The combined flusher with a non-return valve (NRV), fronts a new and innovative design utilising a simple flood defence system that keeps sewers clean from blockages and the build up of FOG (fats, oils and greases). With the addition of a non-return mechanism, the valve self-cleans and removes blockages usually associated with regular NRVs.

A revolutionary and environmentally friendly solution to drain long-term sewer maintenance and cleansing, the system utilises the considerable potential energy within a sewer to clean itself, even during periods of high flow and in storm conditions. The removal of the top plate provides an optional overflow pipe for the event of a storm surge.

With a simple push-and-fit installation into existing manholes, there is no need for a new inspection chamber; it proves a very cost-effective solution for all applications, with versions available in plastic and stainless steel. The NRV Flusher is available in a range of standard and non-standard pipe sizes, used as a standalone unit without the NRV function:

4″ (100mm)
6″ (150mm)
9″ (225mm)
12″ (300mm)
15″ (375mm)
