Doesn’t the water freeze later on the sidewalks and cause possible liability issues?
yes it does, cracks panes occasionally as well.
This is not a pressure washer. You need only a trickle of water. The water doesn’t even make it to the sidewalk, which by the way, is always covered in a half inch of salt anyways.
We’ve never ever broken a pane with even steaming hot water.
4 cracked in total 2 last year 1 in spring 1 in fall. water was barely warm it’s not thermal shock it’s from a flaw on the edge just like a chip in a windshield might be fine for years and then a crack runs from it right across. when it happens you canseee it creeping out from the side sometimes and wandering up or down or sideways.
