About This Product

If you've ever worried about dirty water backing up into your home's supply from a garden hose, this PK1400 vacuum breaker gives you peace of mind.
It's a self-draining anti-siphon valve that attaches to your 3/4-inch hose thread.
The main job?

Preventing backflow – so contaminated water from your hose doesn't get sucked back into your clean water lines.
But it's also smart about freezing: when you shut off the water, it automatically drains, which helps prevent burst pipes in cold weather.

Perfect for use on frost-proof wall hydrants, hose bibbs, or ground yard hydrants.
Made from lead-free brass, so it's safe and durable, with excellent corrosion resistance.
The inlet is 3/4-inch FHT and the outlet is 3/4-inch MHT, and it handles up to 125 PSI and 180°F.

Installation is super simple – no complex tools needed.
It even comes with a breakaway set screw for permanent setups.
If you're not completely happy, there's a 30-day return policy and a 12-month warranty.
