Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Sioux Chief 2 in. D Polypropylene Backwater Device protects your home from sewer backups with a compact, reliable solution designed for residential drainage. Crafted from lead-free polypropylene, this backwater device combines safety, durability, and easy installation for lasting performance in everyday plumbing scenarios.

  • Size and material: 2" diameter body (D) with a 3" length, manufactured from durable, chemical-resistant polypropylene.
  • Connection type: Screw-in connection for straightforward, secure installation into compatible 2" drain lines.
  • Safety and cleanliness: Lead-free construction ensures safe, dependable operation in wastewater environments.
  • Packaging: Bagged packaging protects the unit during handling and storage until installation.
  • Application: Backwater device designed to prevent backflow and sewer surges from entering the building through drainage systems.

What makes this Sioux Chief backwater device stand out is its combination of a simple, screw-in installation with a robust polypropylene body that resists corrosion and chemical exposure. The result is a compact, low-maintenance solution that fits tight spaces while providing dependable backflow protection when municipal sewers surge.

Ideal use cases

  • Basement floor drains that need protection during heavy rainfall or sewer backups.
  • Laundry room drains where backflow can contaminate clothes and appliances.
  • Crawl spaces or utility areas where space is limited but backflow prevention is essential.

Practical tips

  • Confirm compatibility: designed for 2" drain lines with a screw-in interface. Verify your piping matches this specification before purchasing.
  • Plan maintenance: inspect the device periodically for any signs of cracking or leakage to ensure continued protection.
  • Code compliance: consult local plumbing codes and, if unsure, work with a licensed plumber to ensure proper installation and compliance.
