Your water heater quietly does its job every day, but when was the last time you had it checked or scheduled maintenance for it?
The water heater rarely gets attention until something goes wrong. In Bay Area homes, where hard water is common and energy costs are high, a little extra care can make a big difference.
By focusing on water heater maintenance, you can reduce breakdowns, improve efficiency, and add years to the system’s lifespan.
Get more years out of your water heater with these water heater care tips.
Why Preventive Care Matters
Waiting until you have no hot water is never ideal. A water heater can last a decade or more, but neglect often shortens that timeline.
Luckily, you can take proactive steps to ensure your hot water flows consistently. These small steps can go a long way when you’re trying to extend water heater life:
Flushing sediment
Inspecting parts (whether it’s done by you or a Bay Area plumber)
Scheduling yearly checkups
When you take care of the small things, you save yourself from bigger repairs and costly replacements later.
Flushing the Tank: The Foundation of Longevity
One of the most overlooked but critical steps in proactive water heater maintenance is an annual flush. Over time, sediment from hard water builds up inside the tank. That sediment insulates the water from the burner or heating element, forcing the system to work harder and reducing efficiency.
How Flushing Helps
Draining the tank once a year washes away mineral buildup, helping your water heater heat more effectively and lowering your utility bills. It also prevents sediment from clogging valves or creating hot spots that can damage the tank’s lining.
Why Hard Water Increases the Need
Homes in Pacifica and across the Bay Area often have hard water, which accelerates sediment accumulation and makes flushing even more important here than in regions with softer water.
Inspecting the Anode Rod: The Unsung Hero
Another critical component of preventative care is the anode rod. This metal rod is designed to attract corrosion so that your tank doesn’t rust.
What To Look For
The anode rod should be checked every two to three years. If it’s worn down to less than half an inch thick or coated with calcium, it’s time for replacement. Neglecting this step allows the tank itself to corrode, often leading to leaks and premature failure.
The Cost of Skipping It
A new rod is inexpensive compared to replacing an entire water heater. Regular inspections keep corrosion at bay, helping your system reach its full lifespan.
Testing the Temperature and Pressure Relief Valve
Every water heater has a temperature and pressure relief (T&P) valve, which acts as a safety mechanism. This valve opens if the tank builds up too much pressure, preventing dangerous ruptures.
How To Test Safely
Once a year, gently lift the valve’s lever to ensure water flows out and the valve resets properly. If it doesn’t, or if you notice leaks, the valve should be replaced immediately. Because this test involves handling pressurized hot water, many homeowners prefer leaving it to professionals.
Why It Matters
A faulty T&P valve compromises both safety and efficiency. Including it in your annual maintenance routine adds a layer of protection for your home.
When To Call in a Professional
While some steps, like flushing the tank, can be done without a hitch, other water heater maintenance tasks require expertise and experience. Some of these tasks are:
Checking the anode rod
Ensuring electrical connections are secure
Replacing valves safely
Unless you’re willing to risk a water heater replacement (or a trip to the emergency room), these are best done by licensed plumbers.
A professional checkup also includes looking for hidden issues like gas leaks, electrical wear, or code compliance concerns.
