Always be sure to turn off the water in the home before disassembling the faucet.
Single knob shower faucets involve fewer parts, making for a quicker disassembly than shower faucets that have two or even three control handles. You will need to take the faucet apart if you have decided to install a new one, or if the shower is dripping water. If you have any questions about replacement parts, take the old faucet parts with you to the plumbing supply or home improvement store to get an exact match.
Instructions
1. Turn off the water in the house before you begin by closing the main water valve. Turn on a faucet, if possible on a lower level of the house, and leave it one while you take the faucet apart.
2. Place a towel over the shower's drain so you do not lose any parts. Remove the retaining screw on the faucet handles, which are either located in a small recess in the base of the handle or under a plastic cap in the middle of the handle.
3. Pull off the handle from the faucet, or clamp a handle puller on each handle that does not come free easily and twist the center post until the handle comes free. Unscrew any plastic adapter pieces located below the handle, slide off the metal washer from the stem and lift the clip out of the faucet using a small flat-head screwdriver.
4. Clamp a pair of pliers onto the faucet's valve cartridge and twist it counterclockwise to remove it from the faucet. If the valve cartridge is stuck, slide a cartridge puller onto the cartridge and line up the notches on the tool with the notches in the cartridge, then twist the handle on the puller counterclockwise.
5. Reassemble the faucet in the reverse order you took it apart, making sure to twist the different parts clockwise until they sit firmly in place.
