Releasing air pressure from a water pump, often referred to as removing an airlock, typically involves allowing trapped air to escape while ensuring water flow. While the provided reference discusses a specific "Water Pump Airlock Procedure" in the context of a boat, the general principles can be applied to other water pump systems.
Here's a general approach to releasing air pressure from a water pump:
-
Identify the Problem: Air can get trapped in a water pump system, preventing it from priming or pumping efficiently. This is known as an airlock.
-
Locate Bleed Points: Many water pump systems have bleed points or valves designed to release trapped air. These are often located at the highest points in the system.
-
Open Taps/Faucets: According to the provided reference, in the context of a boat water system, you should "go around to each of your taps." This allows air to escape through the faucets.
-
Loosen Connections: If there are no dedicated bleed points, carefully loosen a connection, such as a hose fitting on the output side of the pump, to allow air to escape. Be prepared for water to spray out.
-
Prime the Pump: Some pumps have a priming port. Remove the plug, fill the pump housing with water, and replace the plug. This helps the pump establish suction.
-
Run the Pump: Turn on the pump and allow it to run for a few minutes. The water flow should help to purge any remaining air.
-
Monitor: Check the pump's performance. If the pump is still not working correctly, repeat the above steps.
Example: Boat Water System (based on reference)
The provided reference describes a procedure for a boat water pump:
-
Output Hose: Ensure the output hose is easily inserted and clipped with the locking tab.
-
Open All Taps: "Go around to each of your taps" to allow air to escape while the pump runs.
Potential Causes of Airlocks
- Recent Maintenance: After working on the plumbing system.
- Dry Running: Allowing the pump to run without water.
- Leaks: Suction side leaks can draw air into the system.
