A tank water heater needs a yearly flush to clear sediment and an anode rod check every few years. The anode rod is the metal rod inside the tank that corrodes so the tank does not. A tankless unit needs a yearly descale. Hard well water may call for more frequent care.

Signs you need water heater maintenance

Maintenance is easiest before there is a problem. These signs mean your water heater is due for care now.

  • Years of sediment may be sitting on the bottom, wasting fuel and stressing the tank.
  • Sediment is trapping water under it. A flush can help if caught early.
  • Often a reaction between the anode rod and certain well water. A different anode can fix it.
  • Anodes wear out. Once gone, the tank itself starts to corrode.
  • Scale inside the heat exchanger restricts flow and heat transfer.
  • Hard or iron-rich water speeds sediment and scale build-up.

How water heater maintenance works with us

  1. Inspect the unit

    We check the tank or tankless unit, relief valve, venting and connections for leaks, rust or wear.
  2. Flush or descale

    Tanks are drained and flushed to clear sediment. Tankless units get a cleaning solution pumped through them.
  3. Check the anode rod

    On tanks, we pull and inspect the anode rod and tell you if it needs replacing.
  4. Test and report

    We refill, restart and test the unit, then tell you what we found and what to watch for.

What affects the price

Maintenance costs much less than a repair or early replacement, and it is the cheapest way to get more years from a water heater. Price depends on the type of unit and what the inspection finds. Ask us about your unit when you call.

Local water and the seasons

Many homes in the River Valley and along the shoreline draw water from private wells. Well water often carries more minerals and iron than town water, so sediment builds faster in tanks and scale forms faster in tankless units. Homes on wells benefit most from regular flushing and descaling.

Fall is a good time for maintenance. Winter puts the heaviest load on a water heater, and a clean tank or descaled tankless unit heats more efficiently when incoming water is coldest. For seasonal cottages near the beaches, a fall visit can include draining the heater before the house is closed for winter.

Common Questions

How often should a water heater be flushed?

Most manufacturers recommend flushing a tank water heater once a year. Homes on hard or iron-rich well water may benefit from flushing more often. Flushing removes sediment that wastes fuel, causes rumbling noises and can shorten tank life. A tank that has gone many years without flushing should be inspected first.

What does an anode rod do?

An anode rod is a metal rod inside a tank water heater. It corrodes on purpose so the steel tank does not. Once the rod is used up, the tank starts to rust from the inside. Checking it every few years and replacing it when worn can add years to a tank's life.

Frequently Asked Questions

Many homeowners can, but take care. The water is hot, old drain valves can break or leak, and a gas unit must be set correctly before draining. If your tank has never been flushed in many years, have it inspected first, since stirring up heavy sediment can cause a leak.

This usually comes from bacteria in the water reacting with the anode rod, and it is more common with well water. Swapping the anode for a different type, such as aluminum zinc or a powered anode, often fixes it. We can check the rod and recommend a fix during a maintenance visit.

Most manufacturers call for descaling once a year. Homes on hard well water may need it every six months. Signs that a descale is overdue include lower water temperature, reduced flow and error codes. Service valves on the unit make descaling faster and easier.

Yes. Sediment and scale are two of the main reasons water heaters fail early. A yearly flush keeps the tank bottom clear, a healthy anode rod protects the tank from rust, and descaling protects a tankless heat exchanger. Regular care also helps the unit use less fuel.

If the house will be unheated over winter, yes. Water left in a tank or tankless unit can freeze and crack it. Draining the heater and the supply lines before closing the house protects them. Turn off the fuel or power first, and refill the tank before turning it back on.
