Description
The 27mm riser pipe is an internal component designed for compatible 14″–18″ FRP water-treatment vessels with a 2.5″ top inlet. The riser pipe connects the bottom distributor or strainer assembly to a compatible manual or automatic filter head, providing the central pathway for water between the filter head and internal distributor assembly.
It is suitable for a range of water-treatment applications, including activated carbon filtration, quartz/sand filtration, water softening and other media-based filtration systems. When installed with the correct top and bottom distributors. When installed with the correct top and bottom distributors, the complete assembly helps direct water through the filter media while helping prevent filter media from entering the water outlet.

Applications:
The riser pipe can be used as part of FRP vessel assemblies for:
1. Activated carbon filtration:
Used inside carbon filter vessels to provide the connection between the internal distributor and the control/filter head.
2. Sand / ouartz filtration:
Used in media filtration vessels containing quartz sand or similar filtration media.
3. Water softening:
Can be used in compatible FRP softener vessels containing ion-exchange resin.
4. General media filtration:
Suitable for compatible FRP vessels used for various water-treatment media.
5. Water purification systems:
Used as an internal component in domestic, commercial and other water-treatment systems where the vessel and valve specifications match.
How the riser pipe works:
The 27mm riser pipe is an internal component designed for compatible 14″–18″ FRP water-treatment vessels with a 2.5″ top inlet. The riser pipe connects the bottom distributor/strainer assembly to a manual or automatic filter head, providing the central pathway for water between the filter head and internal distributor assembly.
It is suitable for a range of water-treatment applications, including activated carbon filtration, quartz/sand filtration, water softening and other media-based filtration systems. When installed with the correct top and bottom distributors, the assembly helps distribute water evenly through the filter media while preventing filter media from entering the water outlet.

The riser providing the central pathway for water between the filter head and internal distributor assembly.
During filtration, water passes through the filter media and is collected/distributed through the internal distributor system. During backwashing, the flow direction is reversed to clean the media. The top and bottom strainers/distributors are important because they help prevent larger particles and filter media from leaving the vessel. .
