Curved downpipe

[James Carmichael]

Hi all,

A bit of a long shot question.

I need to add a new downpipe to the side elevation of my house to collect rain from a new gutter where, previously, it had been falling onto a neighbouring roof then overflowing their gutter 9Increasing their gutter size is not an option). The only available way to get rid of the water is to route the new downpipe to a surface water drain around the front, so it'll need to go down then track horizontally and around a corner along to that.

Here's the difficulty. It's a listed cob building that has, as cob buildings do, a very curved corner. A 90 degree bend is going to stick out and look awful. It's also directly onto the road so anything hanging out is likely to get in the way of pedestrians at least.

Stacking flexi or 45 degree bends to walk it round the corner is going to be really unsightly.

Ideally, I need to find a way to run a curved downpipe round the corner following its line.

Our conservation officer is great and recognises the need so I think we'll be ok with any material. We have plastic and CI now. Ideally, I'd go cast alu and replace the lot.

Anyone got any clever ideas for curving a downpipe, better options, or any suppliers that could fab such a thing?

Thanks

Unfortunately it's all currently buried in scaffolding ...

Go round the corner first then down.
Other than that you could perhaps try heating and moulding a bit of down pipe to suit. Never tried it with that size pipe but can be done with smaller diameters

Flexible pipe of a suitable diameter to join the various straight lengths.

Only two 45’s are required for a corner , what’s unsightly about that?

Or this ?

He's explained that the "corner" is round and it sounds like 2x 45's or that bend would still be too sharp to follow the profile of the corner.

All I can think of is a company that makes custom stainless steel exhaust pipes who would be able to produce the correct curve and swage the ends to fit standard rainwater goods.

Or Chinese rubbish, but I'm not sure how that would look on a listed building.
