We got about what BC said - 1 - 1.5 inches.
Saturday morning it was 8 degrees at my house. I stepped out for a bit after unloading some firewood. When I got home 3 hours later a pipe had busted and about 15 - 20 gallons of H2O was spread nice and evenly across my floor!! Luckily it was all downstairs which is block foundation w/ a concrete slab so no damages whatsoever....just a lengthy cleanup process. The pipe that busted was pex and I was able to take a few, ok SEVERAL pieces of wood siding off the side of the house to find it (turned it on for a second and listened). Then I had to borrow a pex crimping tool from my father-in law at 10:30 pm Monday night. Had it all fixed and siding back on before 1 am!! FUN FUN FUN!!
P.S. this morning it was 14 degrees. I insulated the SH*T out of those pipes while I was in there!!
