Hearing loud rumbling, popping, or banging noises from your water heater immediately after taking a long shower is typically caused by thermal recovery and heavy sediment agitation. When a large volume of hot water is drawn out during your shower, the tank fills with cold water, triggering the burners or heating elements to fire up and run continuously. If sediment has accumulated at the bottom of the tank, the rapid heating cycle causes trapped water beneath the sediment to boil furiously, producing loud noise. Verification: Flush sediment from the tank base to eliminate post-shower boiling noises.
