Interesting toilet issue

[Fastrooter steve]

Hey gang,
So heres one for ya. I have a 3/4" main stepping up to 1½" to feed 2 slone flush valves on wall mount toilets in a retail store public restrooms.
There is a 10 gallon well tank installed at the top of this line as a expansion tank. Incoming pressure varies from 50 to 60 psi, dropping to 20 psi when either toilet is flushed. This set up works well at times.
So as you can guess the flush is not the greatest. I was wondering if anyone has any suggestions as to increase perfomance without any major overhauls to system?

Has this ever worked need 25 psi to have a flushometer work properly

Yes, its worked for quite awhile up untill yesterday, discovered a toilet in a vacant space next door with a stuck flapper. Now i cant recover pressure for full flush

So there is just one meter to my client, seen meter spinning, checked all fixtures, gained access to vacant space and discovered toilet running, and now we know that space share this meter. Pressure after prv and backflow is now 60 psi static

So know when you flush is the pressure dropping out????

Yea, flush toilet and pressure drops 20 to 30 for a moment. Was thinking of changing diaphram from 1.6 to 1.1

If new diaphragm does not fix it, maybe the prv is partially clogged or defective, limiting flow volume, but not static pressure.

Yup

Might be related somehow to all that water flow, while nearby toilet had stuck flapper.

You can check the screen in the prv it may be clogged

If it's a 1.6 leave it that way, it won't flush properly how old is the wall hung toilet
Do the flushometer parts match the gpf
