Please Note: Downpipe and filter must be purchased separately - these are not included.

Helpful information on installing your downpipe:

This model of water butt doesn't come with pre-drilled holes. But it's very easy to do it yourself! Just attach the required drill bit to your drill, and drill the hole at the same level as the downpipe's.

As long as the drillings in the water butt and the downpipe are flush, water will keep flowing from the butt to the pipe when it's full.

Opt for the Avanti Downpipe Diverter or the Rapido Downpipe Diverter for the best results.
