Wauebuly Flow Control Spindle Shower Mixing Valves Cartridge Assembly TA-10

Package Include: 1x stem barrel spindle.
If you are replacing the shunt, use a 3/8 lag head screw, carefully insert it until you encounter a little resistance, twist it slightly, push down slightly, and you can easily pull out the old shunt.
Use a hex tool when inserting a shallow hex screw, no cross threads, don't let the screw fall off the hex tool, and just to be on the safe side, buy a spare screw in case it falls off the wall.
