Most Common Water Heater Problems

Modern water heaters have a long lifetime. Many come with warranties, and you hope they last for years with no trouble. However, there are many reasons behind the malfunctioning of a water heater. Common water heater issues might lead to the appliance failing, providing no warm water, or other issues. It helps if you know how to solve the problem or state it to qualified plumbers in San Jose. Moreover, if you are a DIY person, knowing the most common issues will help you to fix any water heater.

Here Are the Common Water Heater Failures.

1. Foul Smelly Water

Water that smells bad or looks unclean indicates contamination. Bacteria inside the tank cause hot water smells. Experts suggest flushing the tank 1-2 times annually to keep a water heater in good working order. If odors are coming from both the hot and cold water, then the problem might not be originating from the water heater itself. In any scenario, it is better to call a licensed local plumber in San Jose if the smell persists.

2. No Warm Water

If you have an electric water heater, the most common problem would be a warm water shortage caused by a damaged heating element. Two heating elements of your water heater are in charge of heating the incoming water in the storage tank. The malfunctioned heating element will leave you with little to no hot water utilized for showering, cleaning, and washing.

3. Water Heater Leaks

Connections that are too loose could leak, and you should use a wrench to tighten them. They may also originate from valves, which can be changed. Since you may have a rusty tank, it is more hazardous if the leak originates there. You must replace the tank if it has deteriorated. Some of the major causes include:

  • Age
  • Bad installation
  • Poor maintenance
  • Loose drain valve
  • The pressure inside the tank

4. Longer Reheating Duration

It is one of the common electric water heater problems. Different models can differ significantly in how long it takes to heat water. However, if the hot water is taking longer than usual to heat, there may be a problem with the heating elements (including sediment build-up on them) or thermostat, and those components may need to be changed.

5. Low Water Pressure

Your water lines’ diameter will decrease when magnesium and calcium start accumulating. As a result, your sinks or appliances will not receive adequate warm water from the water heater. Additionally, you can verify that your water inlet valve is not partially closed. An average homeowner without a plumbing license cannot repair this water heater issue since changing water pipes involves removing drywall. Consult a certified plumber for water heater repair in San Jose.


Your water heater should be on a regular maintenance checklist whether you own or rent a property. Finding the issue early and taking action to fix it is the most important thing you can do. Ignoring the issue will only worsen it and cost you more money in the long run. Sometimes there is no simple solution, and problems with the hot water tank are simply the result of needing a whole new unit. A skilled installer is suitable for water heater installation in San Jose since installing a new water tank is not a simple task.
