[quote author=Lectrician link=1120075689/0#1 date=1120075978]Being a sparky, I know bugger all about the regs.......BUT
All i see is copper pipe sleeved (in manufacturer) in white PVC. This is clipped diect to walls, and buried in the soil.
I expect, as with out lecky cables, you should burry in a bed of sand, and use warning tape.
Here comes the plumbers advice...... [/quote]
For a sparkie that was dam good
10mm plastic coated pipe covered in sand, fire valve has to be positioned external to the building with a capilary tube going to the boiler or a remote.
