frozen water pipes

QUESTION: LAST YEAR WE BUILT A WASHROOM IN A HEATED BASEMENT. THIS YEAR THE WATER PIPES FROZE,EVEN THOUGH THE PERIMETER WALLS WERE INSULATED AND OF COURSE THE PIPES WERE INSTALLED JUST BEHIND THE DRYWALL (ALONG THE EXTERIOR CONCRETE BASEMENT WALLS). WE ARE TOTALLY PERPLEXED HOW THIS COULD HAPPEN SINCE SUPPLY LINES ARE BELOW FROST LINE WHICH IS 48" I WAS THINKING OF CUTTING HOLES SAY 4"X 8" ABOVE BASEBARD @ INTERVALS OF 24" SO THAT THE CAVITY BETWEEN THE STUD WALL AND CONCRETE WALL WHICH IS ABOUT 2" WOULD NOW BE HEATED I WOULD REALLY APPRECIATE YOUR OPINION THANK YOU

ANSWER:

Your suggestion of cutting openings in the walls to allow heat induction from the heated room is a good solution. A small draft can cause this problem behind the wall, even though it is below the frost line. Instead of just cutting in holes that will bleed heat out of your room all the time, you can purchase access panels that you can cut into the wall at points. Then, as colder weather approaches, you can remove these decorative squares and allow heat to enter. Be sure to reinstall the squares after the cold spell so you are not wasting heat all winter.
