How to Install Heat Tape on PEX Pipe in 7 Easy Steps

Step 1: Remove the Old Heat Tape

The very first step is to remove any existing heat tape from your pex pipe. This may require you to cut the old tape away using a utility knife or other sharp tool. But you have to be careful not to damage the pipe in the process.

Step 2: Measure and Cut the Heat Tape

Once you’ve removed the old heat tape, measure out your new heat tape so that it extends about 4-5 inches past each end of the pex pipe. Then use a pair of scissors or a utility knife to cut the heat tape to the appropriate size.

Step 3: Attach the Heat Tape to the Pipe

Once you’ve cut your heat tape to length, use a pair of pliers or tin snips to attach it securely around the pex pipe. Start at one end of the pipe and wrap it around until you reach the other end, making sure that it’s pressed tightly against the pipe.

Step 4: Plug in the Heat Tape

Once your heat tape is secured around the pex pipe, you’ll need to plug it into an electrical outlet or power strip. This will start heating up the pipe and helping to prevent freezing as well as keep your water flowing smoothly through your pipes during cold weather.

Step 5: Check the Heat Tape periodically

Once you’ve installed your heat tape, it’s important to check on it periodically to make sure that it’s still working properly. You may need to adjust the position of the tape or tighten any loose connections so that heat can be evenly distributed along the length of the pipe.
