I need to finalise this for our timber frame company prior to them installing the raft foundation (they will also site the service ducts and drains). I understand that mains water needs to come in through a 110mm duct/drain pipe to allow space to insulate the main. I want water to go back out again to a garage and/or an accumulator that I can isolate from inside the house. Can both of these water runs fit in the one 110mm duct, or do they have to have one each? Is there a more intelligent way to do it? I understand that mains electricity can come in via a 50mm duct. Can it also go out through the same duct ( to the garage etc) or do they need separate ducts, one in, one out? What about BT, (we weren't going to bother but nothing else is available and the 5G option using Huawei equipment is starting to look dodgy). I presume that needs its own duct and can't share with the electricity? Finally, as a belt and braces option, I'd like to put a spare duct in for a (potential) future ASHP, or AirCon. Would that be 110mm as well? And how would I seal it in a way that I could reopening at some later stage?
