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 Quantico
The Town of Quantico is tiny, with about 50 owner homes and a median build year of 1950. Most of the housing in ZIP 22134 is on Marine Corps Base Quantico, where Liberty Military Housing manages the family quarters. If you live in the Town, your water heater is likely in an older home, and the plumbing behind it reflects that age. The base is federal property, so Prince William County does not serve it. If you are on base, your repair goes through Liberty, not us. This page is for the Town, where we handle the work directly.
The Town runs its own small water system and buys treated surface water from the base’s Mainside system. The EPA lists this system at 175 service connections. Because the water is treated surface water, sediment can build up in a tank over time, especially in older units. A flush is a simple way to clear that out, and it’s part of the maintenance we recommend. If your heater is older and you’re hearing rumbling or seeing brown water, a descale or flush is a good first step before you consider a full replacement.
Since the Town handles its own zoning but relies on Prince William County for building permits, the paperwork for your new heater goes to the county’s Building Development Division. If a tank fails, the state rule lets us begin the swap right away, as long as the permit request hits the county desk by the end of the next business day. Our quote covers this administrative step, so you don’t need to file anything yourself. For a flush, no permit is needed, but we can advise you on the next step if the tank is near the end of its life.
The weather here can be extreme. The Quantico weather station records show heat indices up to 118 degrees in July 2011, and wind chills down to -5 degrees near the Potomac in December 2022. Cold snaps can stress a water heater, especially if it’s in an unheated space. If you’ve had a freeze or a storm, check your heater for leaks or unusual sounds. The town is also near the tidal Potomac, so if you’ve seen water on the ground after a storm, make sure your heater is dry before you turn it back on. If any part of a gas heater has been under water, don’t relight it. Call us to inspect it first.
When it’s due
Sediment from the base’s surface water settles in the tank over years. Rumbling means the burner is fighting through it. Brown water means the sediment is stirring up. A flush clears it, but if the tank is over ten years old, it may be time to replace 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.
Prince William County’s Building Development Division issues the permit, even though the Town handles zoning. Our installed prices include the permit and inspection, so you don’t have to file it yourself. For a burst tank, the work can start first, but the permit must reach the county by the next working day.
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 had a really pleasant personal experience with Swiftpro when my water heater went out. The pricing was very reasonable compared to the many other HVAC companies I sought quotes from. I highly recommend them
