Hi
The central heating pipes directly under our bed tend to go ping very loudly when the heating comes on due, I presume to them expanding and chaffing on the fairly tight notches in the joists. Since I have the floor up (Grrrrrnnn 8'x5' chipboard panels with plaster right on top Argh!) I am toying with the idea of melting wax into the notches to lubricate the pipe/joist interface.
Does anyone else have a better solution or indeed and reasons why the above wouldn't be a good idea?
Thanks
Ross
