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 Lovettsville
Within the town limits the water comes up from four Town wells, runs through sand filters that take out natural organic matter, iron and manganese, and gets chlorinated on its way to the mains. The Town’s report on 2025 lists every contaminant it detected that year, and hardness isn’t among them, so there’s no published number to time a flush by.
Without a number, the tank tells you. Water that spends time underground dissolves minerals from the rock, and heating drops them out as scale and grit across the tank bottom. Filters built for iron and manganese don’t take out the calcium and magnesium that make water hard. A hardness strip at the kitchen tap gives you your own figure. If the tank crackles as it heats, or white grit turns up in a faucet screen, it’s already overdue.
Propane heats about 44 percent of the town’s owner homes and electricity about 42, and the tank tends to match the heat. On propane, the burner sits right under the tank floor, so a crust there is what you hear, and we check the burner and flue while it drains. An electric tank’s lower element sits where the grit piles up. With the typical owner’s house built in 2007 and 232 of the town’s homes dating from the 2010s, plenty of first tanks are ten to twenty years old.
Past the town limits, homes in 20180 are generally on their own wells; Loudoun County says about a quarter of its residents, mostly in the west and north, depend on groundwater. Every private well draws its own water, so nobody can hand you a schedule for it: one tank may drain clear after a year while another runs sandy. We don’t work on wells or pumps. Our part starts at the water heater: we drain it, rinse until it runs clean, check the anode and test the relief valve.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
When it’s due
The Town filters hydrogen sulfide out of its well water, so a smell at the hot taps alone is usually being made inside the tank, at the anode rod. A flush with a change to a different anode material usually clears it up.
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.
Ask to see the first bucket. On Lovettsville well water, grit, flakes of white scale or dark specks tell you how fast your tank collects them, and that’s your schedule.
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.

Moises and Oscar responded quickly to our need for a new water heater. They came through with a quick and a professional install at a reasonable price. I trust Tyler, Moises, and the team at SwiftPro with my hvac and plumbing needs.

Questions
Nobody has published a figure. The Town’s 2025 report covers what it’s required to test, and hardness isn’t on its list. It is groundwater, which carries minerals, so plan on a yearly flush and let what drains out tell you if that’s often enough.
Yes. Unless the owner has added a softener, every mineral the well carries goes through the heat exchanger. Descaling a tankless runs $300, regularly $350, and it covers the inlet screen too, where well grit tends to stop first.
$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.
