2. Safety Information
Always prioritize safety when performing plumbing repairs. Follow these guidelines:
- Turn off the water supply: Before starting any work, locate and turn off the main water supply valve to your house or the shut-off valves for the specific faucet being repaired.
- Wear appropriate personal protective equipment: Eye protection (safety glasses) is recommended to prevent injury from debris or splashes.
- Use correct tools: Ensure you have the necessary tools for the job, such as adjustable wrenches, screwdrivers, and pliers.
- Handle parts carefully: Small parts can be easily lost. Work in a well-lit area and consider placing a cloth over the drain opening to prevent parts from falling into the drain.
- Do not overtighten: When reassembling, tighten nuts and connections firmly but avoid overtightening, which can damage components.
3. Kit Components
The Danco STEM Repair Kit 124102 typically includes the following components necessary for repairing an American Standard faucet stem:
- Replacement Faucet Stem: A brass component that controls water flow.
- Washers: Various rubber washers designed for sealing points within the faucet.
- O-Rings: Rubber rings used to create watertight seals around moving parts.
- Seat Washer: A specific washer located at the bottom of the stem, crucial for preventing drips from the spout.

4. Installation Instructions
Follow these steps to replace the faucet stem using the Danco STEM Repair Kit 124102:
- Turn Off Water Supply: Locate the hot and cold water shut-off valves under the sink and turn them clockwise until fully closed. If no individual valves are present, turn off the main water supply to your home.
- Drain Faucet: Open the faucet handles to release any remaining water pressure and drain the lines.
- Remove Faucet Handle: Depending on your faucet model, you may need to pry off a decorative cap (often marked H or C) to expose a screw. Use a screwdriver to remove this screw and lift off the handle.
- Remove Packing Nut/Bonnet Nut: Using an adjustable wrench, carefully loosen and remove the large hexagonal nut (bonnet nut or packing nut) that holds the stem in place. Turn counter-clockwise.
- Extract Old Stem: Once the bonnet nut is removed, you can typically pull the old stem straight out of the faucet body. Inspect the old stem for worn washers or damage.
- Clean Faucet Body: Use a cloth to clean any debris or mineral deposits from inside the faucet body where the stem sits. This ensures a proper seal for the new components.
- Install New Stem Components: Replace any worn washers or O-rings on the new Danco stem with the ones provided in the kit, matching their positions to the old stem. Ensure the seat washer at the bottom of the stem is correctly installed.
- Insert New Stem: Carefully insert the new Danco stem into the faucet body, aligning any splines or notches.
- Reinstall Bonnet Nut: Thread the bonnet nut back onto the faucet body and tighten it with an adjustable wrench. Do not overtighten; it should be snug.
- Reattach Handle: Place the faucet handle back onto the stem, secure it with the screw, and replace any decorative caps.
- Restore Water Supply: Slowly turn the hot and cold water shut-off valves back on.
- Test for Leaks: Turn on the faucet and check for any leaks around the handle base or from the spout. If leaks occur, gently tighten the bonnet nut or re-check the installation of washers and O-rings.
5. Operation
Once the Danco STEM Repair Kit 124102 is correctly installed, your American Standard faucet should operate smoothly. Rotate the faucet handle to control the flow and temperature of water. The stem's internal mechanism, along with the washers and O-rings, ensures a watertight seal when the faucet is closed and allows for precise water regulation when open. Avoid using excessive force when turning the handle, as this can prematurely wear out components.
6. Maintenance
Regular maintenance helps prolong the life of your faucet and prevents future issues. Consider the following:
- Periodic Leak Checks: Periodically inspect your faucet for any signs of dripping from the spout or leakage around the handle base. Addressing minor leaks promptly can prevent larger problems.
- Washer and O-Ring Replacement: If you notice the faucet handle becoming stiff to turn, or if new leaks develop, the rubber washers and O-rings may be worn. These components are designed to wear over time and can be replaced using another Danco repair kit.
- Aerator Cleaning: The faucet aerator (at the tip of the spout) can accumulate mineral deposits, affecting water flow. Unscrew and clean it periodically.
7. Troubleshooting
Refer to the table below for common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Faucet drips from the spout | Worn seat washer or improper installation of the stem. | Ensure the seat washer is correctly seated at the bottom of the stem. Replace the seat washer if worn. Confirm the stem is fully closed. |
| Leakage around the handle base | Loose bonnet nut or worn O-rings/packing washers. | Gently tighten the bonnet nut. If the leak persists, replace the O-rings or packing washers on the stem. |
| Stiff or difficult to turn handle | Lack of lubrication or worn O-rings. | Disassemble the stem and apply plumber's grease to the O-rings. Replace O-rings if they appear cracked or flattened. |
| No water flow or reduced flow | Water supply turned off, clogged aerator, or debris in the line. | Check water supply valves. Clean the faucet aerator. If issues persist, consult a professional plumber. |
