Installation and Support
Before disassembling your faucet, turn your water off at the supplies under the sink. With the supplies off, move the handle to the “on” position and drain the system of water.
To rinse the interior of the valve first place a bowl or similarly shaped device over the faucet. This will be necessary to redirect the water back into your sink, shower or bath tub.
After placing the bowl over you faucet, slowly turn on your supply lines back on to flush clean water through your open valve body. This will push the debris and residue up and out of the valve body.
Remove water from the inside of the valve using a rolled up paper towel and reinstall the cartridge .
