This wiki has been updated 10 times since it was first published in October of 2018. There are two types of water in this world: the clear stuff that's delicious and safe to drink, and the other kind. With these backflow preventers, you won't have to worry about the latter mixing in with the good H20 in your home or RV, as they ensure that the water in the line only goes in one direction. We've included options suitable for both large and small installations. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki.

Editor's Notes

January 10, 2019:

There's a wide disparity in price points between some of the options on this list. That's due to the fact that certain models, like the Plumb Craft Waxman 7032000N, are ideal for things like garden hoses, while you'll need a larger and more formidable model for wide-scale irrigation and home use. We strove to cover all of our bases in terms of applications, which naturally led to diverse costs.

After getting his bachelor’s from the University of Texas, Quincy Miller moved out to Los Angeles, where he soon found work as a copywriter and researcher, specializing in health and wellness topics for a major online media brand. Quincy is also knowledgeable about home improvement, as he’s had extensive experience with everything from insulation to power tools to emergency room trips, sometimes in that order. Sharing a home with three dogs and a couple of cats has forced Quincy to learn as much as he can about pet supplies, animal nutrition and, most importantly, the best ways to tackle the mountains of fur that accumulate in every corner of your home.
