Customer Reviews

1-1/2 in. Check Valve Kit-DISCONTINUED is rated 5.0 out of 5 by 5.
Rated 5 out of 5 by from Worked perfectly I loved that Home Depot's website prompted me to consider this as an option when I had selected the Wayne sump pump. This part fit perfectly...and not having to search for it was super convenient. For a check valve it seemed a little expensive (which is why I only give it 4 stars for value), but the ease of finding it made it worth not looking any further for me.

Rated 5 out of 5 by from Yep, it Works! It's a check valve, stops the back flow of water. Mounted it 18" above the pump as per manufacturers instructions, and there you go!
