Valuation of hydraulic damage caused in the apartment
A very common problem faced by owners of apartments and houses are damages caused by various hydraulic failure. The cause of such failures in the apartments are leaking hose from the washing machine or cracked seals in taps or faulty cam. For similar accidents could occur in homes where often there are also problems associated with the lack of patency in the sewer pipes.
Sometimes it happens that the hydraulic failures give rise to really serious damages mainly related to flooding different rooms.
A precise measurement of the damage will plan all the necessary repairs and their efficient execution. Thus, you can also select the appropriate plumbing materials and do the whole job at a reasonable price.
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.Źródło: https://en.wikipedia.org/wiki/Piping_and_plumbing_fitting
About water supply and sanitation
Water supply and sanitation has been a primary logistical challenge since the dawn of civilization. Where water resources or infrastructure or sanitation systems are insufficient for the population, people fall prey to disease, dehydration, and in extreme cases, death.
Major human settlements could initially develop only where fresh surface water was plentiful, such as near major rivers.
Over the millennia, technology has dramatically increased the distances across which water can be relocated, but the availability of clean and fresh water remains a limiting factor on the size and density of population centers, and is expected to remain so into the foreseeable future.Źródło: https://en.wikipedia.org/wiki/History_of_water_supply_and_sanitation.
