Just a couple of questions. I'm installing a new bathroom and so need to fit and plumb in a new soil pipe & IC. I've dug a hole (see photo) but have a couple of questions. There are a few additional pipes which complicate things slightly. I'd like to install the IC in the lower left area of the hole but the mains water supply runs directly underneath the pipe. Is this going to be a problem or can i just position the IC where the existing pipe drainage pipe is above the water supply. If so any thoughts on bedding in to avoid damaging water pipe. (will this pass BC?)
Also can i run the soil pipe into the ground then at a slow gradient down to the IC or does it need to reach a minimum depth before i put the bend in and aim for the IC?

hi jimbo, welcome. There is a few bits & pieces there. I wouldn't think the copper pipe is your mains supply it only looks like a 15ml, maybe it's a spur to an outhouse, or summink? Is the plassy pipe capped off & is rusty one fractured. You need to confirm they are redundant, or not.

Thanks for the reply. I'm pretty sure now that the copper pipe is mains supply as enters the house directly in line approx 1m away from the hole. Googling this it seems this isn't that unusual although not ideal. As it goes underneath our shed and we dont really have a pressure problem i'm planning on leaving it as it is. As for the rusty pipe still confused. I can't see any obvious fractures but it's so rusty i'm surprised it's still there. My guess is an old water pipe but i wouldn't like to say for sure. The plastic pipe definately used to be the gas feed, i'm assuming there's a smaller pipe inside it's been cut as it comes through the wall of the house and sealed with some gungy sealant type stuff so i'm presuming this is redundant but i think i'll call the supplier to check.
Thanks for your help.

Thanks again for your advice. I've been having another look and located both ends of the gas pipe which are totally disconnected. The rusty pipe has a 5mm hole in it and nothing leaking so that must be redundant and the copper water supply is 22mm so good news! I can crack on with the digging.
Like i said before i'm going to be installing a new soil pipe and inspection chamber. I'm very much a novice at this so just taking it slowly but any tips & suggestions on installation and satisfying building control would be very much appreciated, especially any info about required testing?
thanks again.

1 more question: does the IC need to be a minimum depth?

I doubt building control need to know about what you're doing and with regards testing I'm pretty certain that you wouldn't need to do that either. You should aim for at least 10inches of depth but the pipe you're connecting to will set the height for you. With regards all the pipes etc you have got a bit of a mess there but I'd rip out anything that isn't in use. Be carefull with that rusty pipe something tells me it's your electric and the pipe is the conduit it's run through. Water normally is in lead pipes which don't rust it's unusual to see them in steel. Does the ic neede to be sited there or could you move it further over.

thats good news, you got off lightly :;): no minimum depth for ic but you are governed by existing pipework anyway.

your falls to existing drains will determine that
