Pro Plumbers

My parents are in their middle eightys and my mother is at home with cancer. They live in SaintAugustine Florida.My problem is their two toilets will not flush all the way down the drain. I. have been down there twice to help them but I cannot drive 1200 miles each time they have a problem.So for now I would like to know what I can translate to my father over the phone to remedy this situation. Thank you very much Ray Dupuis.
The word "plumber" dates from the Roman Empire.[3] The Latin for lead is plumbum. Roman roofs used lead in conduits and drain pipes[4] and some were also covered with lead, lead was also used for piping and for making baths.[5] In medieval times anyone who worked with lead was referred to as a plumber as can be seen from an extract of workmen fixing a roof in Westminster Palace and were referred to as plumbers "To Gilbert de Westminster, plumber, working about the roof of the pantry of the little hall, covering it with lead, and about various defects in the roof of the little hall".[6] Thus a person with expertise in working with lead was first known as a Plumbarius which was later shortened to plumber.
