I've been checking in a void below our house to see how good the insulation on the pipework is prior to leaving the house for an extended period in January and February, when I saw a very long straight run of 15mm copper pipe feeding an outside tape at one end of the house. I've not measured it but it has to be 7 or 8 metres long. It is fixed at both ends by soldered elbows on the outsides of brick/blockwork at both ends. there is one compression fitting halfway along. What concerns me is what may happen in low temperatures. The pipework could contract quite considerably and no doubt pull the compression fitting apart. I had thought to put a contraction loop in the run in the form of a push-fit flexible pipe in a very slight "S".
I can drain half of the pipe quite easily but that won't remove the contraction problem and if anything might worsen it.
What are the professional thoughts?
