Microphor after flush...air leak -low pitched sound
#1

I have a conundrum.

My mid bath (the 1/2 bath one) is working fine. When flushed, it goes all the way through the cycle and when complete and bowl is refilled I get a low pitch "hum" which is definitely an air leak, but I cannot figure out where or how to fix it. I checked all the fittings internally and none are leaking. It may be from the spool? Maybe an o-ring when bad??

Any idea what would cause this AFTER a complete cycle. It drains my supply air system in minutes!

Of course we're on the road in Avon, NC. beautiful place albeit a bit on the small side. Pictures in the AM. If anyone is nearby, you are welcome to visit. We'll be here until Friday.

Thanks!!!!

Be seeing you,

The last step in the cycle is the pressurization of the hopper. Then the spool is supposed to close completely to stop the pressurization. Sounds like the spool is sticking.

Could be simple sticking, so a dozen or so flushes may free it up.

If not, take the spool valve apart and lube it lightly with plumbers silicone or o ring silicone. Lightly.

Richard,
Thanks! That's what I thought it was, and after a bunch of flushes it seems to be working now. Is there an easy way to pull the spool to check, clean, lube?

Thanks again!

I do not know of an easy way. The only method I know of requires the entire assembly to come out. The bottom screws off, and the spool exits the bottom. Taking the top cap off will not allow the spool to be removed.
