Popping and rumbling
Sediment on the bottom of the tank traps water that boils and pops as it escapes. It's the most common water heater noise in Missouri because of hard water. A professional flush usually solves it; heavy build-up may mean the tank is nearing the end of its life.
Hissing, sizzling and banging
Hissing can be a leak hitting the burner or an electric element coated in scale. Banging pipes (water hammer) happen when valves close quickly — arrestors fix it. Screeching usually points to a partially closed inlet valve.
Repair or replace?
A noisy heater under 8–10 years old is usually worth servicing. If it's older, leaking, or producing rusty water, replacement — possibly with a tankless unit — is the smarter investment.
