Installation (Setup)
Follow these steps to replace your faucet cartridge. A specialized cartridge removal tool may be required for easier installation, depending on your faucet model.
- Turn off Water Supply: Locate the shut-off valves for your faucet (usually under the sink) and turn them off completely. If no individual valves are present, turn off the main water supply to your home.
- Drain Faucet: Open the faucet handles to drain any remaining water from the lines.
- Remove Faucet Handle(s): Carefully remove the decorative cap (if present) on the faucet handle. Unscrew the handle screw and lift off the handle. Repeat for the second handle if applicable.
- Remove Trim and Escutcheon: Remove any trim pieces or the escutcheon plate that might be covering the cartridge.
- Remove Retaining Nut/Clip: Identify the retaining nut or clip that holds the old cartridge in place. Use an adjustable wrench or appropriate tool to loosen and remove the nut, or carefully remove the clip.
- Extract Old Cartridge: Gently pull the old cartridge straight up and out of the faucet body. If it is stuck, a cartridge puller tool (often sold separately) may be necessary.
- Clean Faucet Body: Inspect the faucet body for any debris or mineral buildup. Clean the area thoroughly before installing the new cartridge.
- Install New Cartridge: Insert the new Moen 1258 Duralast cartridge into the faucet body, ensuring it is properly aligned. The cartridge typically has alignment tabs or notches that must match the faucet body.
- Secure New Cartridge: Reinstall the retaining nut or clip, tightening it securely but without overtightening.
- Reassemble Faucet: Reattach the escutcheon, trim pieces, and faucet handle(s) in reverse order of removal.
- Restore Water Supply: Slowly turn the water supply valves back on.
- Check for Leaks: Turn on the faucet and check for any leaks around the base of the handles or connections. Operate both hot and cold water to ensure proper function.

Operating Instructions
The Moen 1258 Duralast cartridge provides smooth and precise control over water flow and temperature in your two-handle faucet. Once installed, operate your faucet as usual:
- Water Flow: Turn the handle(s) to increase or decrease the water flow.
- Temperature Control: Adjust the hot and cold handles independently to achieve your desired water temperature.
The Duralast design ensures a consistently smooth handle feel and reliable performance.
Maintenance
Proper maintenance helps extend the life of your faucet and cartridge:
- Regular Cleaning: Clean the exterior of your faucet regularly with a mild soap and water solution. Avoid abrasive cleaners or harsh chemicals, as these can damage the finish.
- Check for Leaks: Periodically inspect the faucet and connections for any signs of leaks. Address any leaks promptly to prevent water damage.
- Mineral Buildup: In areas with hard water, mineral buildup can affect faucet performance. If you notice reduced flow or stiff handles, consider disassembling the faucet and cleaning any mineral deposits from the cartridge area.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Faucet leaks from handle base | Improperly seated cartridge, worn O-rings, loose retaining nut. | Ensure cartridge is fully seated and retaining nut is tightened. Inspect O-rings for damage. |
| Reduced water flow | Mineral buildup in cartridge or aerator, partially closed shut-off valve. | Clean aerator. Check shut-off valves are fully open. Consider cleaning cartridge area. |
| Stiff or difficult to turn handle | Mineral buildup, lack of lubrication. | Disassemble and clean the cartridge area. Apply plumber's grease to O-rings if necessary. |
| Water temperature not adjusting properly | Cartridge misalignment or internal damage. | Verify cartridge alignment. If problem persists, the cartridge may need replacement. |
