Rainstopper - Stainless Steel Manhole Insert - Brochure

The Stainless Steel Rainstopper is a patented manhole insert designed to eliminate inflow in your municipality’s sanitary sewer system. It also reduces the infiltration of street level contaminants, while simultaneously controlling the escape of undesirable sewage odor and minimizing traffic related manhole noise and cover displacement. The insert is manufactured in the USA to precise, custom specifications from corrosion resistant 304 or 316 stainless steel. Its unique design allows the venting of sewer gases through a non-mechanical device, reducing maintenance costs by eliminating moving parts. Weighing only 10 pounds, it can be easily installed by a single person.
