The process for troubleshooting a Sloan Flushmate pressure assist toilet depends on what problem it is experiencing. Some of the common problems include the water continuing to run and not shutting off, weak or inconsistent flushing, no flush and a leaky vacuum breaker.
If the water continues to run, it could be caused by insufficient water pressure, a clogged inlet screen or an improperly adjusted flush valve cartridge. To troubleshoot this problem, first check to see that there is sufficient water pressure. If there is sufficient water pressure, move on to checking to see that the actuator is properly adjusted and is not interfered with by the push button or flush rod. Next, turn off the water supply, flush the toilet to remove the pressure and then check to see if the inlet screen is clogged. If the problem still persists, it may be necessary to remove, examine and reinstall or replace the flush valve cartridge.
These same steps can be used to troubleshoot a Flushmate that has problems with weak, inconsistent, sluggish or no flush. If none of these steps fixes the problem, it is then necessary to check the air inducer for damage or an obstruction.
If the vacuum breaker is leaking, check to see that there is sufficient water pressure and that the inlet screen is not clogged, as these are the primary causes of this problem.
