Water pipe insulation is important because in the summer or during hot weather cold water pipes form condensation and the water from the condensation will drip. This condensation is called sweating. Dripping water inside of walls, under floors, in ceilings and in dark areas without adequate air flow can cause water damage and mold. Mold growth is dangerous to your health and the health of your house. During the cold winter months water pipes that are not insulated lose heat. Heat loss will cause your hot water heater to work harder which can lead to an early demise. Water pipe insulation will also protect your pipes from freezing if they should be exposed to cold temperatures. Water pipe insulation will also help to lower the cost of heating bills by not using your hot water heater as much. The best way to stop both pipe sweating and loss of heat is to insulate your water pipes. Begin the water pipe insulation process with exposed pipes such as those you can see in your basement, crawl space, attic, garage and other areas that you will have easy access to.

Measure your water pipes. measure both the diameter of your water pipes and the length of your water pipes.

Wipe your water pipes down with a damp rag to remove any dirt, dust and debris.

Buy insulation made especially for water pipes. This type of water pipe insulation is usually made of foam and is available at hardware stores, home improvement stores and plumbing supply stores. It is relatively inexpensive.

Measure the water pipe insulation to the same length as your water pipe.

Cut the water pipe insulation with a small saw or utility knife. Measure and cut insulation for one pipe at a time. Leave the length of pipe insulation as long as possible.

Open the insulation and place it over your water pipe. water pipe insulation will have a straight cut running the length. Do not make other cuts to the length.

Cut water pipe insulation at a 45° angle for elbows or turns in your water pipes.

Secure the water pipe insulation in place with duct tape. Secure the water pipe insulation at any points where two pieces of pipe insulation meet and approximately every 12 to 18 inches.

Wherever you expose any pipes in walls, in ceilings or under floors use the opportunity to insulate them.
