“I have used Central Penn for many repairs/installs over the last 15 years. They have always responded in a prompt manner and I found their people to be very friendly, efficient and competent in diagnosing and repairing any issues I had, whether related to plumbing or HVAC. Furthermore, which you can’t take for granted these days, the guys are very respectful of your home and are careful in their work and thoroughly clean up after the job is completed.”
The word "plumber" dates from the Roman Empire. The Latin for lead is plumbum. Roman roofs used lead in conduits and drain pipes and some were also covered with lead, lead was also used for piping and for making baths. 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". Thus a person with expertise in working with lead was first known as a Plumbarius which was later shortened to plumber.
