Gas Burner and Venting Tune-Up in Dover, 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 clog 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.

We understand the urgency of a broken hot water tank and strive to restore your comfort quickly and efficiently.
Electric Element and Thermostat Service in Dover
Electric tanks rely on upper and lower heating elements that get crusted with scale in hard water. We test each element with a meter, check the thermostats and look for scorched wires at the terminal block. If an element has failed we replace it with the matching wattage and voltage. Many families who think they need a new heater just need a lower element and a flush.
Gas and Electric Water Heater Checks in Dover, NH
Whether your home in Dover, NH uses a gas or electric hot water tank, our maintenance covers the specific needs of each. For gas units, we inspect burner assemblies, gas lines and vent systems for safety and efficiency. For electric units, we check heating elements, wiring and thermostats. Our detailed checks ensure all energy sources are operating correctly and safely.
Relief Valve and Expansion Tank Testing in Dover
The temperature and pressure relief valve is the part that keeps a tank from becoming dangerous. We lift the lever, confirm it opens and reseats and check the discharge line for proper material and termination. We also check your thermal expansion tank pressure with a gauge, since a waterlogged expansion tank lets pressure jump every heating cycle. High street pressure is not unusual in many service areas, so we test static pressure at a hose bib too.
Burner and Pilot Light Maintenance in Dover, NH
For gas hot water tanks, proper burner and pilot light operation is essential for efficient heating. Our service includes cleaning the burner assembly to remove dust and debris that can interfere with combustion. We also check and adjust the pilot light, ensuring it ignites reliably. This attention to detail prevents common issues like intermittent hot water or complete heating failure, which can be stressful for homeowners in Dover, NH.
Commercial and Rental Tank Maintenance in Dover
Property managers, restaurants and small offices often run several tanks that work much harder than a home unit. We set up scheduled maintenance for landlords and businesses, flushing each tank and logging the anode condition and valve test date. Records like these help with insurance and with planning replacements before a tank fails during business hours. We service 50 to 100 gallon commercial models as well as residential tanks in rental units.

Frequently Asked Questions About Hot Water Tank Maintenance in Dover
The cost for hot water tank maintenance in Dover, NH usually ranges from $100 to $250, depending on the tank type, age and specific services required like anode rod replacement. We provide a detailed quote before any work begins.
FVR Plumbing stands behind our work. While maintenance services generally don't have long-term warranties like new installations, we guarantee our workmanship for a specific period. Any parts replaced during maintenance will carry their manufacturer's warranty.
The anode rod, also known as a sacrificial rod, is a metal rod inside your hot water tank designed to corrode before the tank itself. It protects the tank lining from rust and corrosion, which matters most when water carries a lot of minerals, and it lengthens the lifespan of your unit.
Many homeowners can do a basic drain with a garden hose. The risk is a plastic drain valve that breaks or will not reseal, and DIY flushes seldom include an anode check or relief valve test.
Routine hot water tank maintenance, such as flushing and inspections, usually does not require a permit in Dover. However, if major components are replaced or the entire unit is swapped out, a plumbing permit may be necessary. Our team handles all necessary permit applications.
Most manufacturers and plumbing experts recommend yearly hot water tank maintenance. This is especially true where water is hard, since minerals speed up sediment buildup and anode rod depletion.
Most flushes and inspections take 45 minutes to 90 minutes. Heavily scaled tanks or anode replacements in tight closets can take a little longer.
Yes, softened water leaves far less scale in the tank. You will still want a annual check, since softened water can wear anode rods faster.
