A sink?also known by other names including sinker, washbowl, hand basin and wash basin?is a bowl-shaped plumbing fixture used for washing hands, dishwashing, and other purposes.
Sinks have taps (faucets) that supply hot and cold water and may include a spray feature to be used for faster rinsing.They also include a drain to remove used water; this drain may itself include a strainer and/or shut-off device and an overflow-prevention device.
Sinks may also have an integrated soap dispenser. When a sink becomes stopped-up or clogged, a person will often resort to use a chemical drain cleaner or a plunger, though most professional plumbers will remove the clog with a drain auger (often called a "plumber's snake").Źródło: https://en.wikipedia.org/wiki/Sink
Types of leak openings include a puncture, gash, rust or other corrosion hole, very tiny pinhole leak (possibly in imperfect welds), crack or microcrack, or inadequate sealing between components or parts joined together.
When there is a puncture, the size and shape of the leak can often be seen, but in many other cases, the size and shape of the leak opening may not be so obvious.In many cases, the location of a leak can be determined by seeing material drip out at a certain place, although the leak opening itself is not obvious.In some cases, it may known or suspected there is a leak, but even the location of the leak is not known.Since leak openings are often so irregular, leaks are sometimes sized by the leakage rate, as in volume of fluid leaked per time, rather than the size of the opening. Common types of leaks for many people include leaks in vehicle tires, causing air to leak out resulting in flat tires, and leaks in containers, spilling the contents.Leaks can occur or develop in many different kinds of household, building, vehicle, marine, aircraft, or industrial fluid systems, whether the fluid is a gas or liquid.Leaks in vehicle hydraulic systems such as brake or power steering lines could cause outleakage of brake or power steering fluid resulting in failure of the brakes, power steering, or other hydraulic system.
Also possible are leaks of engine coolant - particularly in the radiator and at the water pump seal, transmission fluid, motor oil, and refrigerant in the air conditioning system.Some of these vehicle fluids have different colors to help identify the type of leaking fluid.
