1 Questions about Square Downpipe Filter

  1. How do you get rid of the collected debris from the filter?


    1. Hi Philippa,

      You won’t need to get rid of the debris yourself from this downpipe filter. All the debris fill fall down the downpipe into your drains, it won’t collect it for you to then get rid of.

      Thanks, Gerty
