Published in Plumbing Maintenance 2 mins read

Bleeding a water system involves removing trapped air to ensure efficient water flow. Here's a general guide:

While the provided reference only covers one aspect of bleeding a water system (turning on the water main), a complete process typically involves the following steps:

Steps to Bleed Your Water System

Here's a table summarizing how to bleed a water system. Note that this is a general guide, and specific procedures may vary depending on your plumbing system.

Step Description
1. Identify Air-locked Fixtures Determine which faucets or appliances are sputtering or not producing a steady water stream.
2. Turn Off the Water Main Locate and shut off the main water supply valve. This prevents more air from entering the system while bleeding.
3. Open the Highest Faucet Open the highest faucet in your home. This allows air to escape as water is reintroduced.
4. Open Other Faucets Open all other faucets in your home, both hot and cold, to allow air to escape from the entire system.
5. Turn On the Water Main Resupply the water by turning the main water valve back on and letting it run for ten to fifteen minutes.
6. Check Toilets Refill toilets and flush them to ensure proper water flow.
7. Close Faucets Starting from the highest point in the house, close each faucet one at a time.
8. Check Water Flow Monitor the water flow at each faucet to ensure a steady stream without sputtering. Repeat if necessary.

Troubleshooting

  • Persistent Air: If air persists, check for leaks in your plumbing system, which may be drawing in air.
  • Low Water Pressure: After bleeding, low water pressure could indicate a blockage or other plumbing issue.
  • Noisy Pipes: Gurgling or banging pipes can sometimes indicate trapped air; repeat the bleeding process.

By following these steps, you should be able to effectively bleed the air from your water system and restore normal water flow.
