The answer to 'why is my water heater' is that there are several common causes for water heater issues, including sediment buildup, thermostat problems, leaks, and age-related wear and tear. Symptoms may include inconsistent water temperature, strange noises, and water pooling around the unit.
If you're experiencing problems with your water heater, it's important to diagnose the issue and determine whether it's a simple DIY fix or requires professional plumbing services. Some minor issues like flushing the tank or adjusting the thermostat can often be handled by a handy homeowner, but more complex problems like leaks or faulty heating elements usually necessitate calling in a licensed plumber.
