Hi.
I'm about to start groundworks for building an office at the other end of the garden. We're digging a trench for water, and will install ducting for comms and electricity at the same time. We're also debating putting a gas duct in, as we may want to run gas as well at some point later, and I'd rather put the duct in now rather than have to re-open the trench later.
However... the trench will run for approximately 70 metres around the garden perimeter (avoiding septic tank etc), which is fine for cables and water, but will that work ok for gas pipe? And what size pipe would it need to be for a run that length? (My run will have corners, so just defaulting to massive pipe isn't without its own problems).
Also adding to my dilemma is that the gas currently enters the property at the front, and the ducting will be at the back. I can't go around the house. So the ducting will only be useful if it is permitted to run a pipe through the house (possibly in a small duct embedded in the floor screed??) in order to run out of the back of the house, back into a larger diameter pipe (I presume?) and through the underground ducting to the office.
So.... to clarify my questions:
Is it permitted to run a pipe for gas through a duct in floor screed just to get it to the rear of a property?
If yes, presumably it would have to be a smallish pipe (maybe 20-25mm?).
If that pipe then was then to run into a longer run (70m), is it helpful, desirable, or necessary to step-up to a larger diameter pipe?
And if so, what is a sensible size pipe for such a run? (Thus determining my duct diameter!)
For the record, I am simply installing ducting at the moment, not touching anything with gas in it. And I'm at least a year or two away from needing a gas installer, so I'm not yet in contact with one.
I hope that makes some sense?? Too many questions in my head!
Many thanks in advance!
