Frozen Pipes To Washing Machine

[Travis Hunter]

We've had a long stretch of below freezing weather recently...  I have a rental that has frozen pipes leading to the washing machine that is located in the garage.  The garage itself is not heated, but the tenant has a space heater set up there.  They are complaining about not being able to use the washer due to the froze pipes.  The water to the house itself is working fine as of now.  How would you handle this situation?  It should be back above freezing later this week and my thought is they will just need to use a Laundromat for the time being.  I did not supply the washer and dryer to this unit.  Any thoughts?  Thanks!
