Elbows - not only your body parts
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.
Types of plumber's snakes
Hand auger / hand spinner
Hand augers are useful for clearing sink and bathtub drains. They are unsuitable for sending through flush toilets, because the wire might damage the bowl; also, flush toilets have relatively large drain pipes in which the narrow snake can be become tangled. (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. A plastic boot on the end of the auger protects the finish of the visible porcelain. Since most toilet clogs occur in the trap built into the bowl, the short cable is sufficient to break up or retrieve the greater majority of clogs.
