Every manufacturer of shower faucets has its own idiosyncratic approach to design, but on the whole, shower faucets fall into one of three categories: cartridge, ball valve and compression. If your faucet has a single handle, you'll find either a cartridge or ball valve when you disassemble it. A pull-out shower faucet has a cartridge valve. If the faucet has two handles, it has compression valves or two separate cartridges. The shower diverter, if it's built into the wall, usually has a valve somewhere between a cartridge valve and a compression valve.

No matter which type of faucet valve you have, the process for disassembling it is essentially the same. The job can be more or less complicated, however, depending on the features the manufacturer built into it. Moen, the king of cartridge faucets, offers models with temperature limiters and pressure-regulating mechanisms. 

A general disassembly procedure works for most faucets, but if you're in doubt about the details of your shower faucet, look up the manual on the manufacturer's website. It will alert you to any features that you need to take into account when taking the faucet apart.

Disassembling a Pull-Out Shower Faucet

If you have to pull out the handle of your shower faucet to turn on the water, the faucet has a cartridge. If the faucet leaks or you can't control the temperature, you usually have to remove the cartridge and clean it or replace O-rings and gaskets. The procedure begins with turning off the water to the shower and opening the faucet to release water pressure.

Lever-style handles are held on by an 1/8-inch hex screw located under the lever. Remove it with a hex wrench.

The next step is to pull the cartridge out of the housing,.Momali faucet, you usually have to unscrew and remove an outer metal sleeve to expose a large retaining ring that you can unscrew with locking pliers. Once the pin or nut has been removed, you should be able to pull the cartridge out.

Taking Apart a Ball-Valve Faucet

After removing the handle from a ball-valve faucet, the next thing to do is to unscrew the dome-shaped bonnet. You usually need to grip it with pliers to do this.

Inside, you'll find rubber gaskets around the hot and cold inlets, and there are springs underneath them. Lift out the gaskets and springs with a screwdriver and replace them.

Two-Handle Faucet Repair

When a two-handle faucet leaks, you must extract the valve stem from the valve housing to fix it. First, remove the handle. If it's broken, a shower handle replacement may be in order. Next, unscrew the valve using a pair of locking pliers and pull it out of the valve housing.

Sometimes, the faucet is leaking because one of the valve seats is cracked. The valve seats are replaceable, and to remove one, you need a seat wrench, which looks a bit like a hex wrench. Insert the wrench into the valve housing and through the valve seat, and then turn the seat counterclockwise to unscrew it.
