The Mid-Atlantic will experience a cold snap the next two days, roughly. I am unsure if I should insulate my basement pipes (where the air is already 40-45 F and 56 F outdoors). The basement is always chilly, and although the “furnace” is there, it is actually a heat pump which does not really heat the air like a gas or oil furnace would. And, if I do insulate, would you only insulate the line running closest to an exterior wall? Would you insulate both cold and hot water lines? (Note: There is a water line running maybe 12"-18" away from an exterior basewall [at ceiling height] and the exterior wall is above ground [at basement ceiling height]).
Also, there are no shut-off valves in the lines feeding the hose bibs. Isn’t there an insulating cover one can place on the house exterior to cover the house bib?
FYI: The last time the area saw such bitter cold in the early '80s, the house did not exist!
All advice appreciated!
