Dear All,
Sorry for my post in English as I am not yet comfortable in Swedish. Please feel free to write your answer in Swedish, I can translate.
I engaged a VVS company to do my underfloor heating of my new villa. They are using the 16x2 LK PE-RT pipes in LK floor heating strip. Wherever there are bends, I see small damages on the pipes due to friction with the floor heating strip. (Please see the pictures.).
The plumbing company feels this should be ok, but I am tensed because we will do concrete casting on this and the damages will remain forever.
Please advise.
