Without a diverter valve, every bathtub-shower combination would have one set of controls for the water that exits from the bathtub spout and another set that regulates the water that comes out of the showerhead. A diverter valve is simply a switch that changes, or "diverts," the incoming water to either the bathtub spout or to the showerhead. Unfortunately, diverter valves develop problems, and leaks are the result. Thankfully, replacing a shower diverter manufactured by Delta is simple.
Things You'll Need
- Deep-socket or a stem-socket kit
Turn the main water supply off by twisting the water supply valve next to the water meter in a clockwise direction with a wrench.
Place a towel over the tub's drain to prevent the risk of lost parts.
Pry the cap off of the middle of the diverter valve with a screwdriver, then use the screwdriver to remove the screw from the center of the handle. Pull the handle away from the wall of the shower to remove it.
Remove the screws holding the trim plate that surrounds the valve and rests against the shower's wall with a screwdriver, then pull the plate away from the wall.
Insert a deep-socket or a stem-socket kit into the shower's wall and twist the socket until it locks onto the edges of the diverter valve. Twist the valve with the socket in a counterclockwise direction until the valve can be withdrawn from the wall.
Insert the replacement diverter valve into the shower's wall, then tighten the valve in place with either the deep-socket or the stem-socket kit. Place the trim plate over the valve and against the wall, then install the plate's screws with a screwdriver.
Slide the valve's handle onto the tip of the diverter valve and install the handle's single screw with a screwdriver. Press the handle's cap into place in the center of the handle.
Turn the main water supply back on to complete the replacement process.
