PBT – flexible (usually gray or black) plastic pipe which is attached to barbed fittings and secured in place with a copper crimp ring. The primary manufacturer of PBT tubing and fittings was driven into bankruptcy by a class-action lawsuit over failures of this system. However, PB and PBT tubing has since returned to the market and codes, typically first for "exposed locations" such as risers.
I had 207 Plumbing come to fix a leak in my ceiling. It's a terrible, terrible company to do business with. He came and fixed a broken pipe in the ceiling, and I asked him to check the rest of the pipe to make sure that nothing else was broken, he said everything was OK and charged me $219.00 for 45 minutes and left. Never cleaned up his mess. I went to clean up the mess after he left and found there was more damage to the pipe. I called him to come back, which he did. He looked at the water coming down from the ceiling, into a light fixture and said he had another job to go to and couldn't come back until next week. He also wanted to charge me $350.00 to come back. I told him that was too much and he said he would make an exception and only charge me $219.00. Now I have major damage done to the ceiling, the light fixture and the floor. All of this could have been prevented if he had stayed and fixed the problem. I will NOT hire him again.
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.
