gutter leaking during heavy downpour

[mills28]

Had gutter replaced recently and now have a downpipe that backs up slightly and leaks when rain is heavy in light to moderate rain its fine. What to do pipes are 75mm on the whole house. No leaks or issues with the other downpipes.

Hi @mills28,

I wanted to zoom in and have a closer but unable to do that because the photos are quite small and low res.

I would like us to try and confirm where the leaking starts, with assistance can you poke the hose into the downpipe until it hits the elbow.

With the garden tap turned wait to see what happens and where the leaking starts to show itself.

Please come back with the results...

Cheers
