Hi reader in the U.S., it seems you use Wikipedia a lot; that's great! It's a little awkward to ask, but this Thursday we need your help. If you have already donated, we sincerely thank you. We’re not salespeople, but we depend on donations averaging $16.36 and fewer than 1% of readers give. If you donate just $2.75, the price of your coffee this Thursday, Wikipedia could keep thriving. Thank you.

Apprentice plumber: Apprenticeship programs generally provide the most comprehensive training for novice plumbers. Either union locals and their affiliated companies or nonunion contractor organizations can administer this training. Apprenticeships typically consist of at least three to four years of paid, on-the-job training and some hours of related classroom instruction.

“Don’t go to the Yellow Pages to find a plumber,” says Berkey’s Bill Stevens. “It’s like guessing lottery numbers. Anyone can make an appealing ad, but that doesn’t mean they are legitimate. In this industry, it’s easy for a plumber who develops a poor reputation to advertise under a different name. They come and go.” Even searching for someone online may end up being a scam using fake reviews. Instead, look for a plumber who is well-established in your community. Check the Better Business Bureau and read customer reviews at sites such as HomeAdvisor, Angie’s List, or Citysearch. Local contractors or plumbing fixture stores can also refer you to a quality plumber, according to Grady Daniel, who owns a plumbing company in Austin, Texas. “Most of these firms won’t work with bad plumbers.” Or simply ask your neighbors for a referral. A trusted plumber that consistently delivers quality service does not remain a secret for very long.


Wall thickness does not affect pipe or tubing size.[20] 1/2" L copper has the same outer diameter as 1/2" K or M copper. The same applies to pipe schedules. As a result, a slight increase in pressure losses is realized due to a decrease in flowpath as wall thickness is increased. In other words, 1 foot of 1/2" L copper has slightly less volume than 1 foot of 1/2 M copper.[citation needed]
Wooden pipes were used in London and elsewhere during the 16th and 17th centuries. The pipes were hollowed-out logs, which were tapered at the end with a small hole in which the water would pass through.[16] The multiple pipes were then sealed together with hot animal fat. They were often used in Montreal and Boston in the 1800s, and built-up wooden tubes were widely used in the USA during the 20th century. These pipes, used in place of corrugated iron or reinforced concrete pipes, were made of sections cut from short lengths of wood. Locking of adjacent rings with hardwood dowel pins produced a flexible structure. About 100,000 feet of these wooden pipes were installed during WW2 in drainage culverts, storm sewers and conduits, under highways and at army camps, naval stations, airfields and ordnance plants.
