To clean a mixing valve, you'll need to remove it first and then soak it in a cleaning solution. Here's a step-by-step guide:
- Remove the Mixing Valve Body: Disconnect the piping that connects to the mixing valve body, allowing you to remove the valve itself ([0:13]).
- Prepare a Cleaning Solution: Once the mixing valve body is removed, you can prepare a cleaning solution ([0:13]).
- Soak the Valve: Soak the mixing valve body in either a vinegar-water solution or a CLR (Calcium, Lime, Rust) or Lime-Away solution for a few hours ([2:05]).
- Rinse and Reassemble: After soaking, rinse the valve thoroughly and reassemble it.
Here’s a more detailed breakdown:
Cleaning a Mixing Valve: A Step-by-Step Guide
| Step | Description |
|---|---|
| 1. Removal | Carefully disconnect the pipes attached to the mixing valve. Pay attention to how they're connected to make reassembly easier. |
| 2. Inspection | Examine the valve for any visible signs of mineral buildup or corrosion. This will help you determine the soaking time needed. |
| 3. Soaking | Immerse the valve body in your chosen cleaning solution (vinegar-water or CLR/Lime-Away). Ensure the entire valve is submerged. A ratio of 1:1 for vinegar and water usually works well. |
| 4. Waiting | Let the valve soak for several hours. The exact time depends on the level of buildup. Check periodically to see if the deposits are loosening. ([2:05]) |
| 5. Scrubbing | After soaking, use a small brush (like an old toothbrush) to scrub away any remaining mineral deposits. Pay attention to small crevices and openings. |
| 6. Rinsing | Thoroughly rinse the valve with clean water to remove all traces of the cleaning solution. |
| 7. Reassembly | Carefully reassemble the mixing valve, ensuring all connections are tight and secure. Use plumbers tape on threaded connections to prevent leaks. |
| 8. Testing | Turn on the water supply and test the valve to ensure it's functioning correctly and there are no leaks. Adjust the temperature settings to verify proper mixing. |
Recommended Cleaning Solutions
-
Vinegar-Water Solution: A natural and mild option, suitable for light mineral buildup. It's generally safe for most valve materials.
-
CLR/Lime-Away: A stronger chemical solution designed to dissolve calcium, lime, and rust deposits. Use with caution and follow the manufacturer's instructions.
- Note: Always wear gloves and eye protection when handling CLR or Lime-Away.
- Caution: Ensure adequate ventilation when using these chemicals.
Tips for Maintaining Your Mixing Valve
- Regular Inspections: Periodically check your mixing valve for any signs of leaks or reduced performance.
- Water Softener: If you have hard water, consider installing a water softener to reduce mineral buildup in your plumbing system.
- Professional Maintenance: Consider having a plumber inspect and maintain your mixing valve annually, especially in areas with hard water.
