A device that prevents backflow due to a siphoning action created by a partial vacuum that allows air into the piping system.
An anti-siphon device which prevents the backflow of non potable water into the water supply system. For example, if a handshower were left extended into a bathtub of dirty water, and a siphon effect were to occur, a vacuum breaker would prevent the tub water from traveling back into the water supply system.
An anti-siphon device that prevents waste water from being drawn back into supply lines, potentially contaminating the water supply. A type of backflow preventer.
An anti-siphon device that prevents the backflow of contaminated water into the water supply system in the event of a negative pressure condition.
A device that prevents back-siphoning of water into a water-supply line, usually in a faucet.
An anti-siphon device used to prevent the backflow of waste water into the water supply.
A small device used as an attachment to a handshower hose to prevent back siphoning of bath water – frequently, a plumbing code requirement. The Strom Plumbing Vacuum Breaker goes between the faucet body and handshower hose.
Also called a back-flow preventer, this device is placed on exterior faucets to allow water to only flow out of the home.
1. An electrical breaker with a space that contains rced air pressure. 2. A device which prevents the formation of a vacuum in a water supply pipe; installed to prevent backflow.
A safety device to prevent the back flow of non potable water back through the faucet and into the potable water system. Back flow conditions occur when the potable water system is less than atmospheric pressure. Contamination conditions occur when the faucet outlet is submerged in contaminated water at atmospheric pressure or a positive back pressure and there is a unobstructed delivery of contaminated water into the potable water system. The vacuum breaker has an atmospheric port, which admits atmospheric air into the outlet to prevent back siphonage should the check valve in the vacuum breaker become fouled with line trash.
Device to prevent the formation of a vacuum, used primarily to prevent back siphonage.
A mechanical device which automatically vents a water line to the atmosphere when subject to a partial vacuum, thus preventing back siphonage.
A device to prevent backflow (back siphonage) by means of an opening through which air may be drawn to relieve negative pressure (vacuum).
An attachment commonly placed on a bibcock valve, that prevents water from being sucked backward from a garden hose into the public water system. This prevents contamination should the public water system's pressure drop.
