Practical types - we have a diverter on a rainwater downpipe presumably set up for a very low rainwater butt (~2 foot off the ground). We want to get a much bigger butt (because we like them and I cannot lie). How straight forward is the process of (presumably) taking out the existing diverter and repairing that section of pipe and then fitting the diverter in the higher section where we will now require it? Or am I missing something? Cheers

I wouldn't even bother repairing it.

1. Purchase new downpipe
   
2. Remove the section of downpipe below the diverter
   
3. Remove the diverter
   
4. Cut the remaining section of downpipe (which was above the diverter) at the new required height.
   
5. Refit diverter at required height
   
6. Cut length of (newly purchased) downpipe to fit below diverter and fit it (adding new downpipe clip(s) if necessary)
   
7. (If there was one originally, refit shoe to bottom of new downpipe section)
   
   

Edit: Erm, yeah, what you just said ^ up there. Down pipes don't necessarily need cementing. Mine are just held up because the shoe sits on the grate of the drain below and by the tension in the downpipe clips. If you do need to hold them together a little stainless screw works well. It also has the advantage that you can then locate any blockage from water coming out of the joint above it. If you cement the joints then they will be completely sealed and any blockages will back up much further.
