How to Remove an American Standard Shower Diverter Valve
American Standard makes a wide variety of toilet plumbing supplies. Included in many of their shower kits is a diverter valve. The diverter valve controls the flow of water coming from the water supply line. When turned in one direction the water will pour out of the tub spout. Turned in a different direction the water comes out the shower head. After a few years of turning back and forth, your American Standard diverter may begin to wear out, causing leaks.
Turn off the water supply to the shower at the water mains in the basement or by the street.
Remove the cover from the diverter knob with a flat screwdriver.
Remove the screw from the center of the diverter knob. Pull out on the diverter knob.
Turn the bolt coming out of the center of the diverter counterclockwise with a wrench to remove it.
Insert a cartridge puller, available from hardware stores, into the diverter valve. Tighten the handle until the puller is attached to the cartridge. Tug on the cartridge puller with a wrench to remove it from the wall.
Insert the new diverter into the wall. Replace the bolt in the center, as well as the handle. Turn on the water and test.
