Pipe Freeze Protection Basics Pipe Freeze Protection Basics
Freeze protection for plumbing pipes should be installed in areas where the air is not heated, such as crawlspaces, garages and sheds. Be sure to disconnect all of the outdoor water lines that run into the house. This will prevent them from bursting during an overnight freeze.
Applying Sealant and Insulation
Apply a sealant to any cracks or holes where cold air can enter and freeze the plumbing. Insulate the doors to unheated areas with plastic sheeting. Determine the diameter of the pipes that you want to protect from freezing. You will need the measurement when you purchase the foam pipe insulation. Fit the insulation around the pipes.
Installing Heat Tape
Protect the pipes that are at risk of freezing with heat tape. Plug the tape into an electric power source whenever necessary. Use a rubber coated tape that is moisture resistant because it will last longer.
Use a small electric heater to increase the air temperature level in the area near the pipes that might freeze. Be sure the heater is approved for safety. Lastly, turn on your faucets to allow the water to trickle into the sink. The slow flow of water will prevent the liquid from freezing within the pipes.
