Sioux Chief 860-4PIW Fat Max Floor Drain Cast Iron Strainer

Product Description

The SIOUX CHIEF 860-4PIW is a large-capacity floor drain designed for high-flow drainage applications where debris capture and durability are priorities. It features a cast iron ring strainer combined with a stainless steel mesh debris basket, giving installers a two-stage system that handles both coarse material and finer particulate. The cast iron ring provides structural load resistance at the drain opening, while the stainless steel mesh basket intercepts debris before it enters the drain line. This unit is installed by licensed plumbers in commercial and residential settings where floor drainage must manage elevated flow volumes.

The 860-4PIW is suited for commercial kitchens, utility rooms, mechanical rooms, laundry areas, and similar spaces where floor drains are subject to grease, sediment, and debris-laden water. The large-capacity body supports higher flow rates than standard floor drains, making it appropriate for areas with frequent wash-down cycles or high-volume floor drainage demand. Its two-component strainer system simplifies routine maintenance by allowing the mesh basket to be removed and cleaned without disturbing the cast iron ring.

Key Features

• Large-capacity drain body supports high-flow drainage conditions
• Cast iron ring strainer provides durable, load-bearing surface at the drain opening
• Stainless steel mesh debris basket captures fine and coarse particulate
• Removable basket design allows fast cleanout without full drain disassembly
• Two-stage straining system reduces the risk of downstream line blockage

Compatibility

Designed as an OEM-style replacement or new-installation floor drain for commercial and residential plumbing systems requiring large-capacity drainage with integrated debris management.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local amendments. Shut off the water supply and ensure the floor area is dry and clear before setting the drain body. Verify rough-in dimensions and drain outlet size match the existing or planned rough-in before final installation. The debris basket should be inspected and cleaned regularly to maintain rated flow capacity.
