Pride Plumbing was called out for several toilets in the women’s bathroom not flushing correctly. Building maintenance let us know that the 2nd, 3rd & 4th toilets were having issues. We were able to turn up the 2nd & 4th toilets' Zurn flushometers and got them to flushing better. The 3rd toilet's flushometer was leaking from its vacuum breaker tube. Maintenance had overtightened the slip nut and ruined the vacuum breaker tube. We were able to replace the O-ring and the vacuum breaker and stopped the leak.
