Boiler emits gurgling or trickling water sounds in piping

Safety first: Hot water can scald. Use caution when bleeding air.

Steps:

• Bleed radiators: Open manual air vents until water flows steadily.
• Check automatic air vent: Inspect the automatic air vent near the Peerless boiler. If leaking or not venting, replace it.
• Verify system pressure: Ensure proper fill pressure to help move air to vents.
• Install air separator: If none is present, consider adding a microbubble air separator to improve air removal.
