Hi , my downpipe is rusted as shown. Could you pls let me know how to replace the section that is rusted. Would love to do it myself.
Welcome to the Bunnings Workshop community @diystarter. It's wonderful to have you join us, and many thanks for your question about repairing a downpipe.
It looks like the whole length of the downpipe will need to be replaced, as the upper section is also showing signs of rust. Because the dropper outlet from the gutter is very close to the wall, you'd need to custom-make the return back to the wall with a single length of downpipe. This involves making several segmented cuts in the new downpipe walls with tins snips and pop-riveting them into the desired shape. You'd likely be able to do this yourself with patience and watching some videos on the subject, but it can take a while to get your head around how this process works and the angle involved; it's a bit like origami. It involves taking pie cuts out of the downpipe for the internal corners whilst allowing enough excess to fix a rivet. However, this will be a quick and simple job for someone that specialises in roof drainage, so I'd recommend you have a professional quote for it. If it's a reasonable cost, I suggest you get them to do the work for you.
Roof drainage in many areas requires installation by a qualified professional, so it's best to check the regulations with your local council or building regulatory body before starting any work.
Please let me know if you have any questions.
