When a water heater fails, the best path depends on the age of the unit and the severity of the problem. If your heater is under eight years old and the issue is a simple part—like a burnt-out heating element, a faulty pilot light, or a bad pressure relief valve—a repair is the most economical choice. Aqua Science can typically swap these components in a single visit, saving you the cost of a full system.

However, if your tank is actively leaking from the bottom or the side, it cannot be repaired safely. A leak at the base means the internal steel tank has rusted through, posing a high risk of flooding. If your unit is over 10 years old and showing signs of heavy rust or significant sediment noise, investing in a new, high-efficiency model is often more cost-effective than repeatedly paying for emergency repairs on an appliance that is nearing the end of its life.

The key to preventing an emergency call in Mesa is consistent annual maintenance. Because East Valley water is so mineral-heavy, we recommend flushing your tank once a year. By connecting a hose to the drain valve and clearing out the sandy calcium sludge, you allow the heat source to reach the water directly. This simple step stops the unit from overheating, which protects the glass liner and prevents your electric elements from burning out.

For homeowners with tankless systems, maintenance is even more critical for long-term reliability. These units must be descaled annually with a specialized solution to dissolve the mineral deposits inside the narrow heat exchanger. Skipping this service will lead to restricted water flow, “Error Code” shutdowns, and eventual system failure. Regular preventative care ensures your water heater delivers the energy savings and performance you expect throughout its entire lifespan.
