Upon arrival I was shown to a toilet leaking from the tank. As I inspected it i noticed cracks on the tank and advised against rebuilding a toilet in this condition. I also found a seized emergency shutoff valve dedicated to this toilet and the main valve was an old gate valve. Informed the customer of the seized Valve and the risk and unreliability of the old gate style valves. An estimate to replace the main and emergency shutoff valve as well as the toilet was signed as well as an $800 deposit. Customer will schedule a stack shutdown and inform us on the day so we can come do the work
