Sioux Chief 868-1503 Roof Drain with Cast Iron Dome, 15" Diameter, 3" NH

The Sioux Chief 868-1503 is a 15" diameter roof drain assembly featuring a cast iron dome strainer and a 3" no-hub (NH) outlet connection, built for commercial and residential roof drainage rough-in work. Installed at the low point of a flat or low-slope roof deck, this drain is designed to channel stormwater into the building's drain-waste-vent (DWV) piping system while the cast iron dome keeps debris, leaves, and larger material out of the line. The 3" NH outlet is sized to mate directly with standard no-hub cast iron or compatible DWV piping using a no-hub coupling, making it a straightforward tie-in for plumbers working the drainage rough-in on new construction or re-roofing projects. As with all rough-in drainage components, this unit is intended to be installed behind the finished roof surface and tied into the building's drain piping by a qualified plumbing contractor.

Key Features

  • Trade Size: 15" diameter drain body for roof deck installations requiring a wide debris-catching dome.
  • Durable Construction: Cast iron dome strainer provides a rigid, heavy-duty cover that resists impact and weathering while keeping large debris out of the drain line.
  • Connection: 3" NH (no-hub) outlet for a direct, gasketed tie-in to no-hub cast iron or compatible DWV piping using a standard no-hub coupling.
  • Dome Strainer Design: The raised cast iron dome configuration allows continued water flow into the drain even if leaves or debris begin to accumulate around the base.
  • Rough-In Ready: Supplied as a single roof drain assembly (1 EA packaging) ready for set-in and connection during the drainage rough-in phase.

Sioux Chief 868-1503 – Frequently Asked Questions

1) Will the Sioux Chief 868-1503 roof drain tie into 3 inch no-hub cast iron DWV piping?
Yes. The 868-1503 has a 3 inch no-hub outlet, so it mates directly to no-hub cast iron or compatible DWV pipe with a standard no-hub coupling and gasket. No adapter or threaded fitting is needed, and nothing is caulked or hubbed.
2) What size roof opening does the 15 inch Sioux Chief 868-1503 drain cover?
The drain body and cast iron dome are sized for a 15 inch diameter drain opening, so plan the deck cut and membrane flashing around that 15 inch footprint. That is the trade size stated for the assembly.
3) Cast iron dome or plastic dome for a commercial flat roof drain?
Go cast iron where the dome can take foot traffic, hail, or dropped tools, which is the usual case on a commercial flat roof with rooftop equipment and service access. The 868-1503 uses a cast iron dome strainer, a rigid heavy cover that resists impact and weathering. Plastic domes are lighter and cheaper but crack under impact, so they suit low-traffic residential work better.
4) Does the dome keep the roof drain flowing when leaves pile up?
That is the point of the raised dome. Water enters through the sides of the cast iron dome above deck level, so flow continues even as leaves and debris collect around the base. A flat strainer blinds off much faster. It still needs seasonal clearing on a leafy site.
5) Is the Sioux Chief 868-1503 one complete drain or do I order the dome separately?
It ships as a single complete roof drain assembly, one each, dome included, ready to set in and connect during drainage rough-in. You will still need the no-hub coupling for the 3 inch outlet tie-in and whatever flashing or clamping the roof membrane detail calls for.
6) Can this roof drain be used on a residential re-roof, or is it commercial only?
Both. The 868-1503 is built for flat and low-slope roof drainage on commercial and residential work, new construction or re-roofing. It sets at the low point of the deck behind the finished roof surface and ties into the building storm or DWV piping, so it is a plumber's rough-in item rather than a surface-mounted retrofit.
