Kevinmc Posted November 18, 2004 Share Posted November 18, 2004 As an aside to my local question elsewher, how prolonged does a cold spell need to be before damage occurs or a pipe is likley to burst. For example if it drops to minus 5 overnight but the daytime temp reaches plus 10, is damage likely to result ? Link to comment Share on other sites More sharing options...
Anton Redman Posted November 18, 2004 Share Posted November 18, 2004 Too many variables. Are the pipes above or below ground, are they made of plastic or copper, how big are the pipes are the pipes regularly in use. What was air temperature beofe cold spell began.Broadly our house reached minus 13 a couple of years ago. Exposed plastic feed pipes to houses froze. We had drained our system but not emptied the hot water cylinder which was in the cellar. Suggest you ask you neighbours. We had no frost damage, some houses had their mains freeze and were also damage free. Link to comment Share on other sites More sharing options...
Kevinmc Posted November 19, 2004 Author Share Posted November 19, 2004 Appreciated Anton.It's not normally a problem, I just forget to set the frost thermostat. Never had a burst before, so not sure how likely it is. All the pipes are internal, copper around the boiler feeding into ancient iron/steel, but all internal. If the serious cold holds off till Wednesday, I'm alright Link to comment Share on other sites More sharing options...
Nick Trollope Posted November 19, 2004 Share Posted November 19, 2004 It also depends on where you are! Around here (22) the temp is unlikely to drop below 3 degrees before Wednesday... Link to comment Share on other sites More sharing options...
