4. Installation Guide
The RecPro RV Water Pump Silencer Hose Kit is designed for straightforward installation. Follow these steps to integrate it into your RV's fresh water system:
- Identify Water Pump Connections: Locate your RV's fresh water pump. Identify the inlet (suction) and outlet (pressure) ports of the pump.
- Disconnect Existing Hoses: Carefully disconnect the existing hoses from both the inlet and outlet ports of your water pump. Ensure the water system is depressurized before disconnecting.
- Connect Silencer Hose to Pump: Attach one female end of the 36-inch silencer hose to the outlet port of your water pump. Hand-tighten the connection to prevent leaks.
- Connect Male-to-Male Adapter: If necessary, use the included male-to-male adapter to connect the other female end of the silencer hose to the existing plumbing line that leads into your RV's water system.
- Form the Loop: Position the silencer hose to create a gentle loop. This loop is crucial for allowing water to settle and reduce vibrations before continuing through your plumbing. Avoid sharp bends or kinks in the hose.
- Secure Connections: Ensure all connections are secure and hand-tight. You may use plumbing tape on threaded connections for an extra seal, though the swivel fittings are designed to seal effectively.
- Test for Leaks: Once installed, repressurize your RV's water system and carefully check all new connections for any signs of leaks. Address any leaks immediately by tightening connections or reapplying seals.

5. Operation
Once installed, the silencer hose operates passively within your RV's fresh water system. When the water pump activates, water flows through the silencer hose, which is designed to absorb and dissipate vibrations before they can transmit through the rigid plumbing lines. This results in a noticeable reduction in pump noise during operation. No additional user interaction is required for the silencer to function.
6. Maintenance
The RecPro RV Water Pump Silencer Hose Kit requires minimal maintenance. Regular inspection is recommended to ensure optimal performance and prevent potential issues:
- Visual Inspection: Periodically check the hose and connections for any signs of wear, cracks, kinks, or leaks.
- Connection Tightness: Ensure all fittings remain hand-tight. Over-tightening can damage the plastic components.
- Winterization: During winterization of your RV's plumbing system, ensure that antifreeze is properly circulated through the silencer hose to prevent freezing and potential damage.
- Cleaning: If the hose or fittings become dirty, clean them with mild soap and water. Avoid harsh chemicals that could degrade the materials.
7. Troubleshooting
If you experience issues after installing the silencer hose, consider the following troubleshooting steps:
- Increased Noise: If pump noise increases, check for kinks in the silencer hose that might restrict water flow. Ensure the hose forms a gentle, unobstructed loop. Verify that the pump itself is securely mounted and not vibrating against other surfaces.
- Leaks at Connections: Check all connections for tightness. If leaks persist, disassemble the connection, inspect the rubber washers or O-rings for damage, and reassemble, ensuring proper alignment. Applying plumbing tape to threaded male adapters can also help.
- Reduced Water Flow: Ensure the silencer hose is not kinked or obstructed. Check the water pump's pre-filter for clogs, as this can affect overall water flow.
