Hi all, has anyone ever fitted a rainwater diverter onto a cast iron downpipe? Is it tricky?
8th one down on the right...
oh, so the normal kit I got from wickes won't fit then?
The stuff you have will be for plastic, you may get lucky, probably not.
what can I do ? I am stuck !!
You could change your down pipe for plastic.
possibly an idea, thanks for the help it's much appreciated where do I change it from? There is a hopper head that feeds it
Cast is 65mm plastic is 68mm so will probably fit. However, it will likely look ****. Just order the diverter from the link. 48hr delivery, job done.
thnaks for your reply. Does the cast iron diverter kit have to be joined by the traditional way though as I have not caulked etc before and not sure how to?
If I did use the normal one, as you say it may look s**t, even if I did "try it", after cutting the 30mm of pipe from the down pipe, would it be possible to slide the diverter on without removing the bottom part of the downpipe from the wall?
You don`t caulk cast rainwater pipes they just fit together loose - the big pipe nails hold them firm enough , even for cat burgulars. Either way you`ll have to take the pipe away from the wall to insert a diverter - you can use screws and washers instead of pipe nails when replacing
ok i see! thanks for your help again The only problem is from the cast iron rainwater diverter in the link, the connection to the water butt is on the wrong side for me!!
Not only that, but if I cut the downpipe brackets to get the lower part of the downpipe from the wall, it will look a right mess after surely??
you have to cut the fixings from behind the brackets - or maybe lever them out
o tank or your help ! One last q - what a normal plastic downpipe clip fit a cast iron pipe as well, in case I need to secure the lower pipe from the diverter back to the wall? Or are there special clips?
