Top of the air scoop features a 1/8" NPT outlet and allows for connection of a regular air vent (such as Taco Hy-Vent part# 400-4). Bottom of the air scoop has a 1/2" NPT threaded outlet, which allows for connecting a plain steel diaphragm expansion tank.

Does this act as a back flow preventer or check valve
Read 1 answer
No. This air scoop only expands the line so that the water flow can slow down and the air bubbles can rise to the top of the scoop and be vented out through the automatic air vent, such as a Taco 400-4.
