  4. Let the water run until no more water is flowing through the faucets. This will ensure that all water is drained from the pipes.
  5. Finally, tightly close all the faucets to prevent any water from re-entering the system.

Empty Toilet Tanks

To ensure all water is drained from your pipes, it is important to flush the toilets until the tanks are empty. Here’s how you can do it:

  1. Turn off the water supply to the toilet by closing the shut-off valve, usually located behind the toilet near the floor.
  2. Press and hold the flush handle until the water in the tank is completely emptied.

Remember, this step is crucial as any remaining water in the toilet tanks can freeze and cause damage to the pipes.

  • Turn off the water supply
  • Press and hold the flush handle

Drain Water Heater

Draining your water heater is an essential step in winterizing your pipes. Follow the manufacturer’s instructions on how to drain your specific water heater model.

To drain your water heater, take the following steps:

  1. Turn off the power supply to the water heater.
  2. Connect a hose to the drain valve at the bottom of the unit.
  3. Open the valve and allow the water to flow out until it stops completely.
  4. Once drained, close the drain valve and remove the hose.

Remember to always refer to the manufacturer’s instructions for your water heater model to ensure proper and safe draining.

Tip: Regularly draining your water heater helps remove sediment and prolong its lifespan.

Blow Out Residual Water With Compressed Air

To ensure there is no residual water left in your pipes, compressed air can be used to blow it out. Here are the steps to follow:

  1. Attach an air compressor to the main water supply line, using an adapter if necessary.
  2. Start with the highest faucet in your home and open it.
  3. Allow the compressed air to blow through the pipes, pushing out any remaining water.
  4. Move to each faucet in your home, starting from the upper floors and working your way down.
  5. Open each faucet and let the compressed air blow through the pipes.
  6. Once you no longer hear air escaping, turn off the faucets.
