The Brew Cabin

I had a site visit from my building control officer yesterday to inspect some drainage I am putting in around a new kitchen extension and he was happy with what I am doing and with the bends involved. But after he left I suddenly realized I am not sure which side of the bend to put these inspection chambers. I couldn't find anything in the building regs and I am loathed to ask him in case he thinks I don't know what I'm doing - which is a fact.

Any suggestions?

What do you mean by "which side of the bend"? Inspection Chambers, as well as access chambers and manholes are usually 'centred' over the key fitting, whether this is a bend or a junction.

There are some specific requirements for larger diameter pipes when used for public sewers which stipulates access space and footholds, but for Part H pipework, which is what you'll be involved with, then just try to centre the chambers.

Thank you for the reply Tony.

The main bend is in an awkward place to put the inspection chamber directly over it.

I read the building regs as 'at or near' a bend or change of gradient and thought I could put one slightly to one side or the other.

I will try to work it out as you have suggested.

Thank you

The drains from our house - in six inch SGS pipes - go through a 90 degree bend halfway down our garden. From experience I would say always have an IC after If there is a blockage and you are rodding in the direction of flow you have to dig through all the crud that has built up behind the blockage, and this can often compact theblockage. If you rod from the downstream end you get to the blockage first - but you have to be fast on your feet once you clear it if you have 90 feet of s**t sliding down towards you.

Thank you for your reply Danesis.

Sorry to be late in thanking you - I have been away.

Yeah, that makes sense. I will site them down stream as you suggest. The Building control is fine with either way as long as I am near it.
