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.
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.

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.
Our Water Heater Maintenance Process
A straightforward process from start to finish — no surprises, no hidden fees.
Inspection
We inspect all visible components — connections, valves, venting, and the unit itself — for signs of leaks, corrosion, or wear.
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.
Component Check
Anode rod inspection and replacement if depleted. T&P valve test. Thermostat verification. Gas supply check for gas units.
Report & Recommendations
We report our findings and advise on any upcoming concerns — so you can plan proactively instead of reacting to a failure.
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.
