Webstone H-81413KIT Pump Installation Kit 3/4 in Press Flange

Product Description

The WEBSTONE H-81413KIT is a pump installation kit designed for hydronic heating and cooling systems. It includes isolator valves with a rotating flange configuration, allowing technicians to remove and service inline circulators without draining the system. The 3/4 inch press connection on one side simplifies joining to copper pipe, while the rotating flange side mates directly to standard circulator pump flanges. This kit is suited for licensed plumbers and HVAC mechanics working on closed-loop hydronic systems in residential and light commercial applications.

This kit is intended for use in hydronic pump installation and service scenarios where isolation of the circulator is required. The press-by-rotating-flange configuration makes it well suited for new construction and retrofit installations where fast, reliable connections to copper piping are needed. It is commonly installed on boiler loops, radiant heating systems, and chilled water fan coil circuits where routine pump service must be performed without full system drain-down.

Key Features

• 3/4 inch press connection for tool-based joining to copper pipe without open flame
• Rotating flange allows proper alignment to circulator pump bolt pattern during installation
• Isolator valve design enables pump removal and replacement without draining the system
• Kit format provides matched components for a complete pump isolation installation

Compatibility

Designed as an OEM-style replacement and new-installation kit for standard residential and light commercial hydronic circulator pumps using 3/4 inch press connections and rotating flange interfaces.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC mechanic familiar with hydronic system service. Shut down the boiler or chiller and relieve system pressure before beginning work. Press fittings require a rated press tool and the correct jaw size for the pipe diameter. Verify the rotating flange gasket is seated properly and bolts are tightened evenly before returning the system to service.
