They’re heavy and sturdy they look good. They came with Teflon tape and two extra washers. The permanent attachment screw is nice.

### ⭐⭐⭐⭐⭐ Code Compliant Backflow Preventer
*by D***N on June 11, 2026*

the product arrived quickly and was exactly as described.

### ⭐⭐⭐⭐ Not for low flow systems
*by G***. on August 27, 2025*

These seem fine, but when used in a low pressure drip irrigation system they create an intolerably loud whine that resonates on every water pipe in the house. Ultimately I ended up returning and going with a plastic rainbird product that did not whine.
