Water Heater Maintenance

Annual maintenance extends your water heater's life, maintains efficiency, and catches problems before they become emergencies — for both tank and tankless units.

About This Service

Water Heater Maintenance

Water heaters are often the most neglected appliance in a home — set and forgotten until they fail. But like any mechanical system, they benefit from regular maintenance that prevents the gradual buildup of sediment, mineral scale, and corrosion that shortens their service life.

For tank water heaters, annual maintenance includes a tank flush to remove sediment buildup, inspection of the anode rod (which sacrificially protects the tank from corrosion), testing the temperature-pressure relief valve, and verifying correct temperature settings. These steps alone can extend a tank's life by several years.

For tankless water heaters, annual descaling is the most critical maintenance task. Mineral deposits (primarily calcium) build up inside the heat exchanger over time, reducing flow rate and heat transfer efficiency — and eventually causing failure. Descaling flushes this buildup out before it can cause damage.

Is This Right for You?

Signs You May Need Water Heater Maintenance

Common indicators our Hudson Valley customers recognize before they call us.

Your Water Heater Has Never Been Serviced

Most water heaters are installed and forgotten until they fail. If yours has never been flushed or inspected, you're likely already past the point where sediment and anode depletion are reducing its life.

Your Water Heater Is 5+ Years Old

Annual service should begin in the first year and continue throughout the unit's life. By year 5 without maintenance, sediment buildup in a tank unit is typically significant.

You Have Hard Water

Hudson Valley water tends toward the harder side of the spectrum. Hard water accelerates both sediment buildup in tanks and scale buildup in tankless heat exchangers — making annual maintenance even more important.

Your Hot Water Doesn't Last as Long as It Used To

Reduced hot water capacity is often caused by sediment taking up volume at the bottom of the tank. A flush typically restores some lost capacity if the tank is otherwise sound.

You Hear Popping or Rumbling Sounds

Sediment-related noise during heating cycles is your tank's way of telling you it needs a flush. The longer you wait, the more stress is placed on the tank lining.

Your Tankless Unit Has Lower Flow Than It Used To

Reduced hot water flow rate from a tankless unit is almost always scale buildup in the heat exchanger. Annual descaling restores full flow and efficiency before permanent damage occurs.

How It Works

Our Water Heater Maintenance Process

A straightforward process from start to finish — no surprises, no hidden fees.

1

Inspection

We inspect all visible components — connections, valves, venting, and the unit itself — for signs of leaks, corrosion, or wear.

2

Tank Flush or Descale

Tank units are flushed to remove sediment. Tankless units undergo a full descaling flush to clear mineral buildup from the heat exchanger.

3

Component Check

Anode rod inspection and replacement if depleted. T&P valve test. Thermostat verification. Gas supply check for gas units.

4

Report & Recommendations

We report our findings and advise on any upcoming concerns — so you can plan proactively instead of reacting to a failure.

What's Included

Our Water Heater Maintenance Services

Everything covered under our water heater maintenance offering for Hudson Valley homeowners.

Tank Sediment Flush

Annual flushing removes mineral sediment that accumulates at the bottom of tank water heaters, reducing efficiency and accelerating tank corrosion.

Anode Rod Inspection & Replacement

The anode rod is the main protection against tank corrosion. We inspect it annually and replace it before it's fully depleted — extending tank life significantly.

T&P Valve Testing

The temperature-pressure relief valve is a critical safety device. We test it annually to confirm it operates correctly and won't fail under pressure.

Tankless Descaling Service

Circulate descaling solution through your tankless unit to dissolve calcium and mineral buildup in the heat exchanger — restoring efficiency and extending life.

Gas Connection & Venting Check

Verify gas connections for leaks and confirm venting is clear and properly connected — critical safety checks for all gas water heaters.

Temperature & Efficiency Verification

Confirm your unit is delivering water at the correct temperature and operating efficiently — we flag issues before they become service calls.

FAQ

Water Heater Maintenance — Common Questions

Answers to the questions we hear most from Hudson Valley homeowners.

How often should a water heater be serviced?
Annual maintenance is recommended for all water heater types. In areas with particularly hard water, tankless units benefit from descaling every 6–12 months depending on water hardness. Annual maintenance is the most cost-effective way to extend your unit's life.
What is the anode rod and why does it matter?
The anode rod is a sacrificial metal rod (usually magnesium or aluminum) inside your tank that corrodes preferentially, protecting the steel tank walls from rust. Once depleted, the tank itself begins to corrode rapidly. Replacing the anode rod before it's fully consumed is one of the most impactful maintenance actions for extending tank life.
Can I flush my own water heater?
A basic tank flush (connecting a hose and draining the tank) is a DIY-possible task, but many homeowners skip it because of the effort involved. For tankless descaling, the process requires a submersible pump and descaling solution — it's more involved. We recommend having a professional handle the annual service to ensure all components are inspected at the same time.
