What it costs
Same prices as our water heater flush page, anywhere in Northern Virginia, and you pay after the visit.
Tank water heater flush, with the plumbing check
$99, normally $199
Tankless descale, with the plumbing check
$300, regularly $350
Comfort+ membership, a water heater flush with a sewer camera inspection every year included
$199 a year
Both visits include a whole-home plumbing check: supply lines, shutoffs, a pressure reading, drains, toilets and traps.
One per household, owner-occupied homes, limited time. A leaking tank, or one that’s 15 years old, needs repair or replacement, not a flush.
More for the money: Comfort+ membership, $199 a year, includes the flush and its plumbing check every year, plus a sewer camera inspection, a dryer vent cleaning and heating and cooling maintenance visits.
What’s different in Orlean
There’s no public water in Orlean. Fauquier County runs public water only inside its designated service districts, and the Fauquier County Water and Sanitation Authority’s 2025 report lists sixteen systems with none of them here. Every house draws from its own well, and the rock mapped under the village is the Marshall Metagranite, a granite. Nobody publishes a hardness number for a private well, which makes the tank itself the evidence: whatever runs out of the drain valve shows what your well has been sending in.
Virginia Cooperative Extension ran well clinics in Fauquier from 2012 to 2017 and tested 97 samples, mostly from drilled wells 50 to 705 feet deep. Close to half were acidic, under pH 6.5. Acidic water is hard on metal, so on an Orlean flush the anode rod, the rod that corrodes so the tank doesn’t, is the part we’d pull and look at. And if the house treats that water with a calcite neutralizer, the neutralizer works by dissolving mineral into the water, which leaves it harder on its way to the heater. More mineral going in means more scale settling on the bottom of the tank.
Timing matters out here. At Warrenton 3 SE, the long-term station nearest the village, the median first fall freeze comes around November 1, and close to five nights a year drop to 10 degrees or colder. A flush drains through a hose, and a hose across a frozen lawn is asking for trouble. October, before the cold settles in, is the easy month for it.
Outages can send grit, too. When a storm knocks out the power, the well pump stops, and the first rush when it starts again can stir up sediment that ends up in the water heater. If the hot side runs cloudy or sandy after an outage while the cold side has cleared, the sediment is in the tank, and draining it is the fix. The well itself is a well contractor’s job.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Orlean’s own ZIP, 20128, is post office boxes only, so the Census Bureau maps no area for it. These are ZIP 20115 as a whole, the Marshall ZIP area Orlean sits in, Marshall included.
When it’s due
On well water, a sulfur smell from the hot taps only usually comes from the anode rod reacting with the water inside the tank. A flush helps for a while; a different anode usually settles it, and we price that before doing it.
That’s water boiling under a layer of sediment on the bottom of the tank. A flush clears it out.
Which is most houses. The drain valve at the bottom of the tank has usually never been opened.
Choosing who does it
Questions worth asking anybody you call, us included.
On a well with no water report, what drains out of the tank is the closest thing you have to one. Ask to see it: sand and grit, white flakes of scale and rust-colored water each point somewhere different.
The anode is the part that corrodes so the tank doesn’t, and the relief valve is the tank’s safety valve. A flush that skips both is just draining water.
A real descale isolates the heater at its service valves and pumps solution through the heat exchanger, then rinses it and cleans the inlet screen.

Had the water heater replaced and a quote for my HVAC. Both technicians were friendly and helpful. Prices were decent. Would use again.

Questions
Start with once a year. If the first flush runs heavy with scale or grit, keep it yearly; if it runs clean, the tank is in good shape. A tankless unit needs descaling on its maker’s schedule, which depends on hardness, so a hardness test of your well water tells you how often. A descale is $300 right now, regularly $350.
$99 right now for a tank, normally $199, with a whole-home plumbing check. A tankless descale is $300 right now, regularly $350. Comfort+ membership, $199 a year, includes the flush every year.
