When you're about to jump in the shower, the last thing you want is for the water to be ice-cold. Unfortunately, water heaters sometimes run into trouble. The good news is that either you or a plumbing professional can easily fix most of the common problems.
Unlit Pilot Light
Gas water heaters use a controlled flame to heat the water. As with a furnace or fireplace, if the pilot light goes out, the water won't heat. If the pilot light can't be lit, there may be a problem withthe gas line.
If your water runs warm but not hot, or filling your tub ends up with a lukewarm bath, the thermostat on your water heater may be set too low. 120 degrees Fahrenheit is the recommended temperature for most residences, as any hotter can risk scalds and burns.
Sediments from the water and pipes collecting in a water heater tank can cause unpleasant odors due to the materials burning, and reduces the amount of available hot water. Flushing out the tank to clear the sediment will fix these issues.
While some of the common water heater issues can be fixed by a homeowner, bigger problems require professional maintenance. Check out this link for more about water heater repair in Chapel Hill.
