Review on 🔧 Improved Sump Check Valve by Jackel (Model: DJ-545) by Christopher Wells

The company that makes this product needs to ensure that their labels are applied correctly. What I got had the flow direction arrow pointing in the wrong direction. Luckily I stayed in the basement for a while after the installation and was able to shut our drain pump off immediately when it started spewing water all over the place because the check valve was pointing the wrong way. If you buy one of these, test the valve yourself to make sure the arrow is pointing in the right direction.
