The thicknesses of the water pipe and tube walls can vary. Pipe wall thickness is denoted by various schedules or for large bore polyethylene pipe in the UK by the Standard Dimension Ratio (SDR), defined as the ratio of the pipe diameter to its wall thickness. Pipe wall thickness increases with schedule, and is available in schedules 20, 40, 80, and higher in special cases. The schedule is largely determined by the operating pressure of the system, with higher pressures commanding greater thickness. Copper tubing is available in four wall thicknesses: type DWV (thinnest wall; only allowed as drain pipe per UPC), type 'M' (thin; typically only allowed as drain pipe by IPC code), type 'L' (thicker, standard duty for water lines and water service), and type 'K' (thickest, typically used underground between the main and the meter). Because piping and tubing are commodities, having a greater wall thickness implies higher initial cost. Thicker walled pipe generally implies greater durability and higher pressure tolerances.

Most plumbers, pipefitters, and steamfitters learn their trade through a 4- or 5-year apprenticeship. Apprentices typically receive 2,000 hours of paid on-the-job training, as well as some classroom instruction, each year. In the classroom, apprentices learn safety, local plumbing codes and regulations, and blueprint reading. They also study mathematics, applied physics, and chemistry. Apprenticeship programs are offered by unions and businesses. Although most workers enter apprenticeships directly, some start out as helpers. The Home Builders Institute offers a pre-apprenticeship training program in plumbing and other trades.
Wall thickness does not affect pipe or tubing size. 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.
Although plumbers, pipefitters, and steamfitters perform three distinct and specialized roles, their duties are often similar. For example, they all install pipes and fittings that carry water, steam, air, or other liquids or gases. They determine the necessary materials for a job, connect pipes, and perform pressure tests to ensure that a pipe system is airtight and watertight. Their tools include drills, saws, welding torches, and wrenches.
To work independently, a plumber is required to receive a license. In most states, the prerequisite for earning this license is two to five years of practical experience. There's also an exam to test technical know-how and understanding of plumbing codes. The United Association's website offers extensive information on licensing requirements by state.

Cast iron and ductile iron pipe was long a lower-cost alternative to copper, before the advent of durable plastic materials but special non-conductive fittings must be used where transitions are to be made to other metallic pipes, except for terminal fittings, in order to avoid corrosion owing to electrochemical reactions between dissimilar metals (see galvanic cell).
No plumber is going to come right out and explain that they don’t have the required license to work for you. So if you know someone who is a great plumber, but they don’t have a license, hire them at your own risk. Licensed plumbers know the local building codes and regulations, have completed a certain amount of hours on the job and are insured. Want to become a master plumber yourself? Here are 28 tips.
I needed a neutral place to research plumbing jobs: had the suspicion I was being 'led down a garden path' because I knew nothing - other than how expensive it was and how urgent 'do it NOW!" it was. I appreciate the cost estimate and national average pages which confirmed my suspicions. I found another plumber through this site and hope for better, less panic, less cost service from now on. Thanks.
Plumbers install and repair water, drainage, gas, and other piping systems in homes, businesses, and factories. Plumbers install plumbing fixtures such as bathtubs and toilets, and appliances, such as dishwashers and water heaters. Plumbers also maintain septic systems—the large, underground holding tanks that collect waste from houses that are not connected to a sewer system. Click Here for Plumber Repair Denver
