Why Preventive Maintenance Matters

Preventive maintenance is the key to maximizing your water heater’s lifespan and efficiency. Regular care can:

Reduce the risk of leaks, corrosion, and tank failure
Improve energy efficiency and lower utility bills
Ensure a consistent supply of hot water
Prevent costly emergency repairs or replacements
Protect your home from water damage and mold

Ignoring your water heater until something goes wrong is a recipe for disaster. By investing a little time and effort now, you can save money and avoid headaches in the future.

Understanding Your Water Heater: Types and Common Issues

There are two main types of residential water heaters: tank-style (either gas or electric) and tankless (on-demand). Each has unique maintenance needs and potential problems.

Tank-Style Water Heaters

These are the most common and store hot water in an insulated tank. Common issues include:

Sediment buildup
Rust and corrosion
Leaks from valves or fittings
Faulty heating elements or thermostats (electric models)
Pilot light or burner problems (gas models)

Tankless Water Heaters

These units heat water as it flows through the system, offering energy savings and endless hot water. Common issues include:

Mineral scaling on the heat exchanger
Clogged inlet screens or filters
Ignition or burner problems (gas models)
Sensor or electronic failures

No matter your type, regular maintenance is essential. If you’re unsure about your water heater model, contact an expert at Repairmen.com or call 833-864-6908.

Essential Steps to Prevent Water Heater Problems

1. Flush the Tank Annually

Sediment from hard water accumulates at the bottom of tank-style water heaters, causing popping noises, reduced efficiency, and even tank failure. Flushing the tank removes this sediment.

How to Flush Your Water Heater:

Turn off the power (electric) or set the gas control to “pilot” (gas).
Shut off the cold water supply.
Attach a garden hose to the drain valve and run it to a drain or outside.
Open a hot water tap in your home.
Open the drain valve and let the tank empty.
Briefly turn on the cold water to stir up and flush out remaining sediment.
Close the drain valve, remove the hose, and refill the tank.
Restore power or gas and check for leaks.

If you’re not comfortable flushing your tank, schedule a professional flush or call 833-864-6908.

2. Inspect and Replace the Anode Rod

The anode rod is a sacrificial metal rod inside the tank that attracts corrosive minerals, protecting the tank from rust. Over time, it gets used up and must be replaced.

How to Check the Anode Rod:

Turn off power/gas and water supply.
Drain a few gallons from the tank.
Unscrew the anode rod from the top of the tank.
Replace if it’s less than ½ inch thick or coated in calcium.

Check the anode rod every 2–3 years. If you need help, book an inspection with Repairmen.com or call 833-864-6908.

3. Test the Temperature and Pressure Relief (T&P) Valve

The T&P valve is a safety device that prevents excess pressure or temperature from causing the tank to explode.

How to Test:

Place a bucket under the discharge pipe.
Lift the valve’s lever briefly—hot water should flow out.
If it doesn’t, or if the valve leaks afterward, replace it.

A faulty T&P valve is a serious hazard. Get a free safety check or call 833-864-6908 if you’re unsure.

4. Set the Thermostat to the Right Temperature

Setting your water heater thermostat to 120°F is ideal for safety and efficiency. Higher temperatures increase the risk of scalding and accelerate sediment buildup.

Check and adjust the thermostat annually.
For gas models, follow the manufacturer’s instructions.

If your water is too hot or too cold, request a thermostat inspection or call 833-864-6908.

5. Inspect for Leaks, Rust, and Corrosion

Regularly check around your water heater for:

Puddles or dampness
Rust on the tank or fittings
White, chalky deposits (signs of hard water)

Early detection can prevent major water damage. If you spot any of these signs, get a free leak inspection or call 833-864-6908.

6. Insulate the Tank and Pipes

Insulating your water heater and hot water pipes reduces heat loss, saves energy, and prevents pipes from freezing in cold climates.

Use a water heater blanket (for older tanks, not newer energy-efficient models).
Insulate exposed hot water pipes with foam sleeves.

7. Schedule Regular Professional Maintenance

An annual professional inspection and tune-up can catch problems early, extend your heater’s life, and keep your warranty valid.

Professionals can flush the tank, check the anode rod, test valves, inspect gas/electric connections, and more.
They can also recommend upgrades or replacements if your unit is aging or inefficient.

Preventive Tips for Tankless Water Heaters

Descale the heat exchanger annually (more often in hard water areas).
Clean the inlet filter every 6–12 months.
Check for error codes and address them promptly.
Inspect venting and gas connections for leaks or blockages.

Signs That Your Water Heater Needs Immediate Attention

Even with proper maintenance, problems can arise. Watch for these warning signs:

No hot water or inconsistent temperature
Strange noises (popping, rumbling, hissing)
Water leaks or pooling
Rusty or discolored water
Foul-smelling water
Low water pressure
Pilot light or burner issues (gas models)
Frequent circuit breaker trips (electric models)
Visible rust or corrosion

FAQs: Preventing Water Heater Problems

How often should I flush my water heater?
Once a year is recommended, or every six months in hard water areas.

How do I know if my anode rod needs replacing?
Check every 2–3 years. Replace if it’s less than ½ inch thick or heavily corroded.

Is it safe to do water heater maintenance myself?
Basic tasks like flushing and checking for leaks are safe for most homeowners. For electrical, gas, or major repairs, call a professional.

How long does a water heater last?
Most last 8–12 years with proper care. Tankless models can last up to 20 years.
