Prevent flooding problems with a good quality NRV.
Ideal for situations, like mine, where water drainage from roofs goes into a stream via underground pipes and it is necessary to stop return flow in flood conditions. Already had 2 installed and now putting further 2 in place.Read full review...

Does what it says on the tin
Very nicely designed and made. My only concern is that debris could prevent it closing properly. Otherwise excellent!
