How to Remove Air from a Water Motor?
Removing air from a water motor, often referred to as an airlock, is crucial for its proper function. The process varies slightly depending on the specific motor's design but generally involves these steps:
Before attempting any solution, ensure you have correctly identified the problem as an airlock. Symptoms include reduced water flow, unusual noises, or the motor failing to operate efficiently.
Methods to Remove Air
Several methods effectively remove trapped air from a water motor:
1. Run the Motor with Discharge Hose Disconnected
This is a straightforward approach.
- Steps: Disconnect the discharge hose from the water motor. Run the motor until a steady stream of water flows from the discharge port, indicating that most of the air has been expelled. Reconnect the hose, ensuring a tight seal on all connections.
2. Utilize Bleeder Valves (If Equipped)
Many water motors have a bleeder valve specifically designed for air removal.
- Steps: Locate the air bleed valve (often a small screw or valve). Open the valve and allow trapped air to escape. Continue until a steady stream of water flows out, then close the valve tightly.
3. Slow Filling of the System
For some systems, gradually introducing water can help.
- Steps: Slowly open the fill valve, allowing water to enter the system gradually. This allows trapped air to escape more easily than with a rapid fill.
4. Check for Leaks and Ensure Tight Connections
Air entering the system through leaks can hinder operation.
- Steps: Carefully inspect all connections and seals for any leaks. Tighten any loose connections to ensure a secure, airtight system.
5. Increase Pressure Head (If Applicable)
In some cases, increasing the water pressure entering the motor can aid in air removal.
- Steps: This may involve adjusting the inlet valve or the source water pressure. Consult your water motor's manual for the appropriate adjustments.
Troubleshooting Additional Issues
If the above steps don't resolve the airlock, additional troubleshooting might be necessary. Consider:
- Inspecting the pump impeller: A damaged impeller can contribute to air ingestion.
- Checking for blockages: Debris or other obstructions in the system might impede water flow.
- Consulting the owner's manual: Your water motor's manual contains valuable specific instructions.
Remember safety precautions when working with water motors and plumbing systems. If you are unsure about any steps, consult a qualified professional.
