WaStop Inline Check Valve is a non-return valve designed to prevent backflow and flooding in pipelines. Works autonomously using differential pressure, with no need for electricity or manual operation. Made with a flexible membrane that allows debris to pass through and prevents blockages. Installs at any angle and does not require a head wall. Suitable for pipe sizes from 75mm up to 2100mm.
