usually be in the outside walls, near doors,
windows and in crawl spaces under floors. If all
the water outlets in the house fail to operate,
the line from the curb valve to the house is
frozen.
2. House service pipes usually have to be thawed
by connecting one cable to the exposed pipe in
the kitchen or basement and other cable to the
curb service. At the curb, make the connection
to the valve at the bottom of the service riser,
using the curb key. Do not connect the cable to
the adjustable ground level cover as it is a poor
connection to the valve.
3. Connect the cables on either side of the frozen
section so that they complete an electric circuit.
The cable clamps must be at least 10 ft. apart.
Caution:
The cables get hot!
clear of rugs and finished floors that can be
damaged by heat.
4. Good connections are required. Clean all pipes
before connecting the cables. Make both pipe
connections
before
receptacle. Make sure all connections are tight
to prevent arcing at the clamps.
connections also get hot and reduce current
flow. Caution: Uncoil the cables. Do not
leave any cable coiled up or placed on steel
objects as the heating in the pipe will be
reduced.
5. If a good connection is made, the pipe and
cables will vibrate with a 60 cycle hum that you
can feel with your hand. After all connections
are made and the unit is plugged in, switch the
circuit breaker on.

Some Common Problems
1. Cables stay cold. Pipe does not thaw.
•
Do you have power? Check fuses.
•
Is the circuit breaker switched on?
Do you have a good connection?
•
•
Are the pipes clean at the connection?
•
Are both clamps on the same pipe?
•
Has the thermal protector tripped?
Is there a rubber coupling in the line?
•
•
Is there plastic pipe in the line?
•
Has the ice pushed the joints apart?
2. Cables get warm. Pipe does not thaw.
Are clamps on pipe, not on curb cover?
•
•
Are the pipes clean under the clamps?
•
Are cables sized properly? (Larger cables
must use larger wire size.)
3. Cables get hot. Pipe does not thaw.
•
Is there water pressure in pipe?
•
Is the source of water pressure frozen?
•
Is source water pump operating?
•
Do the clamps cover all of frozen area?
•
Can the current go more than one way from
clamp to clamp?
Thawing Times
The times in the below chart are approximate and
under ideal conditions.
depending upon type of pipe, diameter, gauge, and
length of cable, etc.
Note: Since copper pipe will not heat up as fast as
iron pipe, allow about a 30 percent longer thawing
time.
Note: Longer cables must also be a larger gauge.
If smaller diameter cables are used, current will be
reduced.
