Winterizing Tips for Vacant Houses: Clarity on Depressurizing and Water Heater Maintenance
When preparing a vacant house for winter, ensuring that your plumbing system is winterized correctly is crucial to prevent damage from freezing temperatures. This article provides clear guidance on whether you should depressurize water supply pipes, leave them full of water, or turn on your electric water heater, along with recommended safety measures.
Understanding the Risks: Frozen Pipes and Water Heater Issues
When dealing with vacant houses in winter, the top priority is to prevent water from freezing in pipes, which can cause them to burst. Similarly, overheating an electric water heater while away can lead to damage due to a lack of water. Here, we delve into these issues and provide recommendations for safe and effective winterizing practices.
Risk of Leaving Water Supply Pipes Full and Water Heater On
Leaving a house vacant in winter with the water supply pipes full and the electric water heater turned on poses several risks:
Water Heater Running Dry: If the water heater runs out of water due to a leak, it can overheat and cause damage. Risk of Electrical Hazards: If the unit does not shut off properly, it can lead to electrical surges and other hazards. Freezing Issues: The water inside the heater may freeze, leading to damage to the equipment. Thermostat Settings: Maintaining the house at a higher temperature can also be risky, as it may increase energy costs and potential fire hazards.It is generally not recommended to leave the water supply pipes full and the water heater on when away.
Safe Winterizing Methods
Here are some safe and practical methods to winterize a vacant house:
Drain the Water System
One of the safest methods to protect your plumbing system is to completely drain the water supply pipes and water heater. This step-by-step process involves:
Turn off the main water supply valve. Open all faucets to drain the remaining water from the pipes. Flush out the water heater. Turn on the water supply, flush the heater until the water runs clear, then drain again. Use compressed air to blow out any remaining water from the lines.Turn Off the Water Heater
To further ensure safety, it is safest to turn off the electric water heater before leaving:
Disconnect the power supply to the water heater at the circuit breaker or fuse panel. Follow the manufacturer's instructions for complete shutdown procedures, which may include draining the unit.Remember to keep the property's thermostat set to a minimum temperature that prevents freezing, typically above 55°F or 13°C, while ensuring the house is heated sufficiently to prevent unnecessary costs and risks.
Winterizing Additional Measures
While draining and turning off the water heater are key steps, additional winterizing measures can further protect your property:
Insulate exposed pipes to prevent freezing. Ensure the house is properly sealed to keep cold air out. Inform your insurance company about the vacant property. Arrange for a neighbor or trusted friend to periodically check on the house, addressing any potential issues promptly.These recommendations can vary based on your specific circumstances, the climate in your area, and any local regulations or recommendations.
Conclusion
In conclusion, the best winterizing practice is to either completely drain the pipes and water heater or maintain a warm environment with the water supply and heater off. This approach ensures safety and minimizes the risk of damage to your plumbing system. Always consult with professionals or experts for advice specific to your situation and location.
