Laying copper water pipe under floor screed?
Question:is it still acceptable to lay copper pipes for radiatiors under the floor screed??
Answers:
The pipe should be covered with Denso tape. This will protect the pipe from lime in the screed and allow for small amounts of expansion and contraction.
Id use plastic pipe, copper may corrode.
I'd lay it in a drain duct then it can be withdrawn if necessary.
Bad idea, if it ever needs a repair (which is unlikely) you will have to take up part of the floor. Much better to run it in the wall or ceiling.
It's best if you can rund them in ducting ot conduit to protect them.
It would be better to use a polypropylene line for the radient system. These will hold up better in the long run.
Only if they are protected, otherwise they will perforate very quickly.
it is acceptable,, as long as you cover these pipes up with denso, or hair felt lagging to protect the pipes from corroding. good luck.
It is acceptable , but you must wrap the pipe in DENZO tape which is obtainable from any plumbers merchant. This will prevent the cement acid reacting on the copper pipe.
