lowest safe temperature for indoor plumbing??

Our furnace died (7year old goodman..) today, so we all came home to a frozen house this evening.
Got on hold of a company and the earliest that they can come out to install a new unit is on Monday AM. Guess, we are going to be spending this weekend upstairs only..

Anyway, the current temperature of our 1st floor is at 50F. With the weather being so cold outside, the temperature will likely fall lower over night., I'm worried about the plumbing pipes on this floor (kitchen, powder room, laundry room). How low of temperature can the pipes handle??? Any suggestions as to what we can do to prevent possible freeze?

 

For any pipes in the outside walls, you may need to open the faucet to a trickle. (And check that it continues to trickle.) For pipes in inside walls, you should be OK if the rooms on both sides of the wall are above freezing.

 

Agree with QZPMAL - also open the cabinets up so the inside air circulates around the pipes - ive heard this one before
good luck!

 

Do you have a fireplace? Some heat, even isolated to a couple of rooms, will help the pipes. Open all your faucets to a steady trickle but use warm water. When water freezes it expands which is why pipes burst.

Thank goodness you still have power...and hopefully electric blankets
