Customer stated that urinal in men’s room wasn’t flushing properly. Replace diaphragm with bigger diaphragm and tested. Now urinal seems to be flushing as it should. Also tested drained by filling up bucket of water and dumping it down urinal multiple times and urinal was draining. Stated to customer that urinal may be flushing differently. Due to the fact there is the pad inside the urinal. Also flushed the rest of toilets in unit and all seem to be flushing as they should.
