Backwater-Valves

A backwater valve is a one-way safety device that stops sewage from flowing back from the public sewer into your building drains. It’s a common safeguard for basements, low-lying homes, and flood-prone properties, and it’s required by plumbing code in many situations. 

NDS is a trusted leader in water management. Across residential and commercial jobs, NDS valves are known for durability, reliable backflow protection, and easy installation. Models include PVC and an ABS backwater valve option, with straightforward pipe connections that fit standard PVC pipe sizes; that means less time on site and fewer system issues.
