4 Questions about Garantia Avanti Downpipe Diverter DN 70-100

  1. Is it possible to remove the unit when we move?


    1. Hello,

      Yes you will be able to remove the unit we you move.

      Thanks, Garth


  2. The distance from my downpipe to the location of the water butt is approximately 60cm (downpipe is on the side of the house and water butt will be round the corner at the back). Is this possible with this diverter?


    1. Hi Sofia,

      Yes this should be possible, we would need to supply you with a longer piece of hose with the downpipe filter. If you add this to the notes of your order, if you do decide to purchase one, and we can make sure the we send out a longer hose.

      Thanks, Gerty


  3. Do you have installation instructions so that I can understand how this system gets installed on an existing 100mm diameter PVC downpipe? I’m not clear as to how the element inside the pipe fits through a drilled hole? Thank you


    1. Hi Tom,

      With the downpipe filter, the cup that sits inside the downpipe is made of rubber so you can squeeze it together to fit through the hole you drill into the downpipe and then it will expand to fit around the inside of the downpipe.

      Thanks, Gerty


  4. What hose type can i connect to this diverter?


    1. Hi Bogdan,

      The diverter already comes with correct hose, we can provide extra hose if needed.
