The #1 reason water heaters fail early? Skipped maintenance.
Peninsula water heaters take a quiet beating year after year
Every gallon that flows through your water heater carries trace minerals and sediment. Over months and years, that material settles at the bottom of the tank, coats heating elements, and slowly corrodes internal components. Meanwhile, the anode rod (the metal rod that protects the tank from rust) gradually wears away. Without regular maintenance, what starts as a minor efficiency dip turns into higher energy bills, unreliable hot water, and eventually a premature tank failure that could have been avoided.
Professional maintenance once per year covers everything your water heater needs
A proper annual service isn’t just a quick look at the unit. Our technicians work through a complete checklist designed to keep every type of water heater performing at its best.
One visit a year is all it takes
Annual professional maintenance is the single best thing you can do to extend the life of your water heater and keep it running efficiently. It takes about 60 to 90 minutes, and it pays for itself many times over by preventing breakdowns, emergency calls, and early replacements.
Water Heater Field Report
Hard Water Scale, Flushed Out in a Single Visit
Mineral scale bakes onto the copper heat exchanger inside a tankless water heater, costing 16% to 24% of water heating efficiency in hard water long before it starts cracking the exchanger itself, which is why most manufacturers make a yearly flush a warranty requirement rather than a suggestion. Our technician, Cristian, started with a general inspection of the unit and every attached valve and fitting, shut down the gas and electric supply, and closed the built-in isolation valves to cut the heater off from the rest of the home’s plumbing. He connected high-pressure hoses to a submersible pump and circulated a certified, food-grade descaling solution through the heat exchanger for just under an hour. He also checked incoming water pressure, the emergency shut-off valve, and nearby fixtures, so the homeowner finished the call with a documented baseline of their plumbing. Full heat transfer and water pressure were restored, all on one visit.
What to expect before, during, and after water heater maintenance
Before
A Caccia technician will arrive at your Bay Area home and start by identifying your water heater type, age, and overall condition. We’ll ask about any concerns you’ve noticed, like changes in water temperature, unusual sounds, or anything else out of the ordinary, before beginning the service.
During
Our technician works through a comprehensive checklist tailored to your water heater type. For tankless units, we descale the heat exchanger and check ignition and flow sensors.
After
Once the service is complete, we will let you know how everything looks. If we spot anything that needs attention, like a worn anode rod, a slow leak, or a component showing early signs of failure, we’ll flag it and explain your options. We also recommend when to schedule your next maintenance visit so you stay on track.
