They can be rented during the construction of the house.They also participate in the process of putting up apartment buildings and schools of all sizes. It seems that the least complicated plumbing services are performed in the course of construction of the house, because they are limited to the performance of domestic water supply and sewage, and in the case of apartment blocks need to make a detailed plan of such a network adequate to the number and position of the individual apartments.
The difference between pipes and tubes is simply in the way it is sized.
Copper tube, CPVC, PeX and other tubing is measured nominally, which is basically an average diameter.
For instance, 1/2" PeX tubing is the same size as 1/2" copper tubing.
Tubing, in particular copper, comes in rigid hard tempered "joints" or soft tempered (annealed) rolls.PeX and CPVC tubing also comes in rigid "joints" or flexible rolls.
The temper of the copper, that is whether it is a rigid "joint" or flexible roll, does not affect the sizing.7 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.
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.Źródło: https://en.wikipedia.org/wiki/Water_pipe#Difference_between_pipes_and_tubes
Drum augers A drum auger is a motorized auger with modular blades designed for various gauges of pipe.Źródło: https://en.wikipedia.org/wiki/Plumber%27s_snake.A drum auger is powerful enough to cut through tree roots.Used unskillfully, they can also damage plastic pipework and even copper tubing. Roto-Rooter Main article: Roto-Rooter The Roto-Rooter is an electric auger invented in 1933 by Samuel Blanc, an American.His wife called the invention a Roto-Rooter, because the cable and blades rotated as they cut through tree roots inside sewer pipe.
Competing companies made imitations after the Blanc's patent expired in 1953, but the machine is manufactured by and for a United States company called the Roto-Rooter Plumbing & Drain Service.Źródło: https://en.wikipedia.org/wiki/Plumber%27s_snake
