Strange noises coming from your hot water cylinder are often a sign of underlying issues such as sediment buildup, air pockets, or pressure problems. At Plumbers 365 our plumbing experts regularly inspect and resolve these problems for homeowners across the UK. Some of the common problems which our experts encounter are: 

• Kettling (boiling or rumbling sounds): Caused by limescale and sediment settling at the bottom of the tank.
• Banging or knocking: Likely due to loose pipework or sudden pressure fluctuations.
• Hissing or whistling: Often related to overheating or faulty pressure valves.
• Gurgling or bubbling: Usually a result of air trapped in the system or blocked vent pipes.

Plumbers can flush out the cylinder and inspect valves and thermostats to resolve the issue.
