Technician was originally called for what customer believe to be a faulty wax seal at the base of the toilet, however upon closer inspection technician found that the toilet was leaking from the tank to bowl gasket. Tech gave customer options and customer opted to have the gaskets replaced. Once work was complete tech turned on toilet and tested numerous times to ensure that there was no longer a week and toilet was properly functioning. Customer asked tech to look at a toilet while he was on site,He explained that the toilet would periodically run on it on. Tech explained to customer, that due to the age of the internal parts, as well as the quality of the water, toilet was in need of a new fill valve as well as a new flapper. Upon completion of the rebuild toilet was tested and is functioning properly.
