The RainCatcher RC is installed in the vertical rainwater downpipe. It passes runoff rainwater from the roof to the storage tank. Large dirt particles are filtered out of the water and flushed down into the drain or soakaway. Installed at the correct height, the RainCatcher RC automatically flushes excess rainwater into the drain or soakaway. The housing is made of UV- resistant polypropylene (PP). Can be mounted in round downpipes with 102, 105 or 110 mm outer diameter. 10-year guarantee. Guarantees safe drainage in accordance with DIN.
