Anode Rod Replacement

At the heart of maintaining your water heater’s lifespan is the regular inspection and replacement of the sacrificial anode rod. This metal rod, made from either aluminum or magnesium, is designed to corrode first, protecting the steel tank from the ravages of rust and corrosion.

Over time, the anode rod will gradually degrade, sacrificing itself to preserve the tank. Typically, the anode rod should be inspected every 3-5 years and replaced when it has depleted to less than half its original size. Neglecting to replace the anode rod can lead to premature tank failure and costly water heater replacement.

Sediment Flushing and Cleaning

Another essential maintenance task is regularly flushing the water heater tank to remove any accumulated sediment. Over time, minerals and other particles can build up in the tank, reducing efficiency, restricting water flow, and even leading to premature tank failure.

By draining the tank and flushing out the sediment, you can help maintain optimal performance and extend the life of your water heater. This process should be carried out annually or as recommended by the manufacturer.

Pressure Relief Valve Testing

The pressure relief valve is a critical safety feature on your water heater, designed to release excess pressure and prevent dangerous tank explosions. Regularly testing this valve by lifting the lever and ensuring it releases water into the drainpipe is an essential maintenance task.

If the pressure relief valve fails to operate properly, it should be replaced immediately to double-check that the continued safe operation of your water heater.

Plumbing Techniques

Pipe Materials and Fittings

The plumbing components that connect your water heater to the rest of your home’s water system play a crucial role in its overall performance and longevity.
