3/4" Brass Check Valve for Irrigation Systems, Lead Free

The last thing you want is for the water you're pumping out into your garden to get sucked back into the plumbing system of your house. This is called "backflow," and it's more common than it sounds! Luckily the solution to this is inexpensive and easy to use. A backflow preventer - sometimes called an anti-siphon device - will prevent this from happening. 

This item has 3/4" pipe threads, meaning it won't work with a garden hose or spigot without adapters. If you're looking for that, we'd suggest the A015 or A032. This item is best suited to applications that require high pressure, as its brass construction makes it much more resilient than its plastic counterparts.
