Product Description

Leaf Separator Guard for Square or Round Downpipes

This Leaf Separator from 3P Technik removes leaves and other debris that have travelled down your downpipe before they enter your waterbutt or drainage system. It comes complete with adapters to suit 65mm square downpipes and 68mm, 80mm, 90mm and 100mm round downpipes.

The downpipe leaf trap is easily installed at a height convenient for leaf removal from time to time - no more standing on ladders to reach the guttering. It ejects leaves, moss, twigs and other debris from the downpipe and allows the cleaned water to continue down the guttering.

This device is popular where people want to filter out leaves, moss, twigs and other larger particles before soakaways, underground pipework, drains to guard against blockages. Can also be installed before waterbutts that are fed from directly into the top of the water butt from the downpipe (like the Wall Mounted Waterbutt), so that sludge doesn't build up at the bottom of the water storage tank.

The Green Lid can be closed when desired.

Once cut, the downpipe simply slots into the Leaf Separator. The internal dimension of the top of the Leaf Separator is 107mm (see photo), easily fitting UK 4" downpipes. Downpipe brackets may have to be repositioned to. The UK adaptor can be fitted at the bottom of the unit to ensure a good fit with smaller downpipes too. 

Note: The adaptor is round not square. When using with a square downpipe, the round adaptor simply slots into your square downpipe, there will be gaps in the corners, but that will not effect the water flowing into the downpipe.

    Suggestion of an improvement is to supply a rubber boot for the top as this finishes it off very well .
