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 Waterford
Waterford homes rely on private wells for drinking water. The county’s water feasibility study notes that treating the groundwater for iron and manganese is likely needed. These minerals are common in western Loudoun groundwater. They do not vanish in the pipe. They settle in the bottom of your water heater tank. Over years, that sediment builds up, coats the heating element, and reduces the tank’s efficiency. A flush clears that layer out. You can see what drained out and decide if the tank is still sound.
Most owner homes in ZIP 20197 heat with propane, and none use natural gas. That setup means your water heater is likely a propane tank. The median owner home was built in 1996, so a tank that came with the house is now about thirty years old. Many are on their second or third unit. Since 98 percent of housing is detached, you likely have a standard tank in a basement, garage, or utility room. A flush is the easiest way to check the condition of a tank that has been running for decades without a service visit.
The village sits in the Catoctin Valley. Some parcels lie within the 100-year floodplain. If your water heater is in a basement near the creek, check its elevation relative to past flood levels. In 2020, South Fork Catoctin Creek rose to 11.11 feet, and water came up to a building on Main Street. A heater that sat in floodwater gets checked before it runs again. Sediment from floodwater can clog the drain valve or corrode the interior faster than normal well water would.
Loudoun County requires a permit to swap a gas or propane water heater. Since October 2025, a replacement that keeps the same BTUs in the same spot needs no plans. If your tank bursts, Virginia law allows the replacement to start first, as long as the permit application reaches the county by the end of the next working day. The permit and inspection are already included in our installed price. A flush helps you decide if the tank is worth keeping or if it is time to move to the next unit.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
ZIP 20197 as a whole: every Waterford address, the village included. The Census place for the village alone has too few homes for steady figures.
When it’s due
Waterford well water can run high in iron and manganese. Over time, these minerals can coat the heating elements and tank interior, causing rust-colored water or reduced hot water output. A flush removes the sediment, and a replacement may be needed if the tank is corroded.
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.
Yes. High iron and manganese levels can affect tank longevity. A good technician will ask about your well water quality and recommend a flush frequency or specific tank type if needed. This ensures the unit lasts longer and performs well with your specific water source.
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.

SwiftPro delivered and installed a 75 gallon AO Smith water heater. Zabi was very professional in his communication, plumbing, testing, and cleanup. Good crew to move new heater to basement utility room and take out the old heater.

Questions
Yes, but consider your usage. Propane heats water faster and is common in Waterford. Electric is simpler but may require larger tanks or higher capacity if you use a lot of hot water. We can help you compare options based on your home’s needs.
No. The permit and inspection are included in the installed price. The price book covers the labor, parts, and county requirements, so you get a clear number upfront.
