About this detail

A mechanical piping riser configuration with supply and return lines, air flow ducts, and inline components including a mixing type modulating control valve with spring return, a Y-strainer with a three-quarter-inch hose end drain valve, isolation butterfly valves, and circuit balancing valves with memory stops. A manual air vent is provided at high points above ceilings where required, routed with half-inch Pete's plugs and a drain line to the floor drain. The riser foot support consists of a one-and-a-half-inch pipe capped at the top, a one-inch nut welded inside the pipe, a one-by-four-inch anchor threaded rod welded to a four-by-four-by-one-eighth-inch plate, and a half-inch waffle pad resting underneath the base plate.
