In response to Re: sloan valves and air pressure
These tanks were installed at least in the 1970's and as far as I know always worked before. Our water pressure appears to be ok in all of our faucets. It is just this weird phenomena of air bubbles shooting up from the bowl when they are flushed. It only happens on the commodes with sloan valves, and it does not happen if you just pour a five gallon bucket of water down into the commode. Only when they are flushed. It happens in all four commodes with sloan valves.


: : 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.

: : Thanks!

: Am I corrent to understand that you are experiencing excessive pressure on the flush valve toilets and not the tank type toilets?
: Am I also correct to understand that these toilets worked correctly for many years before this joint problem occurred? If so is it possible you have an expansion tank?
: Flush valves require more volume and pressure than tank types. In retro fitting flush valves into an existing system that is too small, an expansion tank will allow these valves to work. LonnythePlumber
