Your Noritz water heater may be making unusual sounds due to a variety of reasons. It could be due to sediment build-up in the tank, which can be fixed by flushing the tank. If the noise is a popping or rumbling sound, it might be due to the water being too hot, which can be resolved by adjusting the temperature. A high-pitched whining noise could indicate a faulty or loose element, which may need tightening or replacement. If you’re unable to identify or fix the issue, it’s best to seek professional help.
