Installation & Reassembly Of The Cartridge
Using a soft nylon brush, clean the inside of the brass valve body to insure there is not any debris or buildup on the walls of the chamber. Be sure the chamber is clean and dry before inserting the new cartridge.
Look into the brass chamber to find a notch in the brass. Then, find the white, plastic tab on the side of the cartridge. Insert the cartridge so the tab is fully seated in the notch in the brass.
Next, reassemble your faucet by working backwards from steps 3 to 1.
You are all done!
