To build this device, a bulkhead fitting was placed at the base of a 5 gallon bucket, then clear PVC tubing was inserted in the bulkhead and coiled twice around the frame. The coils trap air and water. As the bucket is filled, the height of the water of the bucket finally gets strong enough to blow the air bubbles and water out of the way. It then drains until there is not enough water in the bucket to displace the air. We are using a pump to recycle the water through a garden hose back to the first bucket for testing purposes.
