The Deep Freeze

We are in the deep freeze right now.  It is -40 degrees outside and so crazy cold.  Well,  that is really not a problem so long as the house is warm.  And, for the most part it is.  The only problem is that the drainage pipes coming from the kitchen seem to have frozen up and that is a royal pain at the moment.  What to do!!?  Boiling salt water has not done the trick even if I thought it was.  It did go down the drain but I soon discovered it coming out the dishwasher and nothing was solved.  Ahgh!!  I guess we'll figure this out.  Doesn't seem like a great Sabbath activity but it is necessary so here we are with wrenches and water, and pipes.  Wish us well and say a prayer for us while your at it.  Thanks.
