The AIR FLOW PRODUCTS PI04PR26GA is a 4-inch conductor pipe fabricated from 26-gauge sheet metal. Conductor pipe is used in rooftop drainage systems to channel water from roof drains down through the building structure. This product is a straight pipe section designed for use in vertical or near-vertical drainage runs. Licensed plumbers and sheet metal contractors typically handle the selection and installation of conductor pipe in commercial and residential applications. The 26-gauge construction provides a balance of rigidity and workability suited to standard drainage rough-in work.
This conductor pipe section is suited for rooftop and interior drainage applications where a 4-inch diameter pipe is specified. It fits into standard conductor pipe systems used in flat or low-slope commercial roofing configurations, as well as in some residential downspout and scupper drain assemblies. It is commonly used alongside roof drains, elbows, and couplings to complete a vertical drainage stack.
Designed as an OEM-style replacement or new-installation component for standard 4-inch conductor pipe drainage systems in commercial and residential rooftop drain assemblies.
Installation should be performed by a licensed plumber or qualified sheet metal contractor in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off or isolate the drainage system and ensure the roof drain is cleared before beginning pipe replacement or new installation. Use appropriate sheet metal joining methods and sealants as required by the project specifications. Do not overtighten mechanical couplings, as this can deform the pipe wall on lighter-gauge material.
