013 – PVC Distribution

Air is distributed from the pump via ordinary plumbing PVC pipes. Shown at the right are 3/4 inch PVC pipes, drilled with a small diagram hole. Cheap plastic airline valves are inserted into the holes and tubing attached. The PVC tubing is attached to the wood with electrician’s clamps.

PVC piping is easy to work with. Cement is used to unite pieces and to attach corner joints. It should be at least 3/4″ in diameter to allow air to travel through the system unimpeded. A 1″ system will increase the number of tanks you can support.

The key to installing a PVC system is the way you let out the path for the air. Essentially the air should travel in a loop back to the pump, rather than be distributed in a tree-like structure with dead ends. Creating a loop ensures that the air pressure is equal throughout the system. This will save you the trouble of trying to adjust the pressure at individual points along the way.
