We just bought a mobile home. Within the first month the water had frozen in the pipes twice due to the heat tape shorting out.

Last night, however, my husband used the restroom in the middle of the night and discovered we had no water. The first thing we do now is check the heating tape. It was on and warm, so yay there. Still, no water.

We also don't hear that gurgling sound we had heard when the pipes froze previously. I've turned off the hot water heater because I don't want the thing to burn up or blow up. Do you have any ideas why there is no water if the heat tape is still working? The temperature is in the 20s, but it has gone lower than this without the pipes freezing before.

Thanks.
