Your water heater works quietly in the background, delivering hot water for showers, dishwashing, laundry, and more. But like any mechanical system, it can develop problems. Knowing the common water heater issues and how to handle them can save you from cold showers, property damage, or costly replacements. ABV Plumbing provides water heater installation, repair, and maintenance services to help you avoid the worst.
What’s causing your water heater issues and malfunctions?
The root causes of water heater issues are often similar across many homes. Sediment buildup is a frequent culprit: minerals settle at the bottom of the tank, insulating the heating elements and causing inefficiency or uneven heating. Another typical cause is corrosion, which eats away internal components, including the tank itself or plumbing connections. Faulty thermostats and heating elements wear out over time. Pressure relief valves, connections, or overflow lines may develop leaks. Finally, electrical problems or damaged wiring can prevent the unit from heating at all. Recognizing these patterns helps you diagnose and decide when to call a water heater plumber.
Installation of water heater: What you need to know
When planning for the installation of a water heater, several requirements must be met to ensure safe and efficient performance. First, the location should allow adequate clearance around the unit for maintenance and ventilation. It should also have proper structural support and drainage in case of leaks. Electrical or gas supply lines must comply with local code, and sometimes panel upgrades are required. A licensed professional installer ensures that all local building codes are met, safety devices are properly installed, and the unit is sized correctly for the home, a step that ABV Plumbing always includes in our installations.
Signs you should call a water heater plumber immediately
Some issues are more serious and require prompt attention from a water heater plumber. If you see leaking water around the base or from the water heater leaking from the overflow pipe, that indicates either excess pressure or a failing part. No hot water, scalding temperatures, or frequent on/off cycling are red flags. Strange noises like banging, popping, or rumbling often signal sediment or internal damage. If gas units emit smells or you detect corrosion on the tank walls, those are urgent safety concerns. Ignoring these symptoms can lead to flooding, property damage, or system failure.
How to fix water heater leaking from overflow pipe?
Water leaking from the overflow (or T&P) pipe is often due to excessive pressure or temperature. First, check the temperature setting: if it’s set too high, lower it to around 120 °F (49 °C) and monitor. If pressure is high, the pressure relief valve may malfunction. Turn off power or gas and cold-water supply, relieve pressure, and test or replace the relief valve. If the valve is good but the leak continues, it may indicate a deeper problem within the tank.
Under that umbrella, three specific sub-issues often arise:
Fixing thermostat and heating element issues
If your heater gets overheated, the thermostat may be inaccurately calibrated or broken. Shut off the power, remove the access panel, and test the thermostat with a multimeter. Replace it if it fails or is off by a large margin. Similarly, a heating element that no longer regulates properly can overheat the water, triggering overflow dripping. Test and replace bad element(s) with correct specs.
Replacing a damaged heating element
In an electric heater, a heating element can burn out or corrode. To replace it, turn off power and water, drain the tank to a lower water level below the element, remove the old element, clean the mounting surface, and install a new one with a proper gasket. Refill, check for leaks, and restore power. A proper water heater plumber, like ABV Plumbing, can do it quickly and safely if you’re not comfortable doing it yourself.
Addressing unusual noises in the water heater
Noise such as popping, rumbling, or hammering often arises from sediment layering inside the tank. As heat passes through, steam bubbles form and burst beneath the scale, causing pressure and noise. The solution is to drain and flush the tank, removing accumulated deposits. In more severe cases, replacing elements, checking wiring, or even installing a new tank may be necessary.
