Clarksburg's homes are new by regional standards, so many water heaters here are original units now reaching the age where elements, igniters, valves and anodes start to wear. Most of those faults are repairable, while a leaking tank shell means replacement. Call the number on this page to be connected with a local plumber in Clarksburg.
Clarksburg is one of the youngest communities in Montgomery County: the median home was built around 2010, and roughly 84% of housing units went up between 2000 and 2019. That means a large share of heaters are still the ones the builder installed, and many of them are now old enough for first-round failures. WSSC Water supplies most of the area and its report lists UV disinfection, residual chlorine and an orthophosphate corrosion inhibitor. On the rural edges, the county's water and sewer categories assign some properties to individual wells and onsite systems, so check yours if you are outside the newer neighborhoods.
What to do now
- Stop any leak by closing the cold-water valve feeding the heater.
- Kill power at the breaker for an electric heater, or set the gas control to off.
- If there is a gas smell, leave the home first, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1, from outside.
- Find the manufacture date on the rating label; if it isn't printed plainly, it is usually coded into the serial number.
- If the house still has its original heater, look for leftover warranty paperwork from the builder or manufacturer.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Gas heater clicks but won't light | Igniter or flame sensor failure |
| Power-vent unit shuts down | Blower motor or pressure switch fault |
| Electric heater, no hot water | Element or thermostat failure, tripped reset |
| Relief valve drips after heating | Thermal expansion, high pressure, worn valve |
| Hot water smells of sulfur | Anode rod reaction |
| Puddle under the tank | Drain valve, fitting or tank failure |
What affects cost
Newer heaters often use electronic ignition, power venting or sealed combustion, and those parts cost more than an old-style thermocouple. A first-time flush on a tank that has never been drained can take longer if the drain valve is stiff. Heaters in finished basements or tight closets take more time to work around. Original heaters in the newest homes may still carry part of a manufacturer warranty, which can cover the part even when labor is billed. If replacement is the answer for a gas unit, Montgomery County requires a plumber or gasfitter registered with WSSC Water and a WSSC permit for that work.
