BackflowDirect.com Reviews
About this CompanyWe 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

Why Trust Verified Reviews?
Verified Reviews are real, authentic reviews collected from actual paying customers, using Shopper Approved's Verified Review Platform. When reviews are Verified by Shopper Approved, you know that you can trust them to make better buying decisions.
Unverified Reviews on the other hand, are reviews collected by Open Review platforms that allow anyone to leave a review, without any validation or proof of purchase. Unfortunately, most reviews you read online are Unverified Reviews, and can't be trusted.
As a consumer, here's how you can tell the difference:
Verified Reviews from Verified Review Platforms like Shopper Approved, have much higher review counts and higher overall Star ratings, because they attempt to collect reviews from every single paying customer.
Unverified Reviews from Open Review Platforms, tend to have much lower review counts and more negative Star ratings, because people with bad experiences are primarily those who leave reviews. This often creates a misleading, inaccurate portrayal of a companies true reputation.
So, when searching for Verified Reviews, look for the name you know you can trust. Shopper Approved.
