RIW Aqua Channel Cleaning Ports (jetting eye).

A PVC straight connector with a removable cap and rubber seal solvent welded to a male coupling. Cleaning ports (jetting eyes) are recommended for use with the Aqua channel and can be inserted at any point along its length (one every 12 linear metres), to allow for periodic cleaning of the drainage system.

RIW Aqua Channel Connectors.

Used to connect two lengths of Aqua Channel together, or other accessories to the Aqua Channel.

RIW Aqua Channel Corner Piece.

Used in conjunction with Aqua Channel Cleaning Ports for maintenance.

RIW Aqua Channel End Outlet.

Where gravity fed drainage is to be used, the channel end outlet has been designed to convert the pentagonal shape of the Aqua channel into a round aperture. This enables water to be discharged from the Aqua channel into a P trapped gully or to a soakaway.
