How do you remove air pressure from a pipe?

Published in Plumbing Maintenance 2 mins read

To remove air pressure from a pipe, you need to create pathways for the air to escape. A common way to do this is by opening faucets and fixtures throughout your home.

Method for Releasing Air Pressure

The most effective way to release trapped air pressure involves utilizing your home's plumbing system. Here’s a step-by-step guide, incorporating the advice from the reference:

  1. Open Faucets and Fixtures:

    • Turn on all faucets (both hot and cold) about halfway. This allows air to escape the lines.
    • Include all sinks, tubs, and shower faucets.
    • Don't forget outdoor hose bibs as these also can contain air.
  2. Flush Toilets:

    • Flush all toilets once. This helps release any air in the toilet water supply lines.
  3. Run Water Appliances:

    • Run a short cycle on both your dishwasher and washing machine. This draws water, and any trapped air with it, through their lines.

Detailed Steps:

  • Start at the Highest Point: Begin by opening faucets on the highest floors of your house, as air tends to rise.
  • Systematic Opening: Methodically work your way down to the lowest level of your house, opening all fixtures along the way.
  • Observe Water Flow: Watch for consistent water flow at each fixture. You may notice sputtering or air hissing when air is escaping, which is normal during the process.
  • Complete Cycle: Let the water run for a few minutes at each fixture. This allows enough time for the air to escape.
  • Repeat if Necessary: If the problem persists, repeat these steps. It may take multiple cycles to remove all the air from the plumbing system.

By following these steps, you are creating an escape route for the trapped air, allowing the water pressure to return to normal. This method is based on the principle of allowing air to escape through the open outlets of your plumbing system. The water pressure will help to push the air out of the pipes.
