Hand auger / hand spinner Hand augers are useful for clearing sink and bathtub drains.
(A 1?4-inch cable, for example, should never be used in a drain with a calibre of more than two inches.) Closet auger / toilet auger The closet auger (named after water closet) feeds a relatively short auger through a hook-shaped length of metal tubing.
The hook shape makes it easier to feed the auger into the toilet.
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. However, in the case of schools you need to equip the bathroom in the right amount of sinks, where you will be able to wash their hands after using the toilet.
In schools, sports can also stand up showers.
An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 90° or 45° angle, though 22.5° elbows are also made. The ends may be machined for butt welding, threaded (usually female), or socketed, etc. When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow. Elbows are categorized based on various design features as below: Long Radius (LR) Elbows ? radius is 1.5 times the pipe diameter Short Radius (SR) Elbows ? radius is 1.0 times the pipe diameter 90 Degree Elbow ? where change in direction required is 90° 60 Degree Elbow ? where change in direction required is 60° 45 Degree Elbow ? where change in direction required is 45° A 90 degree elbow is also called a "90 bend" or "90 ell". It is a fitting which is bent in such a way to produce 90 degree change in the direction of flow in the pipe.It is used to change the direction in piping and is also sometimes called a "quarter bend".A 90 degree elbow attaches readily to plastic, copper, cast iron, steel and lead.
It can also attach to rubber with stainless steel clamps.It is available in many materials like silicone, rubber compounds, galvanized steel, etc. The main application of an elbow (90 degree) is to connect hoses to valves, water pressure pumps, and deck drains.These elbows can be made from tough nylon material or NPT thread.Źródło: https://en.wikipedia.org/wiki/Piping_and_plumbing_fitting.
