Is your shower faucet not working correctly? Fix it with a new faucet cartridge!
Troubles with your tub and shower faucet can be surpisingly easy to fix. For a faucet that struggles with turning on and off, it's likely that the shower faucet cartridge needs to be replaced.
Once you shut off the water and remove the handle and escutcheon, you can quickly determine whether your single-handle tub and shower faucet is a cartridge, ball, or disk type.
Tub cartridge faucets work just like sink cartridge faucets. Usually the faucet only turns water on and off; a diverter valve on the spout directs water to the showerhead or the spout. A number of manufacturers make cartridges of varying designs, so take the cartridge with you when you shop for parts. You may need to replace the entire cartridge. Follow our steps below to see how to check your cartridge and get the job done.
