I'm renewing a small failed zinc parapet roof with fibreglass. It is drained through a small tube formed from the zinc. The tube is only about 35mm wide and the top regularly gets blocked with leaves so I plan to install something 50 or 60mm. The problem is it's tucked tightly in an awkward corner so a spigot unit wouldn't fit.
Suggestions for best things to use for the new outlet? Maybe something tapering so the GRP can be folded into it?
