Rainwater drainage runs

[Vijay]

A job I totally forgot to do was the drainage runs for my guttering to my RWH. 

 

I assume everything is done in 4" underground pipe the same as my foul drainage, but do I need inspection/rodding chambers at all, say on bends for any reason, seeing as it's just rainwater?

 

Cheers

Mine has been designed with rodding points at the far end so you can give it a push through 

you will get a fair bit of sediment from the roof

dust of tiles, bird poo, leaves. 

No ic at bends but definitely a way to get in it 

I think you can nominate to use bottle gullies with rodding points, but they are a pain to get a rod into

but then again you can always use a high pressure hose

Hello bud,

 

Do you mean just standard 45 degree rodding eyes like these? https://www.beesleyandfildes.co.uk/110mm-x-45deg-rod-eye-terminal-sq-top-spig-tail-ref-ug522/

Yep I have one on the far end of all runs

my system was designed by a hydrological company because of all the water by me

not had any comments from bco, so hope it’s all good.

Thanks Russ

We have rodding points on the land drains round the base of the slab as well so we can keep them free of clagg as well as in the rainwater runs.
