Check-valve and anti-smell valves for building
Buildings can experience problems with the backflow of water through the network, which can result in extensive damage to the property.
NORHAM’s non-return valves serve to prevent this damage by stopping flooding through the network in cases of heavy rain, storms or floods.
The anti-smell valves help to stop bad smells coming from the manholes of surface water drains, originating from the combined sewer system connections.
