OK…here goes. We have a combi boiler with a condensate pipe that runs outside to a drain. The pipe is 22mm and about 2m long. Over the past week or so in the freezing cold it has been freezing which obviously puts the boiler into reset mode.
A kettle of warm water later unblocks it, but that’s no good as we’re going away for a few days soon. I have tried lagging the pipe with ThermaWrap but it’s so cold it’s still freezing albeit taking longer to do so.
My solution is this and I need to know if there are any “experts” who think it may work. If I were to drastically shorten the pipe, say to about 6 inches would this help? My logic thinks that the less cold pipe water trickles through, the less time it has to freeze. I will also fully insulate this section of pipe too.
