Drainage Non-Return Valve
Backflow flooding can happen to any property, even if the area is not threatened by floods. Sewers become blocked and waste water is forced up into your bathroom, kitchen or lavatory.
Watertight’s internal Non-Return Valve is an affordable way to banish this threat forever. It is simply pushed into the open end of the drainage pipe, saving hundreds of pounds when compared with the cost of installing a conventional non-return valve.
Why choose Watertight’s Non-Return Valve?
||• Backflow flooding due to floods or sewer blockages
• Vermin entering the property via the drains
• Noxious fumes from the sewer system
||The valve pushes directly into the end of the outlet pipe where it opens into the inspection chamber. It works exactly like conventional valves, allowing water to pass out through it but shutting swiftly and firmly when the flow reverses thanks to our unique wrap around seal.
