Cold temperatures can cause water pipes to freeze. The best prevention against frozen pipes is to keep them warm enough to stay above the freezing point.
Tip #1: Keep the Heat On!
This should provide enough heat to keep the pipes warm and to prevent any water inside from freezing. If you or your tenants are leaving for a long period of time, make sure that the heat is kept on in your property.
Tip #2: Keep Interior Doors Open.
More often than not, pipes are often located in cabinets. When the temperature drops, it is a good idea to keep these cabinet doors open so that the heat from the rest of the house can then circulate to the cabinets to keep the pipes warm as well.
Tip #3: Allow the Faucet to Drip.
Allowing the faucet to be open will prevent pressure from building up and thus keep the pipe from bursting. Water is much, much more likely to freeze when it’s stationary, rather than mobile, so enabling a bit of a gradual flow can make a big difference for your system.
Tip #4: Apply Heating Tape.
Heating tape works like an electric blanket for pipes. This can be a good solution for short sections of pipe that are easily accessible but have a high risk for freezing.
Tip #5: Seal Up Cracks and Holes.
Seal gaps around holes where pipes run through walls or floors, especially where the hole is letting in cold air.
Tip #6: Add Extra Insulation.
Pipes that are located in areas such as basements or attics, may need extra insulation to keep from freezing. Additional insulation can also be added to walls and ceilings to keep the pipes warm.
