Gas tanks in old basements, electric tanks in new condos, and the City’s case for going electric.
In the 1950s and 60s houses of West Falls Church, Lake Barcroft and the older City streets, you’ll most often find a gas tank down in the basement beside the furnace. Replacing it means a permit whichever side of the City line you’re on, and the City casts the widest net: any work on a natural gas appliance, even pulling one out, takes a gas permit. Floodwater does reach houses on a Falls Church address. On July 7, 2020, the National Weather Service logged flash flooding in the 6600 block of Barrett Road, and the water got into homes. A gas tank that sat in it shouldn’t be relit until someone has looked it over.
The City also makes its own case for electric. Its Electric Water Heaters page walks through electric tanks, tankless units and heat pump water heaters, and spells out what the switch takes: most electric models need a dedicated 240-volt circuit, a heat pump model needs at least 1,000 cubic feet of air around it and a spot that stays between 40 and 90 degrees, and new wiring means an electrical permit. A roomy basement can work; a small closet usually can’t.
Hard water wears the tank down too. Most of Falls Church typically gets Washington Aqueduct water through Fairfax Water, and the Aqueduct’s two plants tested from 5.6 to 10.9 grains per gallon across 2025, hardest in December. Those minerals settle as grit under the burner year after year, and draining them is the point of a yearly flush.
Nearly half the homes in the City, and over six in ten in Bailey’s Crossroads, are in buildings of ten units or more. Heaters there tend to be electric tanks squeezed into closets, and the pan under one is all that stands between a slow leak and the neighbor’s ceiling.

- In older houses the gas water heater often shares a chimney with the furnace, and a new high-efficiency furnace can leave it alone on a flue that’s too big.

What a new water heater costs in Falls Church.
Installed, from our water heater estimator, which is the price book. Everything is in the number: the permit and the inspection, the expansion tank, the drain pan, hauling the old one away, and the labor.

- Power vent tank, installed$5,957 to $7,494

How the house vents picks the row; where you land inside it is the tank size and the warranty. A hybrid heat pump water heater is quoted at the visit, never from a page.
Keeping the one you have? A yearly water heater flush slows the sediment down: $99 right now, normally $199. A tankless descale is $300, regularly $350. Or get the flush every year with Comfort+ membership, $199 a year, along with a dryer vent cleaning, a sewer camera inspection and heating and cooling maintenance visits.
What a failing water heater in Falls Church usually does.
Soot at the burner in a finished basement
When a basement gets finished around a gas water heater and furnace, the small room they end up in may not let in enough air to burn cleanly. Soot around the burner, or a flame that lifts and flickers, is the sign. That’s a safety call, not a part.
The pilot won’t stay lit
On a gas tank that’s usually the thermocouple or the gas valve, both repairs. A burner that lights but smells of exhaust is different: shut it off and call.
Water on the floor around it
A drip from a valve can be fixed. Water from the tank itself can’t; once the lining goes, the only fix is a new heater, and sooner beats later.
After a storm in Falls Church, check the water heater.
A water heater usually sits on the lowest floor of the house, so it’s one of the first things standing water reaches. Three checks, then call us.
Water reached the burner or the gas controls
Leave it off and don’t relight it. The warning label on a gas water heater says not to use it if any part has been under water, and to have a service technician replace the gas control.
An electric tank sat in water
Shut its breaker off at the panel, but only from somewhere dry. The elements and the thermostats get checked before it heats again.
Water around it after the rain stopped
Mop it up and look again in an hour. Water that comes back with no rain is the tank or a valve, not the storm.
Call us after a storm and we’ll check it: the gas control or the elements, the burner, the venting and the drain pan. If it has to be replaced, you get the price in writing before anything comes out.
Who signs off on a new water heater in Falls Church.
City of Falls Church
The City of Falls Church wants a gas permit for any work on a natural gas appliance, taking one out included, so a gas water heater swap is permit work even like for like. Rewiring for an electric one takes an electrical permit. Source.
Inside the City the statewide rule holds: an emergency equipment replacement can start first, as long as the permit application reaches the building official by the end of the next working day. Source.
Fairfax Water has run the City’s water system since January 3, 2014, and its rules hold inside the City: a minimum of 20 psi at the main in the street, no promise of an even pressure, and a pressure reducing valve that is the customer’s to buy, install and keep up. Source.
Fairfax County
Fairfax County requires a permit to replace any gas appliance, even like for like: a gas water heater, furnace or boiler. Replacing a fuel-burning appliance also needs a chimney vent certification. Source.
How to pick the best water heater installer in Falls Church.
Questions worth asking anybody who quotes you, us included.
Will they look at the room before quoting a heat pump water heater?
By the City’s own guidance, a heat pump model needs at least 1,000 cubic feet of air and a room that stays between 40 and 90 degrees. A quote that never asks about the room is a guess.
Is the permit in the price?
A gas water heater always needs a permit, an electric one often does, and skipping it tends to surface when the house sells. Ask whether the quote includes it and the inspection.
Is there an expansion tank in the quote?
Most houses here have a check valve or a pressure reducer on the incoming line, so the heated water has nowhere to go. An expansion tank gives it somewhere, and leaving it out is how quotes come in low.
Will they tell you when a repair will do?
A thermocouple, an element or a valve is a repair, not a new heater. A good plumber says so, and saves the replacement talk for a leaking tank.

Water heater questions from Falls Church.
Does the City of Falls Church want a permit for a new water heater?
If it burns gas, yes: the City wants a gas permit for any work on a natural gas appliance, removal included, and its page names gas work and wiring changes as the triggers. Across the line, Fairfax County wants its own permit and a chimney vent certification. Our installed prices carry the permit on either side.
Can I switch from a gas water heater to an electric one in Falls Church?
Usually, if the electrical panel has room for a dedicated 240-volt circuit. The City suggests having a licensed electrician check your capacity first, the gas line gets safely capped, and new wiring takes an electrical permit. A standard electric tank is the simple version; a heat pump model needs the room described above.
Why does my Falls Church water heater rumble?
Sediment. Falls Church water runs moderately hard to hard, and those minerals collect under the burner, where water boils up through them with every cycle. A flush clears some of it out, and it’s $99 right now with a whole-home plumbing check (normally $199). A tank that has rumbled for years is usually telling you to price the next one.
How much is a new water heater in Falls Church?
Installed, with the permit, the expansion tank, the pan and the haul-away: an electric tank $2,757 to $5,493, a gas or propane tank on the flue you have $3,379 to $5,485, a power vent tank $5,957 to $7,494, and a tankless unit $8,886 to $10,486. The estimator gives your exact number in about a minute.
