Rectangular drain pipe

Hi,

I have purchased a water butt and am trying to connect it to my drain pipe, so I can divert the rain water into the butt, to use in the garden.

However, have hit a problem in that my drain pipe is rectangular, and all the diverter kits for water butts seem to be made for round pipes.

Anyone ever get a diverter for a rectangular drain pipe?

Thanks,

Thanks for that, but these dont match what I need.
