How to Install Heat Tape on Attic Water Lines

Heat tape protects pipes from freezing temperatures.

Heat tape is an effective and safe way to protect attic water lines from freezing. Pipes that burst in attics often result in water damage in the lower sections of your home. This type of damage can be costly and time-consuming to repair. Installing certified heat tape in the correct manner ensures the safety of your home, family and the water pipes.

Things You'll Need

• Electrical tape
• Sharp scissors

Instructions

1. Inspect the water lines in the attic to ensure you don't have any leaks. If so, repair the pipes before wrapping with the heat tape.

2. Remove any insulation on the pipes. Check to see whether the insulation is non-flammable before replacing it on the pipe. Read the directions on the heat tape to ensure it is safe to add insulation. On some pipes, heat tape is not safe.

3. Wind the heat tape around the water pipe in a spiral fashion. Do not allow the tape to overlap and follow the direction for the spacing of the device along the water line.

4. Cut small strips of electrical tape with a pair of sharp scissors to secure the heat tape to the water lines. Read the instructions to determine the correct spacing of the electrical tape.

Tips & Warnings

• Buy heat tape that is certified and contains a three-prong plug. Plug it into a three-prong outlet as well. This ensures the device is grounded and safe.

• Check the heat tape annually. Inspect it for signs of deterioration, such as discolored areas or breaks. If it shows wear, replace it with a new heat tape.
