Upon arrival I was shown to two running toilets. The emergency shutoff valves were also seized and I informed the customer. An estimate to replace both emergency shutoff valves and do two minor rebuilds were agreed on and after the work was done I tested my connections for leaks and none were present and I flushed both toilets multiple times to ensure they were operating properly and no longer running. Highly recommend replacing the water heater due to age and since they are on the 11th floor and this can be a serious problem if the heater rusts out on the bottom and leaks down and creates and flood
