How To Winterize A House With Antifreeze?

November 4, 2022 by Andrew Leave a Comment

Winterize A House ||Propylene glycol antifreeze is commonly used to winterize the plumbing in a house. It is specifically designed for use in potable water systems and is considered safer than ethylene glycol antifreeze, which is toxic. Propylene glycol antifreeze is also sometimes referred to as “plumbing antifreeze” or “RV antifreeze.”

When purchasing antifreeze for winterizing your house, make sure to choose a product that is explicitly labeled for use in potable water systems. This ensures that it is safe for contact with your plumbing and the water supply.

Propylene glycol antifreeze has a lower toxicity compared to ethylene glycol antifreeze, making it a safer option for residential use. It provides protection against freezing by lowering the freezing point of water in your plumbing system, helping to prevent pipes from bursting and other related damage during cold weather.

Always follow the manufacturer’s instructions for the specific propylene glycol antifreeze product you choose to ensure proper usage, dilution ratios, and other safety considerations. If you have any doubts or questions, it is advisable to consult a professional plumber for guidance on the appropriate antifreeze to use and how to properly winterize your plumbing system.

To use propylene glycol antifreeze to winterize the plumbing in your house, follow these detailed steps:

  1. Gather the necessary materials: You will need propylene glycol antifreeze labeled for potable water systems, a bucket or container, a pump (optional), and a wrench or pliers.
  2. Turn off the water supply: Locate the main water supply valve to your house and shut it off. This will prevent water from flowing into your plumbing system during the winterizing process.
  3. Drain the water from the plumbing system: Starting from the highest point in your house, open all faucets, including both hot and cold water taps, and flush all toilets. This allows water to drain from the plumbing system.
  4. Drain the water heater: If you have a water heater, turn off the power or gas supply to it. Connect a hose to the drain valve at the bottom of the water heater and place the other end in a suitable drainage area, such as a floor drain or outside. Open the drain valve to allow the water heater to drain completely.
  5. Prepare the propylene glycol mixture: Follow the manufacturer’s instructions on the antifreeze container for the appropriate dilution ratio. Typically, a 50/50 mixture of propylene glycol antifreeze and water is recommended. Mix the antifreeze and water in a clean bucket or container.
  6. Add the antifreeze to the plumbing system: Starting from the lowest point in your house, use a wrench or pliers to remove the drain plug from each plumbing fixture, such as sinks, showers, and bathtubs. Insert a funnel into the drain opening and pour the propylene glycol mixture into the plumbing system until it starts coming out of the fixture. Replace the drain plugs.
  7. Repeat the process for each fixture: Move to each fixture in your house and repeat the process of removing the drain plug, pouring in the antifreeze mixture until it flows out, and replacing the drain plug.
  8. Flush toilets with antifreeze: Pour some propylene glycol antifreeze directly into each toilet bowl and flush it to allow the mixture to flow into the toilet’s plumbing.
  9. Consider using a pump (optional): If you have a large or complex plumbing system, you may use a pump to circulate the antifreeze mixture throughout the pipes. Consult a professional plumber for guidance on using a pump effectively and safely.
  10. Inspect for any missed areas: Once you have treated all the plumbing fixtures, double-check to ensure that you have properly winterized all areas of your plumbing system. Make sure all drain plugs are securely in place.
  11. Turn off power to appliances: If you have any appliances connected to your plumbing system, such as a dishwasher or washing machine, turn off their power supply and follow the manufacturer’s instructions for winterizing those appliances.
  12. Reopen the main water supply valve: After you have completed the winterizing process and ensured that antifreeze is distributed throughout the plumbing system, you can reopen the main water supply valve to your house. This allows the antifreeze mixture to mix with any remaining water and provides protection against freezing.

Remember, when spring arrives, you will need to flush out the antifreeze from your plumbing system before using it again. Follow the manufacturer’s instructions for proper flushing procedures or consult a professional plumber to ensure a safe and thorough process.

It’s worth noting that these steps provide a general guideline, but specific procedures and considerations may vary based on your plumbing system, local regulations, and manufacturer recommendations. If you are unsure or uncomfortable with the process, it is advisable to consult a professional plumber for assistance.

Precautions while using antifreeze to winterize a home

  1. Use antifreeze labeled for potable water systems: Ensure that the antifreeze you use is specifically designed and labeled for use in potable water systems. This ensures it is safe for contact with your plumbing and the water supply.
  2. Follow manufacturer’s instructions: Read and follow the manufacturer’s instructions and guidelines provided with the antifreeze product. This includes information on proper usage, dilution ratios, and safety precautions.
  3. Wear protective gear: When handling antifreeze, especially during the mixing and pouring process, it’s advisable to wear appropriate protective gear, such as gloves and safety goggles, to protect your skin and eyes.
  4. Avoid ingestion and skin contact: Antifreeze contains chemicals that can be harmful if ingested or come into contact with your skin. Keep it out of reach of children and pets. If accidental ingestion or contact occurs, seek medical attention immediately.
  5. Properly ventilate the area: When working with antifreeze, ensure that the area is well-ventilated to minimize exposure to fumes. Open windows or use fans to circulate fresh air.
  6. Dispose of antifreeze properly: Follow local regulations for the proper disposal of antifreeze. It should not be poured down drains, onto the ground, or into storm sewers. Check with your local waste management facility for guidance on how to dispose of antifreeze safely.
  7. Flushing before use: Before using your plumbing system again in the spring, it’s crucial to thoroughly flush out the antifreeze from the system. Follow the manufacturer’s instructions or consult a professional plumber to ensure a proper and safe flushing process.
  8. Consider professional assistance: If you are unsure about the process or have concerns, it is advisable to consult a professional plumber who can provide guidance and ensure the winterizing process is carried out correctly.

By taking these precautions, you can help ensure your safety and the proper winterization of your home’s plumbing system. Always prioritize safety and follow the manufacturer’s instructions and any local regulations. Read More>>
