Riser Pipe for Top Mount Multiport Valves (FRP Vessel Internal Pipe)
Riser Pipe for Top Mount Multiport Valves (FRP Vessel Internal Pipe)
Couldn't load pickup availability
The Riser Pipe is a key internal component used in FRP pressure vessels with top mount multiport valves. It connects the multiport valve at the top to the bottom strainer/distribution system inside the vessel.
This pipe acts as the central pathway for water flow during filtration and backwash cycles, ensuring efficient operation of sand filters, carbon filters, and multimedia systems.
Built with precision threading and a sealing O-ring, it ensures a secure, leak-proof connection for reliable operation.
🫗 Quick Highlights
- Designed for top mount multiport valve systems
- Connects multiport valve to bottom strainer
- Ensures smooth water flow inside the vessel
- Available in different lengths as per vessel size

- Align the top end with the multiport valve connection
- Ensure correct pipe length (flush with valve base)
- Install the multiport valve securely
- Test system operation (filter + backwash cycle)
❓ How it works
The riser pipe acts as the central conduit inside the filter vessel:
- During filtration, water flows from the top valve down through the riser pipe to the bottom strainer
- It is then distributed through the media bed
- During backwash, water flows upward through the system and exits via the riser pipe
This ensures proper circulation and efficient filtration performance.
