Does anyone know if it is alright to leave some residue water in the pipe in subzero winter?
Mark from Waltham Housing Authority Answered this on December 09, 2019
From my experience it is safe  to leave a residual amount of water in the pipe. The concern comes when the water left in large volume in a pipe freezes. The frozen water expands and breaks the pipe. Residual water should not do that. (more) From my experience it is safe  to leave a residual amount of water in the pipe. The concern comes when the water left in large volume in a pipe freezes.
