Riser Pipes & Strainers

Riser Pipes & Strainers are essential internal components for FRP pressure vessels, ensuring proper water distributionand media retention within filtration and softening systems. These parts form the internal flow path that allows water to pass evenly through the filter media and exit cleanly, without loss of media or uneven flow.

Whether you're building a custom filtration system or replacing worn internal components, our range includes central riser pipes, top strainers, and bottom distributors, all compatible with standard vessel sizes from 6” to 24”. Made from durable food-grade plastics, these components ensure long service life and efficient backwash performance.

This collection includes:
• Riser Pipes – Available in multiple lengths (cut to suit vessel height)
• Bottom Strainers / Distributors – Slot or hub & lateral designs for media retention
• Top Strainers / Baskets – For top-mounted valve assemblies
• Internal Pipe Kits – Pre-assembled sets for quick installation
• 1.05” & 1.25” OD Pipe Options – For most standard valve ports
• Threaded & Push-Fit Connections – For compatibility with Runxin, Fleck, Canature & more
