Mainline Backflow Products Inc.
Mainline Backflow invites you to see our backwater valves!
Mainline Backflow Products manufactures backwater valves designed to prevent sewage from backing up into homes as the result of a municipal sewer backup. Our products are unique in design and function: from clear view open gate to extendible valves, we cover most residential applications. We also manufacture an Inspection Chamber designed to allow municipal access to the main lateral of a building/home without needing access to the building. Our valves have a complete 'shutoff' mechanism that can be used for shutting down a sewer or for pressure testing the sewer line.
