Should downpipe connect directly to the running outlet?

[DIYNotIan]

Hi all

I've had to move and reconfigure a downpipe because I've fitted a new kitchen extractor and the vent is slap bang where the downpipe was. The guttering is ogee and the downpipes/bends are square....

I bought a couple of 112.5 degree offset bends, thinking that's all I'd need. The bends will need to sit lower than directly beneath the running outlet, and I thought I would be able to use a small piece of downpipe between the running outlet and the bends. But the downpipe doesn't fit onto the running outlet. I've watched some videos and on all of those the downpipe fits directly. Mind you, most of the videos were for round guttering.

So is it because I'm mix and matching different brands? Or is it normal for square downpipe not to fit directly?

I'm wondering if this will solve the problem?

And if so, is it a bodge or is one of these always needed in this scenario?

It's not a bodge, it's why these are made.

Excellent, I'll get one on order then. Thanks for confirming. I thought it was what they were for but then got confused when no one mentioned them on youtube vids I was watching, and instead said the downpipes should connect directly.

Cheers

Some do, some don't, depends on brand and style of running outlet
