Description

NSF CERTIFIED — QUALIFY FOR HOME INSURANCE DISCOUNTS: This valve meets NSF standards recognized by major U.S. insurers. Installing a qualified smart shutoff valve may reduce your annual home insurance premium by 5–10%. Keep your certification documentation and contact your insurer after installation to claim your discount.

3-IN-1 ULTRASONIC DETECTION — PRESSURE, TEMPERATURE & FLOW: Unlike basic flow-only valves, our W-type ultrasonic sensor simultaneously monitors water pressure, temperature, and flow rate. Abnormal pressure signals a burst pipe. A sudden temperature drop warns of freezing. Unusual flow catches hidden leaks — all before a $11,000+ water damage claim happens.

AUTOMATIC SHUTOFF + REAL-TIME APP ALERTS, ANYWHERE: Connects directly to 2.4GHz and 5GHz WiFi — no hub or gateway required. Receive instant alerts via the Smart Life app when abnormal flow is detected, and shut off your main water line remotely in seconds. Set custom automation scenes with compatible Haozee leak sensors (sold separately) for fully hands-free protection.

SMART WATER METER — TRACK DAILY & MONTHLY USAGE: Monitor real-time consumption, daily totals, and monthly history directly in the app. Set custom flow thresholds: automatically shut off if usage exceeds your limit (e.g., 100 gallons in a single session or 1,000 gallons per day). Ideal for vacation homes, rental properties, and households wanting to reduce water waste and utility bills.

EASY DIY INSTALLATION — IP66 WATERPROOF, FCC CERTIFIED: Fits standard 3/4 inch (DN20) main water line pipes. Complete installation in 15–20 minutes with included fittings — no plumber required. NSF & FCC dual certified. IP66 rated for reliable indoor and covered outdoor use. Note: This model requires continuous power (no built-in battery). For battery backup functionality, see our Haozee HZ-WV-01 model.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $22 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Haozee products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
