How to Remove Water from an Air Compressor Tank?

To remove water from an air compressor tank, you'll need to drain it using the drain valve.

Here's a step-by-step guide based on information in the provided reference video:

Steps to Drain an Air Compressor Tank

Preparation:
- Locate the drain valve at the bottom of your air compressor tank.
- Position a container, such as a pot, underneath the valve to catch the drained water.
- If the valve is difficult to access, prop the pot up to ensure it is properly positioned.
Draining the Water:
- Carefully and slowly undo the valve.
- The water should begin to flow out.
- Once the water has been drained, wipe a little bit of grease around the O-ring of the drain valve to ensure a good seal in the future, as suggested in the video at 0:59.
Post-Drainage:
- Ensure the drain valve is completely closed.
- You should periodically drain your air compressor tank to prevent excessive water accumulation, which can cause rust and reduced efficiency.

Frequency: Drain your compressor after each use, or at least daily if used regularly, to prevent water buildup.
Valve Inspection: Periodically check the drain valve for any damage or leaks. A little grease around the O-ring of the valve can help ensure it is working correctly.
Air Compressor Location: If possible, position your air compressor in an environment with stable temperature and low humidity. This can minimize condensation buildup.
Inline Filter: Consider installing an inline filter to separate water from the compressed air before it enters your tools and equipment.

Prevents Corrosion: Water accumulation can lead to rust and corrosion inside the tank, significantly reducing its lifespan.
Maintains Efficiency: Water in the tank can reduce the compressor's capacity, causing it to work harder and consume more energy.
Protects Tools: Water in the air line can damage your tools and equipment, causing malfunctions and potentially costly repairs.

By following these steps, you can effectively remove water from your air compressor tank and ensure its longevity and proper operation.
