Abstract:
1. A kit for assembling a de-aerator for removing gas from a liquid distribution system comprising: a T-coupling for installation in a run of pipe in the liquid distribution system, the T-coupling providing a chamber defined by a cylindrical wall that is axially aligned with a cap connector and a pipe connector of the T-coupling, the cylindrical wall being interrupted only by one cylindrical opening passing transversely through the cylindrical wall, the cylindrical opening being defined by a second pipe connector and the chamber providing an unobstructed fluid path through the T-coupling; a cap having a mating surface for sealed connection to the cap connector; a valve in fluid communication with the chamber, and a valve stem connected to a float for selectively opening the valve only when the liquid in the chamber is displaced by the gas below a predetermined level; and a gas concentrator for extracting gas from the liquid flowing through the chamber, the gas concentrator retained within the chamber below the valve to ensure that extracted gas rises into a space below the valve.
