Insect Protection & Odor Control

Prevent insects and unpleasant odours from spreading through sewer and drainage systems. With the right check valve, both intrusion and odours can be stopped without restricting normal water flow.

When the sewer system becomes a pathway for insects and odours

Sewer and drainage systems can provide pathways for insects and unpleasant odours. Insects can travel through the pipe network and cause problems, while odours and gases from wastewater systems can spread through pipes and outlets into homes and other areas where people spend time.

With the right protection, insects and odours can be stopped without restricting normal water flow. The WaStop check valve features a flexible membrane design that opens when water flows in the intended direction and seals against flow from the opposite direction. This provides effective protection against unwanted backflow, odours and insects in both new and existing systems.

    Family in Sjöbo gets rid of smelly hydrogen sulfide

    We installed a WaStop in an existing well between the house and the pipe from which the sulfur smell came. The WaStop is completely sealed against odor and backflow. Today, the sulfur smell does not reach the house but stays in the pipe downstream of the WaStop.

    The family living in the house is satisfied and the municipality has solved the problem.
