Plumbing Valves

If you don't have shut off valves for the shower, you have to turn off the water supply throughout the house plan accordingly and tell family members that life as they know if will cease to exist. Use heavy cardboard or old drop cloths to protect the surface of the tub while you work on the faucet. Assuming that you can get to the valve through a service panel, removing the old valve is rather straightforward. Of course you can cut into the bathroom wall if you're really determined to get this sucker out. Here's what you do:

1. Turn the water off. Few of the older tub or shower valves were not installed with shut-off valves so you will have to turn off the water at the main valve. Open the valve to allow the water to drain.
2. Remove the handles and escutcheons From the bathtub side of the wall, remove the handles. Most handles are held in place by a screw in the center of the knob. The screw may be under a cover. Remove the screws and then pull off the hot and cold handles. If there is a diverter handle for the valve, which sends water from the tub to the shower, remove it.
3. Remove the spout. Place the handle of a large screwdriver into the opening in the end of the spout and use it as a lever to turn the spout in a counterclockwise direction. After a turn or so you should be able to unscrew the spout by hand.
4. Remove the showerhead. Use slip-joint pliers to loosen the showerhead. Because you're replacing it, don't worry about damaging the finish. Also, unscrew the showerhead and pipe coming out of the wall that the showerhead was attached to.
5. Loosen the union joints. Move to the other side of the wall, and use two pipe wrenches to loosen the unions connecting the valve to the hot and cold water supply pipes. If you don't have unions, you have to cut the pipes with a hacksaw.
6. If you have copper or plastic pipes or you don't have any pipe unions in galvanized pipe, use a hacksaw to cut these pipes a foot or so below the valve. Cut the hot and cold pipes carefully so you get a nice, square end. A little bit of extra time spent cutting carefully make the pipes easier to solder or to have a new section glued on. (You don't have to be too careful cutting the galvanized pipe because you have to replace that section of pipe.)
7. Remove the valve body and any mounting hardware. The valve body may be screwed to the wall framing or held in place by pipe straps. Remove the hardware and body.
8. Save the pipe that leads up to the showerhead. The top of this pipe may be held in place by a fitting called a drop ear elbow. You can reuse this pipe.
