Professional Water Heater Maintenance in Houston

Your water heater is one of the hardest-working appliances in your home, yet it is often ignored until something goes wrong. A little maintenance once a year helps it heat efficiently, avoid breakdowns, and reach the full end of its life.

Nick's Plumbing & Air Conditioning has provided water heater maintenance in Houston since 1979. Our service is quick and clean, and it covers tank and tankless, gas and electric water heaters.

Nick's Plumbing explains why annual water heater maintenance matters for Houston homes.

Why Water Heater Maintenance Matters in Houston

Houston's hard water carries calcium and magnesium that settle to the bottom of the tank as sediment. That layer sits between the burner or element and the water, so the heater has to work harder, in some cases up to 30% harder, to heat the same amount of water. Sediment also causes popping and rumbling noises, can clog the drain valve, and speeds up wear on the tank.

Maintenance also matters for insurance. Water heater leaks are one of the most common causes of home water damage claims, and some insurers may question or deny a claim if there is no record of maintenance. A written service record gives you documentation.

What Our Water Heater Maintenance Includes

• Drain and flush - We drain the tank and flush out sediment
• Burner or element check - We clean and inspect the gas burner or test the electric elements
• Air intake and venting - We clear the combustion air intake and check the vent on gas units
• Relief valve test - We test the temperature and pressure relief valve
• Anode rod check - We check the anode rod that protects the tank from corrosion where accessible
• Connections - We inspect fittings, supply lines, shutoff valves, and the drain pan for leaks
• Temperature setting - We set the temperature to about 120 degrees for safety and efficiency
• Written record - You receive a record of the service for your files and your insurer

How Often Should a Water Heater Be Maintained?

We recommend maintenance once a year for tank and tankless water heaters. Homes with very hard water, large households, or older heaters may benefit from more frequent flushing. Tankless units need an annual descaling flush to remove scale from the heat exchanger. Learn more about tankless water heaters.

The Anode Rod: Your Tank's Protection

Inside every tank water heater is an anode rod, a metal rod that corrodes so your steel tank does not. Once the rod is used up, the tank itself starts to rust. Replacing a worn anode rod before that happens can add years to the life of your heater.

Signs Your Water Heater Needs Service

• Popping, rumbling, or crackling noises
• Hot water that runs out faster than it used to
• Rusty, cloudy, or smelly hot water
• Water in the drain pan or around the base
• A pilot light that goes out or a yellow burner flame

If you notice these signs, you may need water heater repair rather than routine maintenance. If your heater is more than 10 years old, ask about water heater replacement.

Water Heater Maintenance Cost in Houston

Water heater maintenance at Nick's Plumbing typically costs $200-$1,000. A standard tank flush and inspection is at the low end of that range, while tankless descaling, anode rod replacement, or repairs found during the inspection add to the cost. We confirm the price before any work begins.
