In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

Every order helps keep your local hardware store on the corner.

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 Rubber Backup Float Valve is a rugged, secondary shut-off designed to protect water systems from overflow and unintended drainage. Crafted from durable rubber, this valve stands up to everyday use in residential and light commercial settings, with a respectable operating range that keeps your system in check.

Why choose this backup float valve?

  • 2 in. inlet and 2 in. outlet connections provide straightforward integration with standard piping and float valve assemblies.
  • Rubber construction offers reliable performance in moist environments while resisting wear, corrosion, and mineral buildup over time.
  • Bagged packaging ensures a clean, ready-to-install part straight from the box.
  • Built-in protection adds a critical layer of safety to prevent overflows when the primary valve is momentarily compromised or during pressure surges.
  • Thermal and pressure tolerance supports typical residential use, with a maximum pressure of 50 psi and a maximum temperature of 180°F, helping to safeguard against common system variations.

Ideal for:

  • Residential and light commercial water systems that rely on 2" connections and want extra overflow protection.
  • Mechanical rooms, equipment cabinets, and 2" line installations where a compact backup valve adds reliability without bulky components.
  • Maintenance and retrofit projects where a dependable, easy-to-replace rubber backup valve can extend the life of existing plumbing assemblies.

Practical guidance for use:

  • Confirm compatibility with your current 2" piping and float valve setup before installation.
  • Operate within the rated 50 psi and 180°F to maximize lifespan and performance.
  • Keep the valve clean and protect it from prolonged exposure to extreme conditions outside its specifications.

With Sioux Chief’s trusted design and a purpose-built rubber body, this 2 in. backup float valve delivers dependable overflow protection where it matters most—so your water system remains safe, efficient, and leak-free.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
