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 Broad Run
A flush page usually starts with the water company’s hardness figure. Across most of Broad Run there’s no water company to quote. Fauquier County plans public water only for its service districts, which leave Broad Run out, and on the Prince William side the County’s own map puts no Broad Run house near a Prince William Water main. What the county does have is Virginia Cooperative Extension’s well clinics: from 2012 to 2017 it tested 97 Fauquier samples from wells 50 to 705 feet deep, nearly all of them drilled.
The figure that matters most for a water heater is pH. Close to half the samples, 46 percent, came in below 6.5, and Extension’s report says water that acidic can pull metal out of copper pipe and brass fittings. Inside a tank, the anode rod takes that wear so the steel doesn’t, and on corrosive water it gets used up sooner. So on a Broad Run well, the anode check that comes with the flush is worth as much as the draining.
The other thing well water brings is grit. The geologic map puts phyllite and metasiltstone under the hamlet, and a drilled well draws through rock, so fine particles ride along. A sediment filter was the most common treatment Extension found on Fauquier wells, with manganese and iron on its list of frequent problems. Whatever gets past a filter, or comes up in a house without one, settles where the tank’s water sits still and heats.
A few homes at the ZIP’s southern edge near Lee Highway sit inside FCWSA’s New Baltimore service district. If your bill comes from FCWSA, your water is public and the Authority flushes its mains on a posted schedule; the rest of New Baltimore’s 2026 rounds fall in early November and the week before Christmas. Book the tank flush after one of those, so the heater fills with water that’s already cleared.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
ZIP 20137 as a whole: every Broad Run address. About one home in six of them is on the Prince William County side.
When it’s due
On a well, a sulfur smell from the hot tap alone usually comes from a reaction at the anode rod, not from the well. A flush clears the tank, and if the smell comes back, a different kind of anode often settles it. Smell on both taps is a question for a well contractor.
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.
A softener, an acid neutralizer and a sediment filter each change what reaches the tank, and softened water wears an anode faster. Ask whether the tech looks at the equipment by the pressure tank before deciding how often you need a flush.
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.

I am very happy with the service I received in installing my water heater. Tyson and the crew were very kind and cleaned everything up before they left. I would really recommend this company.

Questions
Once a year is a sound default, since there’s no published hardness number for a private well. Sooner if a sediment filter cartridge browns quickly, if the tank starts popping, or if your well has had a pump or a tank replaced, which stirs up grit for a while afterward.
No, those are a well contractor’s. The flush and the plumbing check cover the water heater and the house’s own lines, and we’ll tell you what we notice on the way, like a pressure gauge that swings wide or a filter housing that weeps.
$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.
