Johnson Pump Vented Loops are used to prevent back siphoning and are used in toilet discharge lines or in systems mounted below the water line. The inverted U-shape has a vent on the top allowing air to escape and breaking any siphoning. The vented loop should be installed above the heeled waterline. Available in three sizes.
