Moonshine Posted March 25, 2021 Share Posted March 25, 2021 I would be nervy about having those length of runs and a joint under the house, especially when you could easily bring them round the house footprint 1 Link to comment Share on other sites More sharing options...
markc Posted March 25, 2021 Share Posted March 25, 2021 Go around the outside unless absolutely necessary due to required falls and termination levels preventing the extended runs 1 Link to comment Share on other sites More sharing options...
ToughButterCup Posted March 25, 2021 Share Posted March 25, 2021 Get it out of the house as soon as possible. 2 Link to comment Share on other sites More sharing options...
Bitpipe Posted March 25, 2021 Share Posted March 25, 2021 Ours goes out and around at the back and front. Means a few more ICs but with Clarke drain covers you can have them in your drive or patio and never notice. Drain rods come in 10m packs so that should be the distance between ICs on the runs. 1 Link to comment Share on other sites More sharing options...
Big Jimbo Posted March 25, 2021 Share Posted March 25, 2021 If you can get the falls, i would always get the foul out of the house as quickly as poss. 1 Link to comment Share on other sites More sharing options...

That isn't the max distance required in building regs it is 22m i think, Table 13 here https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/442889/BR_PDF_AD_H_2015.pdf Though if the rods come in 10m packs i would out a max of 18m between inspection chambers so you have 9m + 1m overlap from either inspection chamber Edited March 25, 2021 by Moonshine 1 Link to comment Share on other sites More sharing options...
Mr Punter Posted March 25, 2021 Share Posted March 25, 2021 No that is a poor design. Maybe get your architect or whoever is doing your Building Regs to add this in because if you don't get it right it can be a real pain. 1 Link to comment Share on other sites More sharing options...

WWilts Posted March 25, 2021 Author Share Posted March 25, 2021 Thanks, all. Was relying on stuff like this: https://www.nhbc.co.uk/binaries/content/assets/nhbc/tech-zone/nhbc-standards/tech-guidance/5.3/p261---tg-5.3---y-junctions_v1.pdf Rodding eye at one end, IC at other. One soil vent at east side. Air admittance valves in every bathroom/WC. Pumping chamber situated 5m from dwelling. Because discharge from pumping chamber would go under a drive, cast iron 100DN (instead of the black MDPE 90mm suggested earlier). Might that work, despite the concerns expressed?

Russell griffiths Posted March 25, 2021 Share Posted March 25, 2021 (edited) @WWilts I think the confusion is your drawing wasn’t clear, it looks like you have just drawn orange lines and not stopped at the walls. If you mark it up with rodding eyes on the end then that looks like a much better idea. Has your architect done you drawings with layers that that can be removed, that way you can have a drainage plan without all the other junk clouding peoples view.
