Uninstalling the 1225 cartridge
1. Caution: Always turn your water supplies off before disassembling your faucet. With the supplies turned off, move your faucet’s handle to the “on” position to relieve pressure.
- If there is a double-D washer, slide this off of the top of the cartridge stem.
- Locate the U-shaped copper clip on the top of the faucet. Slide this out to remove.
- Using the twisting tool provided in the 1225 cartridge kit, rotate the cartridge 1/4 of a turn in either direction.
- Grab the cartridge stem with pliers and pull the cartridge out. This might move easy at first, and then require more effort. Keep pulling until it pops out.
Caution: This may pop out suddently. Be sure not to have anyting above cartridge.
- Clean the inside of the valve body with a soft bristled nylon brush (e.g. old toothbrush), to remove any mineral buildup. After cleaning, place a bowl upside down on the open valve to redirect any water splash into the sink. Then, turn on the water supply lines slighly to flush clean water through the open valve.
**Important** After removing cartridge, we recommend cleaning the inside of the valve body (shown below) with a soft bristled nylon brush (e.g. old toothbrush), to remove any calcium build up. After cleaning, turn on water supply lines slightly to flush clean water through the open valve. We recommend placing a bowl or cup over top of valve (for lavatory and kitchen faucets) or under the valve body (for shower faucets)-to redirect any water splash into the sink or tub/stall.
