This invoice was to provide and install two Sloan fluorometer valves with emergency stop shut off one located on the fourth floor and one located on the fifth floor. The original invoice was for only the fourth floor, but when we were pressuring the system, I was flushing all the toilets to get the air out and the fifth floor was leaking. Matt is the one that discovered it and he shut it off and asked us to change it so I added it to this bill. Upon completion of project, Matt and I walked all floors and flushed all toilets urinal, and turned on all faucets to verify everything is working properly. We also changed out two emergency stops for the sixth floor kitchen sink. I also provided estimate to replace Sloan flush valve with emergency stop on second floor urinal.
