Waste water fittings for drain pipes and sewer systems

Wastewater fittings for drain pipes and sewer systems to ensure the backflow of liquid media and prevent odour nuisance.

Our waste water fittings for waste water and house connections

Lasso Technik AG's wastewater valves are used to secure the pipes against the return of wastewater and are designed to withstand a back pressure of up to 0.5 bar. Our wastewater valves are ideal for quick and easy installation for both industrial and residential customers. In addition, the valves are equipped with an airtight odour check valve and ensure that no duct gas can escape from the cellar. This high-quality wastewater connection also serves as a nose flap (frog-proof) and prevents small animals from entering the sewer system.

Advantages of our waste water fittings

Non-return valve for waste water as a backflow protection system in case of flooding
Wastewater valve to prevent insects and amphibians from entering the water
No odour nuisance from the sewer system
Easy and quick assembly without additional work

Functionality of waste water fittings

When water accumulates, the sealing lip of the valve diaphragm opens upwards due to the slight pressure applied. When the wastewater flow stops, the sealing lip is restored and our wastewater valve closes again. In order to avoid odour nuisances (pipe gas exhaust), the rubber membrane integrated into the valve is filled in case of backflow, so that no gas movement can escape either.
