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".
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.
In areas where the air or surface ground temperatures reach below freezing point for part or all of the year, some standpipes are equipped with a feature whereby the same mechanism that valves the water for the bib also uncovers a drainage hole (the 'weep hole') at the base of the pipe when the standpipe is closed, ensuring that the column of water drains into the ground rather than remaining ...
Class V valves leak less than 5 × 10 −12 cubic metres, per second, per bar of pressure differential, per millimetre of port diameter, of water when tested at the service pressure. Class VI valves are slightly different in that they are required (at 50 psi (340 kPa) or operating pressure, whichever is less) to have less than a specified ...

Factors contributing to the leak were frost heave, mismatch of pipe ends, residual forces applied during clamping of the pipe replacement ends to the existing pipeline, unusually cold weather on the day of the rupture, and non-homogeneous material in the weld metal at the origin of the fracture that reduced effective thickness of the pipe wall.
