hi folks
I have to run in a hot and cold feed to the island in my new extension before the concrete floor gets poured.
I was going to use speedfit pipe run inside a plastic duct.
my question is should it be 22mm because its about 7 metres of run or is 15 mm fine for that.,
also any special protection as it will be eventually encased in 100mm concrete.
should I insulate the pipes inside in the duct as its being laid on the sub floor before insulation and underfloor heating piping goes down ?
