eksasol: One time during the winter in New York my heater stopped working and the water pipes got so cold it cracked due to temperature changes, maybe with hot water running through it or with the ice build up. So the basemen was flooded, fortunately the firefighter people drained it.
When the heater was fixed after a while, I swear I could feel my bones warmed up in my body.
Yeah, losing power/heat anywhere where temps dip below freezing for prolonged times can be a problem for water pipes of any type, That's why I have had a generator for quite a few years now, and also installed a couple in-wall digitally controlled electric heaters in my home. They supplement the oil fired boiler heat, as well as helping to keep energy cost down when fuel oil costs soar. I'd love to escape New York and move somewhere a bit warmer, but just not in the cards for me in the immediate future unfortunately. On a kind of silver lining type of view...burst pipes do create more work for me, being a contractor.
Tcharr: Water is a fluid, and it does not compress. When it freezes to ice, however, it expands into a crystalline lattice. That is what can crack pipes and other things. :)
Exactly...it's when the pipes thaw, and the ice is no longer plugging the crack it created, the leaking and flooding happen
