Tank Water Heater Flushing in Londonderry
Hard water leaves calcium and magnesium sediment at the bottom of the tank. This layer insulates the water from the burner or lower element, wasting energy and causing popping sounds. We connect a hose to the drain valve and flush the tank until the water runs clean. For heavy buildup, we may stir and flush in several cycles. A clean tank heats faster and runs quieter.

Water Heater Leak Detection and Prevention in Londonderry, NH
Leaks are a common issue that can lead to significant water damage if not caught early. Our maintenance service includes a thorough inspection of all water heater connections, pipes, and the tank itself for any signs of leaks or corrosion. We examine the drain pan and surrounding area for moisture. Early detection and repair of small leaks can prevent larger, more damaging problems, protecting your home's floors and interior from water damage.
Electric Water Heater Element Service in Londonderry, NH
Electric water heaters use upper and lower heating elements controlled by thermostats. Sediment can coat the lower element and cause it to fail. We test both elements and thermostats with the power off and replace parts as necessary. A failed element is often the reason for lukewarm water or running out of hot water quickly. Proper testing avoids replacing parts that are still good.
Annual Maintenance Plans for Londonderry, NH Homes
To make water heater maintenance simple and worry-free, FVR Plumbing offers annual maintenance plans for homes in Londonderry, NH. These plans give your water heater regular, scheduled attention, so you never forget crucial service. Members often receive priority scheduling and discounts on repairs, providing peace of mind and long-term savings on your hot water system.
Gas Water Heater Burner and Venting Check in Londonderry
Gas water heaters need a clean burner and a proper vent to run safely and efficiently. We inspect the burner flame, clean the combustion chamber and check the thermocouple or flame sensor. The vent is checked for proper draft and secure connections. Blocked or loose vents can let carbon monoxide into your home. We also check the gas line and shutoff valve for any leaks.
Tankless Water Heater Descaling in Londonderry
Tankless units are particularly sensitive to hard water scale, which clogs the heat exchanger and triggers error codes. We isolate the unit with its service valves and circulate a descaling solution with a pump for the recommended time. We also clean the inlet water filter and check the unit's error history. Most manufacturers recommend descaling at least once a year in hard water areas. Regular service keeps flow rates and temperatures consistent.
Preventative Maintenance for All Brands in Londonderry
Our team is experienced in maintaining all major water heater brands, including Rheem, AO Smith, Bradford White, Noritz, Rinnai, and more. Regardless of your unit's manufacturer, we have the tools and knowledge to perform the necessary checks and adjustments. We follow manufacturer guidelines so your warranty stays valid and your model gets the exact care it needs to run efficiently and reliably in your Londonderry home.

Maintenance Cost Versus Replacement in Londonderry, NH
A water heater tune-up costs a fraction of a new unit, which can run well over a thousand dollars installed. Regular flushing and anode replacement can help a tank reach the high end of its rated lifespan. Tankless units in particular can last many years with proper descaling. If your heater is near the end of its life or leaking from the tank, we will tell you honestly. We help you weigh repair against replacement with real numbers.

Regular water heater maintenance is crucial for homes in Londonderry, NH, because minerals in the water settle as sediment and cut efficiency over time. Water in much of New Hampshire is soft and often slightly acidic, which can slowly corrode copper pipe and cause pinhole leaks.
