Frozen Pipes

[Marsha Wallace]

HI, I did a very foolish thing. I forgot to let the faucet drip the other night when it got down to 10 degrees below 0 (windchill), and the pipes froze. I did have heat tape and it was working. I am wondering that it has now been 2 days and I am crawling under it today with an electric heater on my lunch hour.
Does anyone have any suggestions?
I think I'll take my blow dryer too. I'm a bit nervous that my pipes will burst and if that happens well, lets just say I'll be moving in with my best friend probably. I love her, don't get me wrong, I just don't want to live there. LOL
Please help.
Thanks,
Frozen in Illiinois

I think your pipes are freezing somewhere besides the inlet.
Are there holes in the bottom board and missing insulation in the floor?
Check that out.
If you can't thaw after a day, your in trouble!
