Plumbing system becomes vulnerable during winter season. This is because pipes don’t burst at the point where water freezes, but somewhere between freeze and a closed faucet, such as washing machine or kitchen faucet. When pressure builds up due to ice blockage, it normally has nowhere to go but through the pipe walls leading to bigger damage. Plumbing winterization usually helps to stop frozen pipes before they happen and also prevent expensive water damage.
Open faucets and drain waterlines. Outdoor plumbing such as above ground hose faucets need to be winterized. It is important to make sure that you winterize the hose faucets on the outside of your home. This simply means turning water off, opening up the valve so that all the water drains out of it. You should leave the valve open for the duration of the winter so that the remaining water may drain out. If you don’t winterize the hose faucets, it is likely that the pipe will burst if the water inside freezes because water expands as it freezes.
Pipe insulation to freezing pipes. Insulating the pipes helps keep them from getting too cold and also help to prevent them from freezing. It provides first defense against cold temperatures and frozen pipes. When you winterize the pipes, you should add a thick layer of insulation around the pipes and make sure you clean the pipes thoroughly before wrapping them in insulation. Also, the pipe should be completely covered with insulation and it is attached securely.
Drain the water heater. It is important to turn off the power if you have an electric water heater. If you have a gas heater turn off the thermostat. You need to close the cold water supply valve that is located at the top of water heater. This keeps the water that flow into the tank while its draining.
Crawlspace. If your house has crawlspace, it is important to shut the crawlspace vents. You should cover your vents with heavy pieces of cardboard that would fit the vent. Make sure that any doors or covers on the opening of the crawlspace are sealed tightly. Having insulation on the vents would be helpful as any wind that goes into the crawlspace can get onto the pipes causing them to freeze.
If you have an outdoor sink, it also needs to be winterized so as to prevent water freezing and bursting the fixture. Winter weathers can be harsh and also damaging. You need to take the necessary steps so as to protect your property.
