Want to run flow and return under garden to shed/log cabin about 14m from house.
Obviously need good quality Armourflex or similar. Is there a way to run both pipes in a single underground duct? Or owing to the o/s dia of the insulation, will I need two separate ducts? Not looking to over-complicate the project.
And is there a recognised depth I need to dig?
