Sioux Chief 868-D524W Combination Roof Drain with Overflow, Cast Iron, 4" No-Hub

The Sioux Chief 868-D524W is a cast iron combination roof drain with integral overflow, engineered for commercial rough-in roof drainage applications where a primary drain and a secondary overflow path are required at the same roof penetration. Built with a 4" no-hub connection for a secure fit to cast iron DWV piping, this combo drain assembly is designed for the demanding, behind-the-wall and below-deck conditions typical of commercial roof drainage systems. The cast iron body provides the strength and durability that roofing contractors and plumbers expect from a long-service drainage fitting installed in a roof deck.

Key Features

  • Trade Size: 4" connection sized for standard commercial roof drain piping runs.
  • Durable Construction: Cast iron body resists the long-term wear associated with roof drainage service.
  • No-Hub Connection: 4" no-hub outlet allows a straightforward mechanical joint to cast iron no-hub drainage pipe using standard no-hub couplings.
  • Combination Design: Integrated overflow function paired with the primary drain body in a single roof penetration, reducing the number of separate roof fittings a crew has to install and flash.
  • Single-Unit Packaging: Supplied 1 EA for straightforward ordering per drain location.

Why Sioux Chief?

Sioux Chief builds rough-in drainage products around materials and connection types that plumbing and roofing contractors rely on for commercial-grade performance, and this combination roof drain is no exception, pairing a cast iron body with a 4" no-hub connection sized for standard cast iron DWV systems. Choosing a combo roof drain with overflow in a single cast iron assembly helps streamline the roof penetration count on a project while giving the trade a connection type they already know how to join in the field.

Sioux Chief 868-D524W – Frequently Asked Questions

1) Does the Sioux Chief 868-D524W roof drain handle both the primary and the overflow drain in one roof penetration?
Yes. The 868-D524W is a combination roof drain with an integral overflow, so the primary drainage path and the secondary (overflow) path are handled in the same cast iron body at one penetration. That cuts the number of separate fittings a crew has to set and flash compared with running a stand-alone primary drain plus a separate overflow drain. Note that a combo drain still requires separate piping for the overflow leg downstream.
2) Is a cast iron combination roof drain the right choice for a flat or low-slope commercial roof?
That is exactly the service this drain is built for. The 868-D524W is intended for commercial roof drainage on low-slope and flat roof decks, both in new construction and in roof retrofit rough-in. The cast iron body is the usual pick where the drain has to take long-term abuse in the deck, versus lighter plastic or aluminum bodies used on residential or lighter-duty work.
3) Can I use a no-hub roof drain with PVC or ABS drainage pipe?
A no-hub outlet is a plain spigot joined with a shielded no-hub coupling, and the 868-D524W is specified for cast iron no-hub DWV piping. Plastic DWV lines are normally transitioned with the appropriate coupling rather than joined directly, so if the system below the deck is PVC or ABS, plan the transition at the drain outlet or specify a drain with the matching outlet type.
4) How many drains do I get when I order the Sioux Chief 868-D524W?
One. It ships 1 EA, so you order per drain location. On a roof laid out with a primary and overflow pair at each sump, a combination unit like this covers both functions at that one location rather than needing two units.
5) What is the manufacturer part number to order this Sioux Chief combo roof drain with overflow?
Order it as Sioux Chief 868-D524W. That number covers the cast iron combination roof drain with overflow in the 4 inch no-hub configuration, which is the only size this model is built in.
