Spray Cannon is a simple snap-together attachment that redirects the messy backflow spray from vacuum breakers into a clean, controlled stream — so you stay dry and can capture reusable water.

If your garden hose shoots water from the spigot area every time you shut it off, you're experiencing backflow from your vacuum breaker — a small device required by modern plumbing codes (IPC, UPC, and most local building codes) on outdoor hose bibs. Vacuum breakers prevent contaminated water from being siphoned back into your home's clean water supply, which is essential for health and safety. However, the trade-off is that residual water trapped between the vacuum breaker and the hose nozzle gets expelled as an uncontrollable spray when pressure drops. This isn't a defect or broken spigot — it's working exactly as designed. Spray Cannon solves the annoying side effect without removing or tampering with the required safety device.

Installation is incredibly simple and takes less than 60 seconds. No tools required, no threading, no plumber needed, and no modifications to your plumbing.

1. Disconnect the hose from the spigot.
2. Separate Spray Cannon's two pieces — the Top Part and the Barrel.
3. Slide the Top Part over the vacuum breaker on the spigot.
4. Slide the Barrel onto the hose end.
5. Attach the hose end to the vacuum breaker.
6. Position the Top Part over the vacuum breaker and snap it together with the Barrel.
7. Snug the thumb screw to secure.
8. Place a container under Spray Cannon to capture spray for re-use.
