Description
Non-return valves allow sewer or surface water materials to freely flow in the direction of the systems mains but block backflow of those materials in the opposite direction in instances, such as, flooding.
Featuring a simple push-fit design, NRVs are easy to install into the desired inlet in a property’s manhole chamber. Installation can be achieved in minutes, without any specialist expertise.
Users also benefit from protection against rodent infestation. The stainless-steel reinforced flap helps to block rats and other rodents and insects from travelling up pipes and into homes and commercial buildings.

- Unobtrusive to natural flow.

- Two sizes available to suit DN100 and DN150 pipes.
- Universal for all pipe materials within the products size range.
