### ⭐⭐⭐⭐⭐ It worked beautifully
*by D***Y on July 24, 2022*

My contractor installed a plastic check valve, which failed after about 3 months of use. Ordered this one but installed another plastic one while I waited for it to arrive. It arrived and the new plastic valve failed... weird. But installed the brass one and it is working great.
