Key maintenance tasks for a commercial water heater include regular inspection of the heating elements, checking for leaks in the tank and connections, flushing the tank to remove sediment buildup, testing the pressure relief valve, and ensuring proper ventilation for gas-powered units. Regular maintenance helps to ensure longevity and efficiency of the water heater.

Hydro jetting is more effective at removing stubborn clogs, mineral deposits, and debris from drains compared to traditional drain cleaning methods. It also helps prevent future clogs by thoroughly cleaning the pipes and restoring proper water flow. Additionally, hydro jetting is environmentally friendly as it uses high-pressure water instead of harsh chemicals.

Some DIY maintenance tips to prevent frequent water heater repairs include flushing the tank annually to remove sediment buildup, checking and replacing the anode rod as needed, testing the pressure relief valve, and inspecting for leaks or corrosion regularly.
