A Guide to Common Water Heater Problems in Mercer Island, WA
Your water heater will often give you warning signs before it fails completely. Here are some common problems our Mercer Island, WA plumbers see, and what they might mean.
- No Hot Water: For a gas water heater, this is often a pilot light that has gone out or a faulty thermocouple. For an electric model, it's frequently a tripped circuit breaker or a failed heating element.
- Not Enough Hot Water: The thermostat may be set too low, or a heating element could be failing. In gas heaters, a malfunctioning gas valve could be the issue. It can also be a sign of sediment buildup in the tank.
- Water is Too Hot or Has a Bad Odor: Water that is too hot usually means the thermostat is set too high. A "rotten egg" smell is typically caused by bacteria in the tank, which can be resolved by flushing the tank and replacing the anode rod.
- Strange Noises (Rumbling or Popping): This is almost always caused by a buildup of sediment at the bottom of the tank. The noise is water trapped under the sediment boiling. This reduces efficiency and can damage the tank over time.
- Water Leaking From the Unit: A leak could be from a loose connection, a faulty pressure relief valve, or, most seriously, a crack in the tank itself. A leaking tank is an emergency and requires immediate replacement.If you are experiencing any of these issues with the water heater in your Mercer Island, WA home, it's best to call a professional plumber from JLK Plumbing for a safe and accurate diagnosis.
