How to Fix a Leaky Single Handle Tub/Shower Faucet
Step-by-step Instructions
Leaky tub and shower faucets are not on our list of favorite things. But they’re relatively simple to fix yourself. With a few tools and the right Danco replacement part, you can fix that leaky faucet yourself.
Tools and supplies required: Phillips Screwdriver, Cartridge Puller, Pliers, Needle Nose Pliers, Fine Sandpaper or Steel Wool, Silicone Grease
The easiest way to remove the old Cartridge is to use a Cartridge Puller. Make sure to follow the instructions for the Cartridge Puller, which can be purchased at your local home improvement store. Because Cartridges are unique to specific type of Faucets, you will want to take your old Cartridge 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.
Next, remove the Temperature Limit Stop, Key Stop, Stop Tube, and the Trim Plate (as needed to access Cartridge).
Remove the Retainer Clip carefully as not to drop it behind wall.

Using Silicone Grease, lubricate the inside of the Valve Body about 1”. Then lubricate the Exterior Rubber Components on the Cartridge with Silicone Grease as well.
Insert the new Cartridge, Hot inlet Left Side, Cold inlet Right Side into the Valve Body with the tab stamped “HC” on top and with the Stem Notch down.
Reinstall Trim Plate with original Screws.
Reinstall the Retainer Clip, Stop Tube, Key Stop, and the Temperature Limit Stop, in that order.
Slide the Handle onto the Stem or Handle Adapter onto the Stem. Do not use Handle Screws at this point. Turn the water supply back on and test for leaks and ensure the hot water temperature is adequate. Be sure not to exceed the maximum temperature allowed by local plumbing code. Finally, secure the Handle with the Set Screw and your project is complete.
