About Us

Our Purpose: Protect the Safety of Your Water

We started in 2012 as a small team designing and manufacturing a backflow prevention line that would later be called the Deringer. Today, the Deringer product line is known as the smallest, lightest, and only all stainless steel backflow prevention valve on the market – and they’re built right here in the USA.

Over the years, we’ve continued to design shorter, lighter, and better performing products that you can rely on. That’s why our backflow preventers and every other product we carry are all safety certified, so you can rest assured knowing you have a reliable, high-quality product.

✓ All of our Products Have Been Fully Certified (UL, FM, ASSE, CSA, NSF, USC) in Backflow Prevention
✓ Six issued U.S. Patents in Backflow Prevention
✓ Three U.S. Patents Pending in Backflow Prevention
