Under customers instructions I'll be feeding gas, central heating and hot/cold copper pipes partially under floorboards then through a concrete chase which will be screeded/concreted over.
What I need is some advise on protecting copper pipes in concrete.
I'm aware the lime in concrete is corrosive and have used denso tape on gas pipes before but whats the best way to protect hot and cold pipe from freezing and thermo expansion? I heard Denso tape will not work on hot pipes as the heat does something to the oils in the tape.
I was thinking about sleeving the copper in some plastic waste pipe. Would this be ok under concrete?
Also where do I find the regulations for protection of pipes in domestic properties.
