3. Installation Instructions
Safety First: Before beginning installation, ensure your water heater is turned off, cooled, and depressurized. Refer to your water heater's manual for specific safety procedures.
- Prepare Water Heater: Turn off the power or gas supply to the water heater. Allow the water to cool. Close the cold water inlet valve to the water heater and open a hot water faucet in your RV or home to relieve pressure.
- Remove Existing Drain Plug/Valve: Place a bucket or pan under the water heater drain port. Carefully remove the existing drain plug or valve. Be prepared for residual water to drain.
- Apply Thread Sealant: Apply a suitable thread sealant (e.g., PTFE tape or pipe thread compound) to the 3/4" NPT inlet threads of the Camco 11523 drain valve. This helps ensure a watertight seal.
- Install New Valve: Thread the Camco 11523 drain valve into the water heater's drain port. Hand-tighten first, then use a wrench to tighten securely. Do not overtighten, as this is a plastic component and excessive force can cause damage.
- Check for Leaks: Once the valve is installed, close the hot water faucet, open the cold water inlet valve to the water heater, and allow the tank to refill. Inspect the newly installed valve for any leaks. If leaks are present, tighten slightly or reapply thread sealant.

4. Operation
The Camco 11523 drain valve is designed for straightforward operation to drain your water heater.
- To Open the Valve: Rotate the gray easy-grip handle counter-clockwise until the valve is fully open. Water will begin to drain from the 3/4" NH thread outlet. You may attach a standard garden hose to direct the water away from your RV or home.
- To Close the Valve: Rotate the gray easy-grip handle clockwise until the valve is fully closed. Ensure it is snug to prevent leaks, but avoid excessive force.

5. Maintenance Guidelines
Regular maintenance helps ensure the reliable performance and extends the lifespan of your drain valve.
- Inspect for Leaks: Periodically check the valve and its connection to the water heater for any signs of leaks. Address any leaks promptly by tightening or reapplying thread sealant.
- Clean as Needed: If mineral deposits or debris accumulate around the valve, clean it gently with a soft brush and mild soap. Avoid harsh chemicals that could damage the plastic.
- Winterization: During winterization of your RV or water system, ensure the valve is fully open to allow complete drainage of the water heater, preventing freeze damage.
6. Troubleshooting Common Issues
| Problem | Possible Cause | Solution |
|---|---|---|
| Valve leaks after installation. | Improper thread sealant application, insufficient tightening, or overtightening causing thread damage. | Ensure adequate thread sealant is applied. Tighten the valve securely but avoid excessive force. If threads are damaged, replacement may be necessary. |
| Water heater does not drain completely. | Valve not fully open, or internal blockage in the water heater or valve. | Ensure the handle is rotated fully to the open position. Inspect the valve and water heater drain port for any debris or sediment. |
| Valve does not fit water heater. | Incorrect thread size or shank length for the specific water heater model. | Verify the water heater's drain port specifications. This valve features a 3/4" NPT inlet and 2-1/2" shank. Some water heaters (e.g., certain Atwood models) may require a 1/2" NPT valve. |
