commercial style toilet keeps flushing, and flushing...

Our old (I think 60's) American Standard, commercial style toilet (where there is no tank, but the flush valve is plumbed directly out of the wall) will frequently start flushing and run for several minutes before finally closing off and stopping. Once it stops, it refills just fine. It must be a sticky valve, or ring, but where? And how do I get to it? Must I replace the entire flush valve apparatus? They're like, $150.00! I'd love to dig into this thing and DIY it, I just need a place to start. Any suggestions?

I believe the problem in your commercial flush valve
(aka Flushometer) is caused by a hole in the diaphram (No, we are not talking about family planning devices!)
The diaphram controls the flow of water into the commerial toilet the same way a flush valve does in a regular toilet
The diaphram can be replaced for about $15
The following link may be helpful, if not try googling
the brand name which should be stamped on the flushometer
