Frequently Asked Questions About Water Heaters

Many people aren’t aware of how water heaters operate, making it hard for them to know when it’s time to call for professional water heater repair in Northridge, CA. This also keeps them from making the most of their investment. 


At Roberts Plumbing Hydro Jet & Rooter, we often receive several questions about water heaters. We compile them along with our answers to help you make sound decisions.

WHY DOES THE WATER HEATER RUN OUT OF HOT WATER?

There are many reasons your water heater runs out of hot water. Perhaps there is too much hot water demand at once, or there could be sediment buildup at the bottom of the water tank. It’s also possible that you got the wrong size for your water heater. Have a professional assess your unit and determine if you need a new water heater installation.

WHY DOES MY WATER HEATER LEAK?

Leaks on your water heater are a serious cause for concern and should be addressed as soon as possible. While some problems are small and only require a simple fix, other issues are big enough to require a water heater replacement. Some of the culprits behind water heater leaks are broken drain valves, faulty temperature and pressure valves, loose water line connections, and corrosion.

WHAT’S THE BEST WAY TO CONSERVE HOT WATER?

You can conserve hot water by installing low-flow faucets and showerheads in your home. Taking shorter showers will also reduce your hot water usage.


If you have a traditional water heater, be sure to have the tank and pipes insulated by your plumber in Northridge, CA. Also, flush the tank every year to eliminate sediment buildup. These preemptive measures not only make your water heater more efficient but also help you save on heating costs.

WHAT TEMPERATURE SHOULD I SET MY WATER HEATER AT EACH DAY?

Most manufacturers recommend setting the tank-type or tankless water heater at 120 degrees. If you own an older model that doesn’t show the temperatures, you can set it to a medium setting to get enough hot water throughout the home.
