I have a 68mm downpipe that drains water off my shed onto my patio which then falls off the surface to a public road drain. However, I've noticed that it's washed away the sand underneath the stone that lies underneath the 68mm downpipe. My idea is to attach a short length of 50mm hose pipe to the 68mm pipe, and divert the water to the grass on the side. Any ideas on how I can couple these different pipes together as cheaply as possible? Cheers, JMc
Can you not make a decent job of it and use more of the downpipe incorporating an angled connector across to the grass area?
Might work. https://www.pipekit.co.uk/hunter-black-spigot-reducer-68mm-x-50mm.html Other than that, a flexseal adaptor could be cobbled together with 50mm waste pipe https://www.plastics-express.co.uk/...MI28b2npPf5QIVENHeCh1TjgV8EAQYASABEgLz4_D_BwE
Thanks for the ideas so far. I was hoping there might be a 68mm blanking plug which I could drill a 50mm hole into; but this doesn't seem to exist. So far I'm tending towards using a rainwater diverter such as this: https://www.screwfix.com/p/floplast-rainwater-diverter-70mm-black/27866 which does the job neatly, although a little on the expensive side. The hose doesn't have to be 50mm.
I chose 50mm as a standard hose size such as this: https://www.watergardeningdirect.co...77WtZMQYiirnUfw2IFYF-mVP0hTOWgJxoCmLIQAvD_BwE, but any standard hose size will do.
Still not sure why you can’t connect more downpipe (with an angled connector)! Will look much neater
