In our church, we have a strange phenomena. When we flush the sloan valve commodes, air is shooting up into the bowl, as well as water. It produces bubbles, and even some splashing. We have replaced one sloan valve, and it made no difference. We had the drain lines cleaned by roto rooter and it made no difference.
We do have a a backflow valve on the entire water system.
We have not observed air in any other water faucets, or other commodes that have a regular tank.
