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 ...
Inverted siphoning occurs below the line "A". Examples of traps [ further explanation needed ] 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]
This runs along a mountainside for most of its 17 km (11 mi) route. When full, the water in the canal is 2.7 meters (8.9 ft) deep and flows purely by gravity apart from where two deep wadis intersect the course of the canal, Nahal Amud and Nahal Tzalmon . To overcome these obstacles, water is carried through inverted siphons. [1]
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.
King John V suggested substituting the piping to a fountain system (or inverted siphon system). [1] But, the municipal authority could only decide on reconstructing the arches, since the system was impractical in case of ruptures, requiring opening-up the entire network in case of localizing the problem.
The Rivervale Inverted Siphons, also known as the Rivervale Tunnel, are a historic flood control project in rural Poinsett County, Arkansas. It is essentially a very large concrete culvert , which channels the water flow of Ditch Number 4 under the Right Hand Chute Little River , into which it would normally drain.
