How do you remove an airlock from a gas geyser?

Removing an airlock from a gas geyser involves releasing trapped air from the gas line or gas valve to allow proper gas flow to the burner and ensure the geyser ignites and operates correctly. Here’s a step-by-step guide to remove an airlock from a gas geyser:

  1. Turn Off Gas Supply: Before attempting to remove an airlock, it’s essential to shut off the gas supply to the geyser for safety reasons. Locate the gas shut-off valve near the geyser and turn it to the “off” position.
  1. Allow Geyser to Ventilate: After turning off the gas supply, allow the gas geyser to ventilate for a few minutes to ensure any built-up gas dissipates and the area is safe to work in.
  1. Locate Gas Valve and Bleed Screw: Next, locate the gas valve on the gas line connected to the geyser. The gas valve is typically located near the gas inlet or burner assembly. Some gas valves have a small bleed screw or bleeder valve designed to release trapped air from the gas line.
  1. Prepare Tools: Prepare the necessary tools for bleeding the gas line, including an appropriate-sized wrench or screwdriver to loosen the bleed screw.
  1. Loosen Bleed Screw: Using the wrench or screwdriver, carefully loosen the bleed screw on the gas valve. Turn the screw counterclockwise to open it slightly. Be cautious not to unscrew the bleed screw completely, as this can result in gas leakage when the gas supply is restored.
  1. Listen for Hissing Sound: As you loosen the bleed screw, listen for a hissing sound indicating trapped air escaping from the gas line. This is a sign that the airlock is being released.
  1. Close Bleed Screw: Once you hear the hissing sound and no more air is escaping, carefully tighten the bleed screw clockwise to seal it. Ensure the screw is snug but not over-tightened to avoid damaging the valve.
  1. Restore Gas Supply: After bleeding the gas line, turn the gas shut-off valve back on to restore the gas supply to the geyser.
  1. Check for Proper Operation: With the gas supply restored, test the geyser to ensure it ignites and operates correctly. Follow the manufacturer’s instructions for lighting the pilot light or igniting the burner, and monitor the geyser for any signs of malfunction.
  1. Monitor for Leaks: After removing the airlock and restoring the gas supply, monitor the geyser and gas line for any signs of gas leaks, such as a hissing sound, smell of gas, or bubbles when applying a soapy water solution to the connections. If you detect a gas leak, shut off the gas supply immediately and contact a professional plumber or gas technician for assistance.

By following these steps, you can effectively remove an airlock from a gas geyser and restore proper gas flow for safe and efficient operation. If you’re unsure how to bleed the gas line or if you encounter any issues, it’s best to consult a qualified plumber or gas technician for assistance to ensure the task is performed safely and correctly.
