Air pump repair kit

Air pumps allow for proper gas exchange and water circulation in the saltwater aquarium. They are also used to power the sponge filters, the under-gravel filters, protein skimmers and corner box filters. Most of the time, they exhibit disturbing vibration noises caused by their movable parts and this is how to fix them.

 

 Step 1: Remove the Air Pump

To establish the defects, remove the bottom part of the air pump using the screwdriver.

Step 2: Inspect the Movable Parts

The air pump has three movable parts, namely the diaphragm, the magnetic arm, and the valve block. Inspect them for the following defects:

  • Diaphragm: It will be defective if it is loosely attached to the valve block.
  • Magnetic arm: Its hitting on the sides of the case while swinging shows that it is defective.
  • Valve block: It will be defective if it is wrongly seated in its slot.

Step 3: Correct the Defects

Attach the diaphragm tightly to the valve block using the screwdriver. Fix the magnetic arm in a way that it does not hit the sides of its case and clamp the valve block firmly in its slot.

 Step 4: Reattach the Air Pump

Reattach the bottom of the air pump after fixing the above defects. Ensure that you do it firmly using the screws to curb further noise problems.
