Stop leaves blocking drain with this downpipe leaf filter

The Leaf Separator Compact, simply and efficiently separates and then ejects leaves from the water passing down the downpipe. No more cleaning blocked downpipes!

The Leaf Separator Compact discharges leaves from the front while allowing rainwater to pass into the downpipe as usual.  It can be a real cost-saver, especially where rainwater is discharged into underground drainage systems or to a soakaway, which would otherwise block over time and need costly refurbishment. 

Fits 68mm to 90mm round (diameter) and 65mm square downpipes (most UK plastic downpipes are 68mm round or 65mm square).
For larger 4" (100mm) round and 75mm square downpipes please see the Leaf Separator Filter.

This leaf guard can be installed at any suitable height to allow for the discharged leaves, moss and twigs. So no more standing on ladders to reach the gutter to unblock the downpipe.

This is not a formal filter for rainwater harvesting systems, however,  it is intended to protect downstream pipework, ponds, or soakaways from blocking up with leaves etc, or can be used as a simple pre-filter. If a fine filter is required instead, or in conjunction with, then do have a look at the superb 3P Filter Collector with Universal Link Kit or the 3P Rainus Filter.

With lower adaptor (included) this leaf guard fits square downpipes (65mm), and round downpipes from 68mm to 90mm outer diameter. Available in two colours (black and white to suit your guttering. For square downpipes the unit fits into the downpipe, there will be gaps around the downpipe corners, but the water flows perfectly well into the downpipe.

The Leaf Separator is designed so that the downpipe fits inside the unit.  The pipework above should not be supported by the Leaf Separator. Downpipe brackets may need to be re-positioned.
