Setup and Installation
This section outlines the general steps for replacing an existing valve with the Delta Faucet RP60400. Specific faucet models may have minor variations.
- Prepare for Installation: Locate the water shut-off valves underneath your sink and turn them off completely. Test the faucet to ensure water flow has stopped.
- Access the Valve: Depending on your faucet model, you may need to remove the handle(s) and any decorative escutcheons to expose the valve assembly. Refer to your faucet's specific instructions for this step.
- Remove Old Valve: Carefully remove the old valve from its housing. This may require a wrench or pliers. Note the orientation of the old valve as you remove it, especially any arrows or alignment tabs.
- Install New Valve: Insert the new Delta Faucet RP60400 Valve into the faucet body. Ensure that the arrow on the lower (black) body of the valve points towards the inside of the faucet. The tabs on the valve body should align with the notches in the brass body underneath.
- Secure the Valve: Snugly tighten the retaining nut that holds the valve in place. Do not overtighten.
- Reassemble Faucet: Reattach any handles and decorative components that were removed.
- Restore Water Supply: Slowly turn the water shut-off valves back on. Check for any leaks around the newly installed valve and faucet connections.
- Test Faucet: Operate the faucet handles to ensure proper hot and cold water flow and temperature control.
Operating Instructions
The RP60400 valve is an internal component that controls water flow and temperature within your two-handle Delta faucet. Once installed, its operation is integrated with the faucet handles. Turning the handles will rotate the valve internally to allow water to pass through and mix to your desired temperature.
Maintenance
Proper maintenance of your faucet and its components can extend their lifespan and ensure optimal performance.
- Regular Cleaning: Clean the exterior of your faucet regularly with a mild soap and water solution. Avoid abrasive cleaners or harsh chemicals that can damage the finish.
- Leak Detection: Periodically check for any drips or leaks from the faucet spout or around the handles. Early detection can prevent further damage.
- Component Inspection: If a leak develops, the issue may not always be the valve itself. Other components such as gaskets and springs (e.g., Delta RP4993) may also require inspection and replacement. Consult your faucet's specific parts diagram or contact Delta support for guidance on identifying the correct replacement parts.
Troubleshooting
This section addresses common issues you might encounter with your faucet after valve replacement.
- Faucet Still Leaks or Drips:
- Ensure the valve is fully seated and the retaining nut is snug.
- Verify that the correct RP60400 valve was installed for your specific Delta faucet model. Delta frequently updates internal parts while maintaining exterior designs, making correct part identification crucial.
- Inspect other internal components like springs and gaskets for wear or damage.
- No Water Flow or Reduced Flow:
- Check that the main water supply valves are fully open.
- Ensure the valve is correctly oriented and seated.
- Incorrect Hot/Cold Water Mix:
- Verify that the hot and cold water lines are connected correctly to the faucet.
- Confirm the valve is installed with the correct orientation (arrow pointing inward).
If troubleshooting steps do not resolve the issue, it is recommended to contact Delta Faucet customer service for further assistance.
