Effective Flood Prevention
Backwater Valves (non-return valves) are used to prevent flooding caused by the backflow of storm water and sewage. Backflow can be caused by intense rain, thaw or floods. The valves prevent backflow into residential and commercial premises via the drain systems, toilets or sewers.
The backflow valves can be installed in horizontal sewage pipes within the building or in manholes/access chambers outside the building.

The valve comes in standard sizes to fit UK pipes at 110, 160 and 200mm

Lockable and Easy to Service
