How many Plumbers will it take to screw in a light bulb? The question requires serious consideration. Background: Our pipes to washer machine froze twice: first time plumbers thawed them w/torch (and they busted but plumbers put them back together), then they installed heat tape. They installed 12-ft tape over two separate pipes (going from one pipe then over to the other). They tape directions state not to do that. Question: (1) Should we really be concerned or let it be and hope they don't bust or cause other problems? (2) Any suggestions or tips if we have plumbers re-route pipes this spring so that they are not exposed in attic? Someone mentioned a pipe that will 'never' bust when frozen/thawed? P.S. Our area does not require plumbers to be licensed and many are not, so homeowners are left to entrust their pipes with the best plumber they can find.
