摘要：A near-boiler piping loop apparatus is provided including a primary/condary piping loop interface apparatus having a unitary construction including a condary loop shut-off valve, drain valve and drain port in each branch of a condary loop for connection to a boiler. Supply branch piping and return branch piping connects the
interface apparatus to the boiler and provides attachment points for auxiliary plumbing equipment. The apparatus is adapted to connect to pump in variable orientations using rotatable flanges on the interface apparatus and on a wye strainer in the condary loop supply branch and includes a union fitting attached to the interface apparatus. The union fitting provides a mounting hole for a temperature or pressure gauge.
