Investigating the cause of a damp patch on an internal wall, I discovered a

section.

I know it would be a relatively trivial matter to replace the downpipe with
a 'nice new' plastic item; however, I'm rather attached to my original 100-
year-old cast-iron rainwater goods, and I'd really prefer to hang on to it
and repair it instead.

What would be the panel's reccommended method?

Thanks


As all you really need to do is stop it from leaking, I would lift the
upper part, clean the faces as best you can, apply gutter mastic and
join the two parts again. If it makes you feel more secure, put a bit of
flashband around the back half, covering the join.
