The IPEX 40766 is a PVC offset downspout adapter manufactured to SDR35 standards, designed to transition roof drainage from a downspout into a buried drain line. This fitting accommodates offset connections where the downspout outlet and the underground pipe inlet are not perfectly aligned, allowing installers to make the transition without additional fittings. The SDR35 wall thickness rating makes it suitable for standard gravity-flow storm drainage applications. Plumbers and drainage contractors working on residential and light commercial stormwater systems will find this adapter useful during rough-in and site drainage work.
This adapter is used in exterior stormwater and drainage installations where a roof downspout must connect to an underground SDR35 PVC drain line. The offset geometry accommodates typical site conditions where the downspout position does not fall directly over the buried pipe centerline. It is appropriate for residential and light commercial applications involving gutters, leaders, and underground storm drain systems installed per local plumbing and site drainage codes.
Designed as an OEM-style replacement or new-installation fitting for SDR35 PVC gravity-flow storm drainage and downspout drain systems.
Installation should be performed by a licensed plumber or drainage contractor in accordance with local plumbing and site drainage codes. Ensure all upstream downspout and gutter connections are secure and that the underground drain line is properly bedded before making the final connection. Solvent-weld all PVC joints per the fitting manufacturer recommendations and allow adequate cure time before backfilling. Do not use this fitting for pressurized piping systems.
