2. Low-flow fixtures - Wikipedia

   en.wikipedia.org/wiki/Low-flow_fixtures

   Low-flow kitchen faucets can cause the filling of a pot to take a long time. In addition, performance issues with low-flow faucets often pertain to their ability to properly rinse or wet. In the United States the EPA's WaterSense has established minimum flow rates for lavatory fixtures to ensure satisfaction with low water pressures. [20]

3. Tap (valve) - Wikipedia

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

   Faucet is the most common term in the US, similar in use to "tap" in British English, e.g. "water faucet" (although the term "tap" is also used in the US). Spigot is used by professionals in the trade (such as plumbers), and typically refers to an outdoor fixture.

4. Faucet aerator - Wikipedia

   en.wikipedia.org/wiki/Faucet_aerator

   When an aerator is added to the faucet (or fluid stream), there is a region of high pressure created behind the aerator. Because of the higher pressure behind the aerator and the low pressure in front of it (outside the faucet), due to Bernoulli's principle there is an increase in velocity of the fluid flow.

5. Air gap (plumbing) - Wikipedia

   en.wikipedia.org/wiki/Air_gap_(plumbing)

   To further illustrate the air gap, consider what could happen if the air gap were eliminated by attaching a hose to the faucet and lowering the hose into a sink full of contaminated water. Under the right conditions (if the water supply loses pressure and the sink is higher than the point at which the water supply enters the house, for instance ...

6. Atmospheric vacuum breaker - Wikipedia

   en.wikipedia.org/wiki/Atmospheric_vacuum_breaker

   An Atmospheric Vacuum Breaker (AVB) is a backflow prevention device used in plumbing to prevent backflow of non-potable liquids into the drinking water system.. Diagram of Atmospheric Vacuum Breaker in both working states.

7. Recoil operation - Wikipedia

   en.wikipedia.org/wiki/Recoil_operation

   Block diagram of inertia operation cycle, see diagram key above. As the recoil spring returns to its uncompressed state, it pushes the bolt body backward with sufficient force to cycle the action. The bolt body unlocks and retracts the bolt head, extracts and ejects the cartridge, cocks the hammer, and compresses the return spring.

8. Pressure-balanced valve - Wikipedia

   en.wikipedia.org/wiki/Pressure-balanced_valve

   Conversely, if someone opens a hot water faucet elsewhere, the relatively higher pressure in the cold water supply line will cause the shower temperature to drop suddenly. This is described in US patent 3674048. [1] The pressure-balanced shower valve compensates for changes in water pressure.

9. Syringe - Wikipedia

   en.wikipedia.org/wiki/Syringe

   It is practically a bottomless flask. The latter is replaced by an elastomer plug that can slide in the body of the cartridge. This plug will be pushed by the plunger of the syringe. The neck is closed with a rubber cap. The dentist places the cartridge directly into a stainless steel syringe, with a double-pointed (single-use) needle. The tip ...
