Signs Your Water Heater Needs Service

A reliable water heater is easy to ignore—until it isn’t. Catching problems early can prevent cold showers, water damage, and an emergency replacement.

Warning signs to watch for

• Water takes longer to heat, or runs out faster than usual
• Popping, rumbling, or knocking sounds from the tank
• Water looks cloudy or has a metallic taste
• Moisture, rust, or pooling around the base of the unit
• The pilot light or ignition system fails repeatedly

Why these symptoms matter

Sediment buildup, worn heating elements, and aging anode rods are common causes. Left alone, they can shorten the life of the unit and raise energy costs.

What to do next

If you notice more than one of these signs, schedule an inspection. A technician can flush the tank, check the thermostat and valves, and tell you whether a repair or replacement is the smarter long-term choice.

Tip: Annual maintenance is one of the simplest ways to extend water heater life—especially in hard-water areas around Castroville and Greater San Antonio.
