I decided to do some WEB searching, and found this: Mobile Home Repair. I'm gonna assume your manufactured home is a mobile home.
If it is, you're in luck! Go to the above WEB site and you'll see that this month's Topic-Of-Discussion is Frozen Pipes! I think it would be appropriate to add your question there if you don't get any help here. Be SURE to ask about how to prevent this in the future. Also, say more about the piping, like where it goes, how deep, is it exposed, and also say where you live. Remember, no one can see your situation.
