- 39. A water distribution pipe that routes a water supply vertically one full story or more.
- 40. A vacuum pump that ejects air from the suction line of a larger suction-lift pump installation.
- 41. The process in which microscopic gas bubbles expand in a vacuum and suddenly implode when entering a pressurized area.
- 43. A system of pipes, fittings, and fixtures within a building that conveys a water supply and removes wastewater and waterborne waste.
- 46. A device used to connect two lengths of pipe.
- 47. A sewer used for conveying groundwater, rainwater, surface water, or similar nonpolluting wastes.
- 49. The difference in water pressure between points at different elevations.
- 50. The process of overcoming suction lift and getting liquid to a pump inlet.
- 51. The part of a drainage system that connects the building drain to the sanitary sewer.
- 52. A sewer that carries sewage but does not convey rainwater, surface water, groundwater, and similar nonpolluting wastes.
- 53. A pump with a rotating impeller that uses centrifugal force to move water.
Down
- 1. A valve that permits fluid flow in only one direction and closes automatically to prevent backflow (flow in a reverse direction).
- 2. A check valve with a hinged disk.
- 3. The volume of water passing a point at a particular moment.
- 7. A check valve installed at the bottom of the suction line on a suction-lift pump that keeps the suction line primed when the pump shuts down.
