Thursday 30th

Installed all the pipes and conduits into the trench after sliding 2 x 22mm plastic plumbing pipe with foam insulation (25mm on flow and 19mm on return) into the large conduit (tried insulating with rockwool and gave it up as a bad job!).

They are from left to right :- Data, rainwater1, compressed air, rainwater2, mains water, central vac, spare, solar water & electricity.

Friday 1st Oct

Started by filling trench to approx 300mm above conduits then placed warning tapes (100mm wide polythene printed with warning messages about water & electricity below) along the trench. We then filled the trench to the top.
