The answer to 'water heater installation making noise' is that a noisy water heater can be caused by a few common issues. One of the most frequent causes is sediment buildup at the bottom of the tank. As the sediment heats up, it can cause rumbling or popping sounds. Another possible issue is a malfunctioning heating element, which can also produce unusual noises. In some cases, the water heater's thermostat may be set too high, leading to excess pressure and vibration.
If the noise is mild and the water heater is otherwise functioning properly, you may be able to address the issue yourself by flushing the tank to remove sediment. However, for more severe or persistent noises, it's best to call a professional plumber to diagnose and repair the problem. They can properly inspect the unit, identify the root cause, and make any necessary adjustments or replacements to restore quiet operation.
