Nothing disrupts comfort faster than stepping into a cold shower when you expected warm, soothing water. A malfunctioning hot water heater can quickly turn your morning routine upside down. At Trusted Plumbing and Heating, we understand how frustrating it can be when your water heater stops working — especially when you rely on it daily for bathing, cleaning, and comfort. This guide dives deep into the most common water heater problems, what causes them, and when it’s time to call a professional plumber for expert help.
Understanding the Basics: How Your Water Heater Works?
Before asking, “Why is my hot water heater not working?”, it helps to know how it functions. Your water heater stores and heats water in a tank (for traditional systems) or heats it on demand (for tankless models). It uses either gas or electric power to maintain the right water temperature through a thermostat. When any part of this process is disrupted — whether it’s the pilot light, heating element, or water supply line — your hot water stops flowing as expected.
At Trusted Plumbing and Heating, our experts often find that understanding these basics helps homeowners identify early warning signs before bigger problems develop.
No Hot Water? Check the Power or Gas Supply
If you have no hot water, the issue could be as simple as a power or gas supply failure. For electric models, check the breaker box — a tripped breaker can stop your heater water from working entirely. For gas systems, verify that the pilot light is on. If the pilot won’t stay lit, you might have a faulty thermocouple or gas control valve.
Trusted Plumbing and Heating recommends always turning off the power or gas before attempting any troubleshooting. If you’re uncomfortable handling electrical or gas components, let our licensed plumbers inspect the water heater safely.
Water Leaking Around the Tank
One of the most common water heater problems homeowners face is water leaking near or under the unit. This can happen due to corroded tanks, loose valves, or a compromised drain water line. Even a small water leak can cause significant damage to your flooring and foundation over time.
Our team at Trusted Plumbing and Heating advises checking connections at the cold water and hot water outlets for signs of moisture. If the leak is coming from the bottom of the tank, it may be time for a replacement or installation of a new unit.
Inconsistent Water Temperature
If your water temperature fluctuates between too hot and too cold, your thermostat or heating element may be failing. Mineral buildup in the tank can also cause uneven heating, especially in areas with hard water. Sediment insulates the heating element, forcing the water heater to work harder and less efficiently.
At Trusted Plumbing and Heating, our experts flush tanks to remove buildup and inspect all components to ensure consistent heating performance.
Strange Noises Coming from the Tank
Rumbling, popping, or banging noises from your tank can sound alarming — and they’re often a sign of sediment buildup. As water heats, trapped air bubbles try to escape through the sediment layer, causing noise. This can strain your water heater and shorten its lifespan.
Regular maintenance from Trusted Plumbing and Heating can prevent this issue. Our services include professional flushing and inspection to keep your system quiet, clean, and efficient.
Water Too Hot or Pressure Too High? Check the Relief Valve
If you notice scalding hot water or unusually high pressure, your pressure relief valve could be malfunctioning. This relief valve is a crucial safety feature designed to release excess water pressure from the tank. When it fails, the pressure inside the water heater can rise dangerously.
Trusted Plumbing and Heating recommends testing your pressure relief valve once or twice a year to ensure it functions correctly. If you’re unsure how to do this safely, our certified plumbers can handle it during a maintenance visit.
Low Hot Water Pressure
If your water pipes or lines are partially clogged with sediment or rust, you’ll likely experience low hot water pressure. This can also happen if your shut-off valve isn’t fully open. Over time, buildup in the pipes can restrict water flow, making showers frustratingly weak.
The skilled team at Trusted Plumbing and Heating can diagnose low-pressure issues quickly — whether it’s a plumbing line blockage or an aging water heater in need of replacement.
Discolored or Rusty Water
If your water looks brownish or rusty, it’s often a sign of corrosion inside your tank or pipes. The anode rod, which prevents rust in your water heater, may have worn out. Replacing it promptly can prevent leaks and maintain the purity of your hot water supply.
At Trusted Plumbing and Heating, we replace worn components and offer corrosion-resistant products to extend your water heater’s life.
When to Call a Professional Plumber
While some minor water heater problems can be handled by homeowners, others require the expertise of a licensed plumber. Issues involving electrical wiring, gas lines, or pressure relief valves should always be managed by professionals.
