The Romans used inverted siphons of lead pipes to cross valleys that were too big to construct an aqueduct. [41] [42] [43] Inverted siphons are commonly called traps for their function in preventing sewer gases from coming back out of sewers [44] and sometimes making dense objects like rings and electronic components retrievable after falling ...
This inverted siphon was used to draw the fire's hot fumes up the front and down the back of the Franklin stove's hollow baffle, in order to extract as much heat as possible from the fumes. The earliest known example of such an inverted siphon was the 1618 fireplace of Franz Kessler. [9] The fire burned in a ceramic box.
Inverted siphoning occurs below the line "A". Examples of traps In plumbing , a trap is a U-shaped portion of pipe designed to trap liquid or gas to prevent unwanted flow; most notably sewer gases from entering buildings while allowing waste materials to pass through.

A lift station is a sewer sump that lifts accumulated sewage to a higher elevation. They may also be used to prime an inverted siphon used to cross underneath rivers or other obstructions. The pump may discharge to another gravity sewer or directly to a treatment plant. [6]
Four inverted siphon tunnels cross the particularly deep and wide river valleys of the Durèze, the Garon, [4] the Yzeron and the Trion on pipe bridges raised on high arches. In these, water filled a sunken tank tower (castellum [5]) on the brim of a slope. The tank effected a transition between open channel flow and a lead pipeline.
Water cannot flow from the sink to the tap in normal circumstances, even if the water supply loses pressure. An air gap, as related to the plumbing trade, is the unobstructed vertical space between the water outlet and the flood level of a fixture. [1]
The system consists of about 83-mile (134 km) of buried concrete unpressurized conduit and 9.9-mile (16 km) of buried pressurized inverted siphons. Over its length the aqueduct crosses eight rivers. The conduit was built using the "cut and cover" method with an unreinforced concrete arch resting on a cast in place base invert.
