The pressure-sensitive plugs are calibrated to hold water up to a certain pressure level which is higher than normal ground water pressure. Once the pore water pressure is increased to higher than that level due to an earthquake, the plugs will be released into the manhole and the water from the surrounding soils can be drained into the manhole ...
The reduction length is usually equal to the average of the larger and smaller pipe diameters. Although reducers are usually concentric, eccentric reducers are used as needed to maintain the top- or bottom-of-pipe level. A reducer can also be used either as a nozzle or diffuser, depending on the mach number of the flow. [citation needed]
