Sioux Chief 887-PM Pvc Closet Flange 4x3 in Sch 40

Product Description

The Sioux Chief 887-PM is a 4-inch by 3-inch Schedule 40 DWV open PVC closet flange designed for connecting a toilet to the drain-waste-vent system in residential and light commercial plumbing installations. This flange features an open-bottom design that allows insertion into a 3-inch DWV pipe while the 4-inch top ring seats flush against the finished floor surface. The Schedule 40 PVC construction provides reliable durability for standard drain line service. Licensed plumbers and experienced rough-in crews install this flange during new construction or remodel work where toilet rough-in and floor connections must meet code.

This closet flange is suited for residential toilet installations and light commercial bathroom applications where a 3-inch DWV drain line is present beneath a finished floor. The open-bottom configuration allows the flange to drop into the existing riser pipe, making it a practical choice during new construction rough-in as well as retrofit projects. It is sold in a package quantity of 25 units, making it well suited for contractors and plumbing supply houses handling multi-unit residential or commercial projects.

Compatibility

Designed as an OEM-style replacement and new-construction fitting for residential and light commercial toilet drain connections using 3-inch Schedule 40 DWV PVC pipe.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and ensure the drain line is clear before securing the flange. Solvent-weld the flange to the 3-inch riser pipe using PVC primer and cement rated for DWV applications. Do not over-torque the closet bolts when setting the toilet, as this can crack the flange ring.
