The general process for bleeding a water tank pump involves opening a bleed valve or port to release trapped air from the system until only water flows out.
Here's a breakdown of the process:
-
Identify the Bleed Valve/Port: Locate the bleed valve or port on your pump. It's often a small valve or screw located on the pump housing or near the pressure gauge. Consult your pump's manual if you're unsure where it is.
-
Prepare for Water Release: Have a container (bucket, bowl, etc.) and rags ready to catch the water that will be released during the bleeding process.
-
Open the Bleed Valve/Port: Slowly open the bleed valve or port. You may need a wrench or screwdriver, depending on the type of valve.
-
Release Air: Listen for the sound of air escaping. You will likely hear hissing and see air bubbles mixed with water.
-
Wait for Water: Continue to allow the air to escape until a steady stream of water flows out without any air bubbles.
-
Close the Bleed Valve/Port: Once only water is flowing, carefully close the bleed valve or port tightly. Avoid over-tightening, which could damage the valve.
-
Check the Pump: Turn on the pump and observe its operation. It should now run smoothly and deliver water without sputtering or air pockets.
-
Repeat if Necessary: If the pump still exhibits signs of air in the system (e.g., fluctuating pressure, noisy operation), repeat the bleeding process.
Important Considerations:
- Power: In some cases, it is helpful to turn the pump on and off during this process to help air work its way out of the system.
- Safety: Ensure the pump is properly grounded. Be careful when working with electrical components and water.
- Manual: Always refer to the manufacturer's instructions for your specific pump model.
