2. Pressure-balanced valve - Wikipedia

   en.wikipedia.org/wiki/Pressure-balanced_valve

   If, for example, someone flushes a toilet while the shower is in use, the fixture suddenly draws a significant amount of cold water from the common supply line, causing a pressure drop. In the absence of a compensating mechanism, the relatively higher pressure in the hot water supply line will cause the shower temperature to rise just as ...

3. Tap (valve) - Wikipedia

   en.wikipedia.org/wiki/Tap_(valve)

   Also, the tortuous S-shaped path the water is forced to follow offers a significant obstruction to the flow. For high pressure domestic water systems this does not matter, but for low pressure systems where flow rate is important, such as a shower fed by a storage tank, a "stop tap" or, in engineering terms, a "gate valve" is preferred.

4. Drain-waste-vent system - Wikipedia

   en.wikipedia.org/wiki/Drain-waste-vent_system

   In the U.S., every plumbing fixture must also be coupled to the system's vent piping. [1] Without a vent, negative pressure can slow the flow of water leaving the system, resulting in clogs, or cause siphonage to empty a trap. The high point of the vent system (the top of its "soil stack") must be open to the exterior at atmospheric pressure.

5. Shower - Wikipedia

   en.wikipedia.org/wiki/Shower

   A shower head. A shower head is a perforated nozzle that distributes water over solid angle a focal point of use, generally overhead the bather. A shower uses less water than a full immersion in a bath. Some shower heads can be adjusted to spray different patterns of water, such as massage, gentle spray, strong spray, and intermittent pulse or ...

6. Riser clamp - Wikipedia

   en.wikipedia.org/wiki/Riser_clamp

   Riser clamp for a standpipe through-penetration firestop inside a fire hose cabinet under construction. A riser clamp is a type of hardware used by mechanical building trades for pipe support in vertical runs of piping (risers) at each floor level. The devices are placed around the pipe, and integral fasteners are then tightened to clamp them ...

7. Plumbing - Wikipedia

   en.wikipedia.org/wiki/Plumbing

   Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses pipes , valves , plumbing fixtures , tanks , and other apparatuses to convey fluids. [ 1 ] Heating and cooling (HVAC), waste removal , and potable water delivery are among the most common uses for plumbing, but it is not limited to these applications. [ 2 ]
