Description
The non-return valve simply pushes into the end of the outflow pipe in your manhole and the wraparound seal does the rest.
The backwater valve allows water and waste to pass out from the property, but allows nothing back in as the valve’s resting position is shut… tight. So no backflow through your toilet or plugholes during flooding.
Equally as effective as the traditional solution the valves can be fitted in minutes and do not require any specialist expertise or equipment.
