Step 1: Turn off the water supply and drain the water lines
The first and most crucial step in winterizing your plumbing in a vacant house is to shut off the main water valve and drain the water lines. This will prevent water from sitting stagnant in the system, reducing the risk of freezing and subsequent damage.
To begin, locate the main water valve in your house. This valve is usually found near the water meter or where the main water supply enters your property. Turn the valve clockwise to shut off the water supply to the entire house. This will stop any water from flowing into the plumbing system.
Once the water supply is turned off, it’s time to drain the water lines. Start by opening all the faucets, including the ones in the kitchen, bathrooms, and outdoor spigots. Opening the faucets will relieve the pressure in the pipes and allow the water to flow out.
Next, locate the lowest faucet in your house, usually in the basement or the ground floor. This will be the primary point for draining the water lines. Open this faucet and let the water drain out completely. Keep the faucets open until no more water comes out.
In addition to faucets, don’t forget to drain other fixtures that hold water, such as toilets, showers, and washing machines. Flush the toilets and run the showers to empty the tanks and drain the remaining water.
After draining all the fixtures and faucets, it’s a good idea to leave them open to allow any residual water to evaporate. This helps to further reduce the risk of freezing and ensures a dry plumbing system.
By turning off the water supply and draining the water lines, you take the first critical step in winterizing the plumbing in your vacant house. This prevents any water from remaining in the system and eliminates the potential for freeze-related damage. Now let’s move on to the next step to further protect your plumbing system.
Step 2: Drain the plumbing fixtures and remove water from traps and pipes
After turning off the water supply and draining the water lines, the next step in winterizing your plumbing in a vacant house is to empty and disconnect all toilets, sinks, and faucets, and remove any remaining water from the traps and pipes.
Start by emptying the toilets in your house. Flush the toilets multiple times to remove as much water as possible from the tanks and bowls. Consider using a plunger to force out any remaining water in the bowl. Once the toilets are empty, you can place a small amount of antifreeze in the bowl to prevent any residual water from freezing.
Next, turn off the water supply to the sinks and faucets. Underneath the sink, there are usually shut-off valves that control the water flow. Turn these valves to the closed position to cut off the water supply to the fixtures.
Once the water supply is turned off, open the faucets to drain any remaining water. Run both the hot and cold water faucets until the water stops flowing. This will ensure that all the water is emptied from the supply lines.
In addition to emptying the fixtures, it is crucial to remove any water from the traps and pipes. Traps are the curved sections of pipe located beneath sinks and tubs. They hold water to prevent sewer gases from entering your home. To remove the water from the traps, place a bucket or container under the trap and unscrew the slip nuts with a wrench. Allow the water to drain into the bucket, and then reassemble the trap.
After emptying the traps, proceed to drain the remaining pipes. Start by opening the lowest faucet in your house, similar to the previous step. Once the faucet is open, go through your house and open each faucet for a short time. This will drain any remaining water from the pipes and minimize the risk of freezing.
By emptying and disconnecting all toilets, sinks, and faucets, and removing any water from the traps and pipes, you effectively eliminate water from the fixtures and plumbing system. This helps to prevent freezing and potential damage during the winter months.

Start by thoroughly inspecting your house for any gaps or cracks in the walls, floors, ceilings, or foundation. Common areas where cold air can seep in include around windows and doors, electrical outlets, plumbing penetrations, and utility access points.
Using a flashlight, carefully examine these areas to identify any potential openings. Pay attention to areas where different building materials come together, as they are prone to developing small gaps over time.
Once you have identified the openings, it’s time to seal them. Use caulk to fill in small cracks and gaps in walls and baseboards. Apply a generous amount of caulk and smooth it out with a caulk gun or your finger. Make sure to use a caulk suitable for the material you are sealing to ensure maximum effectiveness.
For larger openings around windows and doors, consider using weatherstripping. Weatherstripping helps to create a tight seal and prevent drafts from entering your home. There are various types of weatherstripping available, including adhesive strips, door sweeps, and window gaskets. Choose the appropriate weatherstripping for each specific area and carefully install it according to the manufacturer’s instructions.
Don’t forget to seal any openings where plumbing penetrations exist, such as where pipes enter the house or utility access points. Use expanding foam insulation or caulk to seal these areas, creating a barrier against cold air infiltration.
