Product Information
- 22MMA non-return valve (NRV), also known as a check valve, in a geyser system (or any plumbing system) prevents the backflow of water.
- Specifically, it ensures that water only flows in one direction, preventing heated water from flowing back into the mains line, protecting the mains supply and the geyser itself.
