Jet Pump Air Lock
An airlock in a jet pump refers to the situation where air becomes trapped in the pump or suction line, disrupting water flow and causing performance issues. This can occur due to improper priming, suction line leaks, or a loss of water supply. In this article we discuss about jet pump air lock and how to remove it.
What Is the Air Lock On a Jet Pump
Jet pump air blockage refers to a situation where air becomes trapped in the pump or the suction line, preventing the pump from effectively priming or causing disruptions in the water flow. It occurs when air accumulates in the system, hindering the pump’s ability to draw water and resulting in reduced or no water flow.
Air locks can occur in jet pumps due to several reasons, including improper priming, a leak in the suction line, or a loss of water supply. When an air lock occurs, the pump may struggle to create the necessary pressure differential to draw water, and instead, it pulls in air, leading to poor performance or complete pump failure. How do you remove an airlock from a jet pump To remove an airlock from a jet pump and resolve air-related issues, follow these steps:
1. Check Priming: Ensure that the pump is properly primed according to the manufacturer’s instructions. If the pump is not fully primed, it may not be able to create the necessary pressure to remove the airlock.
2. Open Air Release Valves: Some jet pump systems have air release valves installed. Open these valves to release trapped air from the system. Allow the pump to run while the valve is open to purge the air.
3. Check Suction Line: Inspect the suction line for any leaks, cracks, or loose fittings. Air can enter the system through these openings, causing airlocks. Repair any leaks or replace damaged components to ensure a sealed suction line.
4. Vent the System: If the airlock persists, you can manually vent the system by temporarily disconnecting the discharge pipe from the pump. Let the pump run for a few seconds to force out any trapped air. Once water flows consistently, reconnect the discharge pipe.
5. Increase Water Supply: Insufficient water supply can contribute to the formation of airlocks. Check if the water source is providing an adequate flow. If necessary, increase the water supply to help flush out the air and restore proper operation.
6. Re-prime the Pump: If all else fails, repeat the priming process. Fill the pump and suction line with water to displace any remaining air. Follow the manufacturer’s instructions for proper priming procedure.
Jet Pump Air Problem
A common air problem in a jet pump occurs when air becomes trapped in the pump or the suction line, leading to reduced or no water flow. This can result in poor pump performance or complete pump failure. Some common causes of jet pump air problems include:
1. Improper Priming: If the pump is not properly primed during installation or after maintenance, air can remain trapped in the system, hindering water flow.
2. Suction Line Leaks: Leaks or cracks in the suction line can allow air to enter the system, causing airlocks. Inspecting and repairing any suction line leaks is crucial in preventing air problems.
3. Loss of Water Supply: If the water source experiences a loss of supply or if there is insufficient water available, the pump may draw in air instead of water, leading to airlock issues.
Removing an Airlock in a Jet Pump
At first, ensure the pump is properly primed and that air is expelled from the system. Follow these steps:
1. Turn Off the Pump: Switch off the pump to prevent damage caused by running it without water.
2. Check the Inlet and Outlet: Inspect the inlet and outlet pipes for blockages or leaks. Tighten any loose connections.
3. Prime the Pump: Open the priming plug or valve located on the top of the pump. Pour water into the pump housing until it is full. This removes trapped air and fills the pump with water.
4. Bleed Air from the System: Locate any bleed valves in the system (usually on the pump or near the pipes). Open the valve and allow air to escape until water flows steadily, then close it.
5. Restart the Pump: Turn the pump back on. Listen for smooth operation and check for steady water flow. If the pump is still not working correctly, repeat the priming process.
6. Inspect for Persistent Issues: If airlocks continue to occur, check for leaks in suction lines or faulty check valves, which might allow air into the system.
This process should resolve most airlock issues in a jet pump. If the problem persists, you can consult a professional expert at Famcocorp to diagnose the system further.
Conclusion
An airlock in a jet pump occurs when air becomes trapped in the pump or suction line, resulting in reduced or no water flow. Common causes include improper priming, suction line leaks, or loss of water supply. To resolve an airlock issue, steps such as checking priming, inspecting the suction line, venting the system, and verifying the water supply should be taken. Regular maintenance and proper installation practices are essential in preventing airlocks in jet pumps. If the problem persists, consulting a professional or contacting the manufacturer is advisable for further assistance.
