MTA - Model MwStop -Check Valve
MwStop APPLICATIONS There are numerous causes for back-flow. Heavy rainfall, pipe blockage, operational breakdown of the pumping station, water back-flow from water bodies or other overload of the sewage system might exceed the capacity of the sewage system. MwStop® check valve protects against water back-flow, intrution of water and foreign substances into buildings as well as into sewage and rainwater pipes. Moreover, MwStop® check valve is an effcient protection against inconvenient smells.
MwStop® check valves effectively protect against backwater, flooding and additionally against odour nuisance.

The MwStop® backwater valve reliably protects your building from high water levels, flooding and overflow. The integrated membrane reliably closes the pipe leading to the property in the event of backwater, e.g. during heavy weather events or failure of the pumping station. This reliably protects your building from flooding due to backwater.
Bad odours from the sewage system are efficiently prevented from entering the building by the MwStop® backflow valve. The innovative membrane also closes the pipe when it is not in use, thus preventing unpleasant odours. Another positive effect is the optimal protection of the property against pests penetrating through the sewer system.
The MwStop®check valve can be easily installed in any standard pipe size. Retrofitting in existing networks is also possible at any time in the simplest way. As a result, the backwater valve can be retrofitted without any problems not only in new construction projects but also in existing buildings.
As soon as water flows in the direction of flow through the pipe to be secured, the MwStop® check valve is subjected to increasing pressure. This pushes the diaphragm upwards so that the water can flow freely below the valve. The rising water pressure triggers a controlled surge flushing, which consequently ensures the regular removal of existing sediments. On the other hand, the tight seal reliably prevents unpleasant odours in the pipe network. As soon as water flows against the direction of flow through the pipe to be secured, the MwStop® check valve fills up and consequently effectively prevents the water from backing up. The backwater height varies depending on the MwStop® model (maximum 8,000mm).
- Backflow prevention
- Odour control
- Surge flushing
- extremely low pressure drop
- without moving parts
- for all pipe materials and sizes
- very simple installation
- long service life
The design, which has been reduced to an optimum, and the use of high quality materials of the MwStop® check valve are designed to convince with a long service life. In addition, the MwStop® check valves are an effective add-on for every object.
