Bd Manufacturing SK644K04 Heat Pump Parallel Header

Product Description

The BD MANUFACTURING SK644K04 is a parallel underground header designed for heat pump loop field piping. It features a 1-1/4 inch socket inlet and five 3/4 inch socket outlets, allowing a single supply or return main to branch into multiple ground loop circuits in one fitting. The socket-by-socket configuration supports solvent-welded HDPE or PVC connections, which is the standard joining method for geothermal loop systems. This fitting is installed by geothermal HVAC contractors and plumbers during the underground loop field portion of a heat pump installation.

This parallel header is used in residential and light commercial geothermal heat pump systems where multiple ground loops must be combined into a single header. The 1-1/4 inch main port handles the combined flow from up to five 3/4 inch branch circuits. It is suited for horizontal, vertical, or pond loop configurations where underground header manifolds are required to balance and consolidate loop piping before entering the building.

Key Features

• 1-1/4 inch socket inlet connects to main supply or return header piping
• Five 3/4 inch socket outlets for multi-circuit ground loop branching
• Parallel flow design balances flow across all loop circuits
• Socket-by-socket construction supports solvent-welded field connections
• Designed for underground installation in heat pump loop fields

Compatibility

Designed as an OEM-style fitting for geothermal heat pump loop field piping systems using 1-1/4 inch main headers and 3/4 inch branch loop circuits.

Installation Notes

Installation is typically performed by a licensed geothermal or plumbing contractor following local mechanical and plumbing codes. All socket connections should be made using the appropriate solvent cement rated for the pipe material being used. Ensure all joints are fully cured before backfilling the trench or boring. Pressure-test the completed loop field assembly before connecting to the heat pump unit.
