The softer plastic piece binds up within a month of install. Lack of instructions would make one feel that it is being installed incorrectly, but everything fits flush and does not leak.

  10. Glen Smith

    Product fits so tight that it broke immediately when trying to turn it. I bought another one and it fit the same- TOO TIGHT. So, I sanded down the pad that “closes/diverts” the water and also sanded the opposite side until it fit snug but was able to turn with RE...Read More

    7S-10D DIVERTER STEM: I have replaced this diverter stem twice – last a few weeks – same problem as before – water comes out of the shower head and faucet when water is turned on. How are the diverter stem’s holes supposed to be lined up with the holes in the valve ins...Read More

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.
