I need a blue print on how a sloan urinal flush valve works and how the water flowes through it. if posable exactly how it works.

SLOAN FLUSH VALVES ARE SIMPLE. IT DEPENDES ON THE PROBLEM. IF THE VALVE KEPS RUNNING AFTER IT IS FLUSHED THE RUBBER DIAPHRAM IS DIRTY OR OLD AND THE RUBBER DIAPHRAM IS GETTING HARD. AND STICKING. THE VALVE WORKS ON A VACUME TO CLOSE THE DIAPHRAM TO STOP THE FLUSH PROCESS. WHEN YOU PULL ON THE FLUSH HANDLE YOU BREAK THE VACUME THAT FORM ON THE TOP OF THE DIAPHRAM WHICH ALLOWS THE WATER TO FLOW AS THE WATER FLOWS IT IS ALSO STARTING TO PULL A VACUME IN THE TOP OF THE DIAPHRAM TO CLOSE THE DIAPHRAM AND STOP THE FLUSH.
AS THE DIAPHRAM GET OLD AND WORN IT GETS HARD AND DOES NOT MOVE AS FREELY AND STICKS OPEN AND WON'T LET THE VACUME CLOSE THE DIAPHRAM AND THE URINAL WILL CONTINUE TO FLUSH. HOPE THIS ANSWERED YOU QUESTION
