Review on 🚰 Sioux Chief 696 1021GF Box Outlet: Superior Performance and Enhanced Convenience for All Plumbing Needs by Elvis Bragg

Sioux Chief makes different models for different pipe applications, but Revain states that this vent box is universal. This model is designed for iron pipe and needs csst female adapter if you use csst. See my review of the 3/4 inch model for more information and photos of the actual box contents. I had the same issues with both sizes.
