Hydraulic shock (colloquial: water hammer; fluid hammer) is a pressure surge or wave caused when a fluid in motion is forced to stop or change direction suddenly: a momentum change. It is usually observed in a liquid but gases can also be affected.
The mechanism of a flushing trough: pulling the flush chain (1) rocks the flush lever (2) and lifts the siphon plate (3), forcing water over the top of the siphon (4) and starting the flush. Water is sucked through a connecting pipe (5) from the timing box (6) and air enters the timing bottle through the vent pipe (7) until the box is empty and ...
These devices avoid negative pressure in the drain pipe by venting room air into the drain pipe (behind the trap). A "Chicago Loop" is another alternative. When a trap is installed on a fixture that is not routinely used—such as a floor drain—the eventual evaporation of the water in the trap must be considered.
How toilet water sprays when we flush - carrying potentially deadly germs into the air - has been revealed in a series of experiments.Scientists say the 'invisible plume' - containing microscopic ...
A flush toilet (also known as a flushing toilet, water closet (WC); see also toilet names) is a toilet that disposes of human waste (i.e., urine and feces) by collecting it in a bowl and then using the force of water to channel it ("flush" it) through a drainpipe to another location for treatment, either nearby or at a communal facility.
A narrow passageway leads from the main water supply into the pressure chamber. It is the narrowness of this passage that meters the flow by slowing repressurizing of the pressure chamber after the action of a flush. The diaphragm technology allows the flush valve to open and let water into the bowl. A main cylinder valve operates up and down.
A plumber's snake or drain snake or drain auger is a slender, flexible auger used to dislodge clogs in plumbing. The plumber's snake is often reserved for difficult clogs that cannot be loosened with a plunger. It is also sometimes called a toilet jack. A plumbers snake is often used by plumbers to clear a clogged drain pipe or sanitary sewer.
Hydropneumatic water hammer preventers are chambers of sufficient volume to allow an extension of time in which a given flow may be accelerated or decelerated without sudden large change in pressure. See also expansion tank. When shock waves of an incompressible fluid within a piping system exist, especially at a high velocity, there is a high ...
