Setup and Installation
This section outlines the general steps for replacing your faucet valve cartridge. Specific faucet models may have slight variations.
- Prepare the Work Area: Clear the area around the faucet. Place a towel or cloth in the sink/tub to catch any drips or dropped parts.
- Shut Off Water Supply: Locate the hot and cold water shut-off valves under the sink or at the main water supply. Turn them off completely. Open the faucet to drain any remaining water from the lines.
- Remove Faucet Handle: Depending on your faucet model, remove the decorative cap (if present) and unscrew the handle. This usually involves a set screw located on the side or back of the handle.
- Remove Trim Plate and Sleeve: Carefully remove any trim plates, escutcheons, or sleeves that cover the cartridge area.
- Remove Old Cartridge: The cartridge is typically held in place by a retaining nut, clip, or screws. Use appropriate tools (e.g., pliers, screwdriver) to remove the retaining mechanism. Gently pull or pry out the old cartridge. Note its orientation for correct installation of the new one.
- Clean Cartridge Housing: Inspect the cartridge housing for any debris, mineral deposits, or old O-rings. Clean the area thoroughly to ensure a proper seal with the new cartridge.
- Install New Cartridge: Apply a thin layer of plumber's grease to the O-rings of the new American Standard 051337-0070A cartridge. Insert the new cartridge into the housing, ensuring it is correctly oriented. The cartridge may have alignment tabs or notches that need to match the housing.
- Secure New Cartridge: Reinstall the retaining nut, clip, or screws to secure the new cartridge firmly in place. Do not overtighten.
- Reassemble Faucet: Reinstall the trim plate, sleeve, and faucet handle in reverse order of removal.
- Restore Water Supply: Slowly turn on the hot and cold water supply valves. Check for leaks around the faucet base and connections.
- Test Faucet: Operate the faucet handle to check for proper water flow and temperature mixing.

Maintenance
The Ultramix Faucet Valve Cartridge is designed for durability. Regular maintenance is generally not required for the cartridge itself. However, to ensure optimal performance and longevity of your faucet system:
- Inspect for Leaks: Periodically check around the faucet base and under the sink for any signs of leaks. Address any leaks promptly to prevent water damage.
- Clean Faucet Aerator: If water flow becomes restricted, the faucet aerator may be clogged with mineral deposits. Remove and clean the aerator as needed.
- Avoid Harsh Cleaners: When cleaning the faucet exterior, use mild soap and water. Avoid abrasive cleaners or chemicals that could damage the finish or internal components.
