Am I correct in assuming that the drain of a urinal equipped with a Sloan "sensor activated Flushometer" valve should be able to accept that valve failing in the open position and handle the full water flow without the urinal overflowing?
That didn't happen in our office building last night when a valve in the second floor mens room failed to close, the urinal overflowed and the floor drain also could not handle the continuous flow so the water went out under the bathroom door, spread into a couple of offices and then leaked down into several offices below, including mine.
Our landlord's maintenance manager called it "a perfect storm" and there have been workers here all day cleaning up the messes it caused.
Just for S&Gs (I guess I should say P&Gs)I tested the urinal in the first floor mens room a few minutes ago. I pushed the manual button on the top of the Flushometer valve as often as it would accept a push and watched the water level in the urinal continue to rise while I did that. I have no doubt that it would have overflowed had I continued, or the valve got stuck open.
The building is about 25 years old and I suspect that nobody gave much thought to testing the urinal and floor drain's capacities during that time, and most likely they were partially clogged. I hope they will in the future.
