Sioux Chief Mfg Co. 883-PT Flush Closet Flange 3x4 Inches

Product Description

The SIOUX CHIEF MFG CO. 883-PT is a flush-to-floor PVC closet flange designed for toilet drain connections in residential and light commercial plumbing installations. It features a total knockout configuration, allowing the installer to remove the knockout ring as needed to suit the specific drain pipe condition. Sized for a 3-inch inside by 4-inch outside drain connection, this flange sits flush at the finished floor surface, making it suitable for installations where a raised flange is not appropriate. Licensed plumbers and plumbing contractors are the primary installers of this fitting.

This flange is used in residential and light commercial bathroom rough-in work where the drain line terminates at or just below the finished floor level. The flush design eliminates the need to cut down a raised flange on low-profile installations. The total knockout feature provides flexibility during installation, allowing the drain pipe to remain capped until the toilet is set. It is appropriate for new construction as well as remodel applications where finished floor height is a consideration.

Key Features

• Flush-to-floor design suits installations where raised flanges are not appropriate
• Total knockout ring provides flexibility — remove only when needed for drain connection
• 3-inch inside by 4-inch outside PVC construction for standard residential drain sizing
• PVC material resists corrosion and chemical attack from drain environments
• Package quantity of 25 units per case supports contractor volume needs

Compatibility

Designed as an OEM-style replacement and new-installation fitting for standard 3-inch inside by 4-inch outside PVC toilet drain rough-ins in residential and light commercial plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and ensure the drain line is clear before setting the flange. Secure the flange to the subfloor using appropriate fasteners and verify the flange sits flush with the finished floor surface before setting the toilet. Do not overtighten closet bolts during toilet installation, as this can crack the flange ring.
