Sioux Chief 868-15WD 2" Water Dam for 15" Roof Drain, Plumbing Accessory

The Sioux Chief 868-15WD is a 2" water dam engineered specifically to pair with 15" roof drain assemblies on commercial and industrial flat-roof systems. Installed at the drain body, the water dam creates a raised barrier around the drain opening that helps retain a controlled depth of standing water for ponding roof designs or to manage overflow at the primary drain location. This is a behind-the-roof-membrane, rough-in accessory intended for use by licensed plumbers and roofing contractors during new construction or roof drain retrofit work, and it is manufactured by Sioux Chief for use with their 15" roof drain product line. The 868-15WD ships in a quantity of 5 EA per package, making it suited for contractors servicing multiple roof drain locations on a single job or stocking distributors supplying multi-unit commercial roofing projects.

Key Features

  • Trade Size: 2" water dam height designed to work with 15" roof drain assemblies.
  • Compatible Drain Size: Purpose-built to fit Sioux Chief 15" roof drain bodies for a correct, job-matched installation.
  • Water Retention Function: Forms a dam around the drain opening to maintain a defined water level for ponding roof or controlled-flow drainage applications.
  • Rough-In Roof Drain Accessory: Installs at the roof drain location as part of the overall roof drainage assembly, not a standalone fixture.
  • Multi-Pack Packaging: Supplied 5 EA per package for jobs requiring multiple roof drain locations.

Why Sioux Chief?

Sioux Chief manufactures a broad line of rough-in plumbing and roof drainage components designed to work together as matched systems, and the 868-15WD water dam is built specifically to pair with their 15" roof drain line for a correct fit on the job. Stocking this accessory alongside the matching roof drain helps contractors complete roof drainage installations with components engineered for compatibility rather than improvising a field fix. For plumbers and roofing contractors managing multiple drain locations, the 5 EA packaging keeps job-site inventory simple and reduces the need for separate reorders mid-project.

Sioux Chief 868-15WD – Frequently Asked Questions

1) Will the Sioux Chief 868-15WD water dam fit any 15 inch roof drain, or only Sioux Chief drains?
The 868-15WD is built to fit Sioux Chief 15 inch roof drain bodies. It is sized for that drain line specifically, so it should be ordered alongside a matching Sioux Chief 15 inch drain rather than fitted to another manufacturer's 15 inch drain body.
2) What does a 2 inch water dam actually do on a flat roof drain?
It forms a raised barrier around the drain opening so water backs up to a controlled depth before it drains. The 868-15WD stands 2 inches, which is the retained water level it establishes at the drain. That is what you want on a ponding roof design or where you are managing controlled-flow drainage at the primary drain location.
3) Is the water dam installed above or below the roof membrane?
Below. The 868-15WD is a behind-the-membrane rough-in accessory that installs at the drain body as part of the drainage assembly, so it goes in during new-construction rough-in or while the roof is opened up for a drain retrofit, not as a surface-mounted add-on afterward.
4) How many water dams come in a pack of the Sioux Chief 868-15WD?
Five each per package. If you are covering a roof with several drain locations, one package handles up to five drains, which is why it suits multi-drain commercial roofing work and distributor stock rather than a single replacement.
5) Can I buy the 868-15WD on its own, or do I need the roof drain too?
It is an accessory, not a standalone fixture. The water dam only functions as part of a roof drain assembly, so you need a Sioux Chief 15 inch roof drain body for it to mount to. Buyers replacing a damaged dam on an existing Sioux Chief 15 inch drain can order the dam by itself.
6) What part number should I put on a submittal for a 2 inch water dam on a 15 inch Sioux Chief roof drain?
Specify Sioux Chief 868-15WD. That is the full manufacturer part number for the 2 inch water dam matched to the 15 inch drain, and it is sold in packs of five.
