Water Heater Expansion Tank Service in Derry, NH
Many modern plumbing systems include an expansion tank connected to the water heater. This tank takes up excess pressure created during the heating cycle, protecting your hot water tank and other plumbing fixtures. Our maintenance includes checking the expansion tank's air pressure and overall condition. Proper expansion tank function is key to preventing premature wear on your hot water tank and protecting system integrity.

Gas Burner and Venting Tune-Up in Derry, NH
On gas tanks we clean the burner, inspect the thermocouple or flame sensor and look for soot, rust flakes or scorching around the combustion chamber. We check the draft hood and vent connector for proper slope and secure joints. Dust and lint from garages can block the flame arrestor screen on newer FVIR models, which causes the pilot to drop out. A clean burner gives a stable blue flame and lower gas bills.
Emergency Hot Water Tank Inspections in Derry
If you notice sudden changes in your hot water tank's performance, like strange noises, discolored water or a sudden drop in hot water supply, FVR Plumbing offers emergency inspections in Derry. While not a full maintenance, we can promptly diagnose the issue and advise on immediate steps. That usually includes a focused maintenance procedure to restore function and prevent further damage.
Anode Rod Inspection and Replacement in Derry, NH
The anode rod, often called the sacrificial rod, is essential for preventing corrosion inside your hot water tank. Water chemistry varies from one neighborhood to the next, and it affects the rod's lifespan. Our technicians inspect the anode rod for wear and recommend replacement if it's significantly corroded, typically every 3 to 5 years. Replacing a worn anode rod is a cost-effective way to protect your tank from rust and leaks, sparing you a full tank replacement.
Sediment Flushing & Cleaning in Derry, NH
Over time, minerals and sediment settle at the bottom of hot water tanks, reducing efficiency and potentially leading to premature failure. Our maintenance includes a thorough flushing of the tank to remove these deposits. This process helps your tank heat water more evenly and quietly, a vital step for any hot water tank in Derry, NH, where mineral content in the water is a frequent concern.
Anode Rod Inspection & Replacement in Derry, NH
The anode rod is your hot water tank's sacrificial defense against corrosion. Testing well water around Derry is the right first step before choosing a treatment system or filter. During our maintenance, we pull and inspect the anode rod. If it's badly depleted, we recommend and perform a replacement to extend the life of your tank in Derry, NH, preventing rust from eating away at the tank lining.
Commercial Hot Water Tank Maintenance in Derry, NH
Businesses in Derry, NH rely heavily on consistent hot water for their operations. Our commercial hot water tank maintenance services are tailored to the higher demands of commercial units. We provide thorough inspections, flushing and component checks so your business avoids costly downtime from hot water system failures. Keeping your commercial hot water tank in peak condition is vital for customer satisfaction and smooth operations.

Maintenance Versus Replacement Costs in Derry, NH
A yearly flush costs a small fraction of a new tank, and a new installed tank often runs $1,400 to $3,000 or more. We give you an honest read on whether maintenance is still worth it. If a tank is past 10 to 12 years old, shows rust at the base or leaks from the seams, we will tell you replacement is the smarter spend. When the tank still has life, maintenance keeps it running efficiently for years.

In mineral-heavy water a magnesium rod may last three to five years. We measure it at every visit so you replace it before the tank lining begins to rust.
Our technicians are trained to service all major hot water tank brands, including Rheem, AO Smith, Bradford White, State, Kenmore and more. We have the experience to handle various models, whether gas or electric.
Many manufacturers, including Rheem, A.O. Smith and Bradford White, expect regular maintenance and can deny claims for sediment damage. Keeping service records safeguards your warranty.
Neglecting maintenance can lead to inefficient operation, higher energy bills, premature tank failure from corrosion or sediment buildup, and potential safety hazards from a malfunctioning pressure relief valve. Regular service heads off these costly and dangerous issues.
That sound is water trapped under a layer of sediment boiling as the burner fires. A flush often quiets it, though very old hardened scale may not come out completely.
Regular, professional maintenance can often be a condition for keeping your manufacturer's warranty valid. Check your warranty documentation, but in most cases, proof of annual service can help keep your warranty intact.
