Pride Plumbing was called out for two Kohler toilets not flushing properly. For the first toilet, we found that the issue was being caused by the unit’s Sloan Flushometer flush valve. We used a Sloan 3317003 Regal rebuild kit and rebuilt the flush valve (replacing the diaphragm, vacuum breaker, and control stop). For the second toilet, there was an issue with its Sloan autoflush mechanism and its Sloan Flushometer flush valve. We first repaired the autoflush mechanism, and then used a Sloan 3317004 Regal rebuild kit and rebuilt the flush valve (replacing the diaphragm, vacuum breaker, and control stop).
