2. Isolation valve - Wikipedia

   en.wikipedia.org/wiki/Isolation_valve

   However, if the spigot needs to be replaced (i.e. maintenance needs to take place on the system), the isolation valves are shut to stop the flow of water when the spigot is removed. In this system, the isolation valves and the spigot may even be the same type of valve.

3. Low-flow fixtures - Wikipedia

   en.wikipedia.org/wiki/Low-flow_fixtures

   Leaking fixtures can contribute to significant water waste. According to the EPAs WaterSense, a leaky faucet that drips at a rate of one drip per second can waste more than 3,000 gallons of water per year. [21] Old and worn out rubber valve seals in a toilet tank can lead to significant leaks causing the toilet to refill constantly. Some leaky ...

   Spigot is used by professionals in the trade (such as plumbers), and typically refers to an outdoor fixture. [1] Silcock (and sillcock), same as "spigot", referring to a "cock" (as in stopcock and petcock) that penetrates a foundation sill. Bib (bibcock, and hose bib or hosebibb), usually a freeze-resistant version of a "spigot".

5. Reduced pressure zone device - Wikipedia

   en.wikipedia.org/wiki/Reduced_pressure_zone_device

   Because certain combinations of check valve failure and/or system backpressure cause the relief valve to discharge, the device must be mounted in a location where the drain will not become flooded. An example of where backflow would harm the water supply is the use of well washing devices inside underground sewerage pumping stations.

6. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   Isolation valves temporarily disconnect part of a piping system to allow maintenance or repair, for example. Isolation valves are typically left in either a fully open or closed position. A given isolation valve may be in place for many years without being operated but must be designed to be readily operable whenever needed, including for ...

7. Air gap (plumbing) - Wikipedia

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

   In the base cabinet under the sink, the drain hose from the dishwasher feeds the "top" of the air gap, and the "bottom" of the air gap is plumbed into the sink drain below the basket, or into a garbage disposal unit. When installed and maintained properly, the air gap works as described above, and prevents drain water from the sink from backing ...

The Stillson wrench, or Stillson-pattern wrench, is the usual form of pipe wrench, especially in the US. The Stillson name is that of the original patent holder, who licensed the design ...

9. Damper (flow) - Wikipedia

   en.wikipedia.org/wiki/Damper_(flow)

   The system can be harder to a design, requiring both "SPDT" thermostats (or relays) and the ability of the system to withstand the fault condition whereby all zone dampers are closed simultaneously. Pneumatic actuation is preferred for these dampers. It is easier to provide zone-classified solenoid valves for pneumatic actuation, as compared to ...
