Sioux Chief 869-S58 Backwater Valve & Sleeve Kit, PVC

The Sioux Chief 869-S58 is a PVC backwater valve and sleeve kit from the 869S Series, built for horizontal, gravity-flow drain-waste-vent lines where backflow protection is required. This kit is available in 3" and 4" Schedule 40 DWV sizes, so installers can match the valve to the pipe diameter on site while relying on the same engineered design across both sizes. Molded from tough, engineered resins, the valve body is structurally rugged enough to handle the stresses of in-ground DWV installation, and the included sleeve lets installers adapt the assembly for either shallow-bury or deep-bury placement depending on job-site conditions.

Key Features

  • Trade Size Range: Offered in 3" and 4" sizes for Schedule 40 DWV drain lines, covering common residential and light commercial drain diameters.
  • Durable Construction: Molded from tough, engineered resins for structural strength in buried horizontal drain applications.
  • Sleeve Kit Included: Adjustable sleeve allows the valve to be set up for shallow-bury or deep-bury installation, giving installers flexibility for varying trench depths.
  • Modular Valve Design: Accepts interchangeable accessories across both the 3" and 4" configurations, simplifying service and future reconfiguration.
  • Horizontal, Gravity-Flow Use: Engineered specifically for horizontal, gravity-flow installations rather than vertical or pressurized runs.
  • PVC Material: Compatible with PVC DWV piping systems common in residential and light commercial rough-in work.

Technical Specifications

  • Country of Origin: United States
  • Packaging: 1 EA
  • Available Sizes: 3" and 4" Schedule 40 DWV

Typical Applications

  • Residential and Commercial Rough-In Drain-Waste-Vent Lines
  • Horizontal Gravity-Flow Backwater Protection

  • New Construction and Below-Grade DWV Rough-In
  • Sump and Basement Drain Backflow Prevention

Why Sioux Chief?

Sioux Chief engineers its 869S Series backwater valves from tough, engineered resins and a modular design that gives plumbers and contractors flexibility on the job site, from accessory interchangeability across the 3" and 4" sizes to adjustable bury depth via the included sleeve kit. Manufactured in the United States, the 869-S58 kit is built for the rigors of buried, horizontal DWV installations where a reliable gravity-flow backwater valve is required, helping protect below-grade drain lines from backflow in both new construction and renovation rough-in work.

Sioux Chief 869-S3PS – Frequently Asked Questions

1) Can I use a Sioux Chief 869S backwater valve on a vertical drain stack or a pressurized line?
No. The 869S Series backwater valve is built for horizontal, gravity-flow drain-waste-vent lines only. It is not intended for vertical runs or pressurized piping. If your run is vertical or under pressure, this is the wrong device for the opening.
2) My sewer line is buried deep. Do I need a separate riser for the 869-S58 kit?
The kit ships with an adjustable sleeve that sets the assembly up for either shallow-bury or deep-bury placement, so trench depth is handled within the kit itself rather than with a separate riser purchase.
3) Will this backwater valve glue into my existing PVC DWV piping?
Yes. The valve body is PVC and is made to work with PVC DWV piping systems in 3 inch or 4 inch Schedule 40. If your below-grade drain line is cast iron or another material, you would need an appropriate transition coupling to get to PVC of the matching diameter.
4) If I stock both 3 inch and 4 inch 869S valves, do I need two sets of service parts?
No. The 869S valve uses a modular design that accepts interchangeable accessories across both the 3 inch and 4 inch configurations, so a property manager or MRO buyer standardizing on the series can carry one accessory set for both diameters.
5) What is the 869-S58 kit actually for on a basement drain job?
It is a backwater valve, a one-way device set into a horizontal below-grade drain line to keep sewage from backing up into the building when the municipal line surcharges. Typical uses are residential and light commercial DWV rough-in, below-grade sewer runs, and sump or basement drain backflow protection in both new construction and renovation.
6) Is the Sioux Chief 869S backwater valve made in the USA?
Yes, the 869S Series backwater valve and sleeve kit is manufactured in the United States, which matters on public and institutional work with domestic-sourcing requirements.
7) How is the 869-S58 backwater valve packaged, each or by the case?
It is sold as a single kit, packaged 1 each, with the valve and sleeve together.
