SUNGATOR 12-Pack Anti Siphon Valve 3/4 in GHT Backflow Preventer

In this review of the SUNGATOR 12-Pack Anti Siphon Valve kit, the bottom line is simple: this bulk set is aimed at homeowners, gardeners and RV owners who need multiple reliable backflow preventers for outdoor faucets. The biggest reason to buy is the combination of heavy-duty brass construction and a 12-piece quantity that covers several spigots or seasonal replacements at once. The review will look at build quality, installation, and real-world performance so you can decide if a multi-pack anti-siphon solution fits your plumbing needs.

Key Features

• 12-piece supply: The package includes twelve 3/4 in GHT anti-siphon valves, making it easy to outfit multiple outdoor faucets without repeated purchases.
• Durable brass body: Each valve is crafted from heavy-duty brass to resist corrosion and extend service life in outdoor conditions.
• Integrated drain hole: The vacuum breaker has a drain hole that releases remaining water when pressure changes, helping to prevent freezing and siphoning.
• Permanent attachment option: A break-off screw allows for a permanent, tamper-resistant installation on standard hose bibs.
• Installation kit included: The set supplies twelve washers and a roll of sealing tape so buyers can install multiple valves right away.
• Plumbing compatibility: Designed with a 3/4 in female GHT inlet and 3/4 in male outlet to fit standard garden hoses, RV connections and sillcocks.

Who It's For

This kit is best for homeowners with several outdoor faucets, property managers, landscapers, or RV owners who want to standardize backflow protection across multiple points. It is especially useful if you use collapsible hoses or swap hoses between water sources, since customers report reliable performance with those hose types.

Those who should look elsewhere include people with fine-thread fittings or nonstandard plumbing, because the valves are not intended for fine threads. Also, if you need a single valve for occasional use, a 12-pack may be overkill and a single or three-pack option would be more economical.

Pros & Cons

Pros

• Solid brass construction delivers corrosion resistance and a sturdy feel in the hand.
• Comes with washers and a long roll of sealing tape, so installations are ready out of the box.
• Bulk quantity provides clear value for multi-faucet properties or seasonal replacements.

Cons

• Some users report occasional water spray from the drain hole when shutoff occurs, so care is needed during operation.
