RainDrain A15 is designed to be suitable for multiple applications, all of them domestic, for example: Patios, Paths, Courtyards, Thresholds and Perimeters, and Pedestrian Areas

There’s a range of accessories suitable for use with RainDrain, including a sump unit, outlet end cap, closing end cap and horizontal foul air trap.

There is also a choice of plastic and galvanised replacement gratings.

The RainDrain Sump Unit functions as a debris‑collection chamber that traps silt, leaves, and other particles to prevent blockages in underground pipework.  It can be installed as a catch pit or provide a horizontal outlet to a 110 mm PVC‑U pipe. The sump also support easy maintenance of the drainage system.  By collecting debris in a single accessible chamber, the sump makes it easy to maintain the system—simply remove the cover and clean out the chamber periodically.

Yes, the RainDrain channel be cut to size; however, the channel joints must be properly sealed if a watertight joint is required.

The standard corner unit comes complete with a galvanised steel grating. Alternative gratings can instead be cut to length using: a fine‑tooth hacksaw for plastic gratings, or a metal‑cutting saw/angle grinder for steel, galvanised steel, or cast‑iron gratings.

No. The horizontal foul air trap cannot be connected directly to the channel; it can only be connected to the horizontal outlet on the sump unit.

It may be possible to create this connection through on‑site modification; however, we do not offer a standard fitting for this application.
