Browse our collection of sump pump swing and check valves and find the right products to protect your home against flooding. Sump pumps install underneath your home in the basement or crawl space and remove excess moisture or water that builds up. Durable check and swing check valves keep your sump pump operating in top running order. Find swing and check valves in PVC, cast iron, plastic, and other durable materials that can handle water flow without corroding or rusting over time. We offer high-quality sump pump swing and check valves from Warren, American Granby, Zoeller, and other top brands.
A sump pump check valve should be installed close to the floor level in the ground so it's easy to service. This placement minimizes the distance that the water has to travel back down after each pump cycle.
Install the check valve about 2 to 3 feet above the top of the sump pit so it's easier to access.
No, without the check valve installed, the water will drain back into the sump pump pit liner, causing the water level to rise and cause stress on the pump.
