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.
Water systems of ancient times relied on gravity for the supply of water, using pipes or channels usually made of clay, lead, bamboo, wood, or stone. Hollowed wooden logs wrapped in steel banding were used for plumbing pipes, particularly water mains. Logs were used for water distribution in England close to 500 years ago. US cities began using hollowed logs in the late 1700s through the 1800s. Today, most plumbing supply pipe is made out of steel, copper, and plastic; most waste (also known as "soil")[22] out of steel, copper, plastic, and cast iron.[22]

Needed to replace a water pressure regulator.  Looking at the retail costs of the regulator, they seem to run from abouit $60 to over $300 for one that includes more that the basic control of water pressure in the house.  Had not used a pro plumber for over 20 years so I was not up on the costs associated with needing their help.  I was contacted by at least 3 plumbers but only one, Right Now Plumbers, gave me an instant quote of $394  for the service without me even asking. Although I thought this price seemed a little high for a job that takes less than an hour to complete, I accepted their service.  Must say that the job was done very professionally and would use them again if needed.  However,
