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.
