Mountlake Terrace’s Water Heater Service
It’s obvious when you no longer have hot water that your water heater needs attention. However, there are often signs before your water runs cold that your hot water system needs repairing. Some obvious signs are leaks around the system, discolored water, or losing hot water too quickly.
Here are additional signs that indicate that your water heater needs to be serviced.
- Strange sounds coming from the heater
- Water only gets warm
- Corrosion around tanks or pipes
- Low water pressure
Even if the problem seems minor, it could be an indication of a significant issue. Often, if there is one problem with your water heater, then there may be others that you have missed. For example, if you’ve noticed discolored water or low water pressure, there is a chance that corrosion is present. Issues like this can be easy to miss, which is where an experienced professional can help. An expert plumber, like those at Brennan Heating & Air Conditioning, will know exactly where to look.
If any of these problems happen with regularity, you should contact a professional to come and inspect your system. Often the fix will be easy, like replacing a heating element or cleaning the drain line or tank. However, other times, the problem may require water lines or gas lines to be replaced. You may even need a new water heater. The longer you wait to have your water heater inspected, the worse the problem will likely get.
