What’s different in Calverton
Fauquier County’s comprehensive plan says everyone outside the Town of Warrenton relies on groundwater, and FCWSA runs none of its public systems in Calverton. So the water at every Calverton tap starts in a private well on the property. Wells and their pumps belong to a well contractor; we pick up once the supply pipe is inside the foundation wall.
Going out, the house ends at one of two tanks. The County’s 2017 sewer reaches Calverton only to fix properties with failing and failed drainfields, inside a boundary kept narrow on purpose. Inside it, a house drains to a STEP tank that pumps on to the County’s line; outside it, to its own septic system. We don’t pump or repair either tank, but a sewer camera inspection, $89 added to a visit, shows whether a backup is in the house’s pipe or past it.
The village plan puts an extensive floodplain through the middle of Calverton, and NOAA’s Storm Events records match it: Bastable Mill Road under water at Turkey Run in 2014 and near Brookfield Drive in 2018 and January 2024, and Bristersburg Road shut near Licking Run in August 2018. Ground that wet pushes water at basement walls and floor drains, and a sump pump that can’t keep up is a pump to replace; our sump pump replacement page has the one price.
Warrenton 3 SE, the NOAA station about six miles away, averages 98 nights a year at or below freezing and read 3 degrees on January 7, 2014. With frost depth at 24 inches in the County’s design criteria, a buried line is normally out of the frost’s reach; the pipe that freezes is the one above ground. An outside spigot that isn’t frostproof, a supply line along an outside wall or through a crawlspace, and the run to a detached garage or barn are where to look first.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Calverton’s own ZIP, 20138, is post office boxes only, so the Census Bureau maps no area for it. These are ZIP 20119 as a whole, the Catlett ZIP area that holds nearly nine in ten of the Calverton Census place’s homes.
What you’d notice
If the tubs and toilets slow after a heavy rain and come back after a few dry days, the trouble is likely past the house, in a drainfield that can’t soak water into ground that’s already full; that’s a septic company’s call. If they stay slow in dry weather too, the clog is more likely in the house line, and that’s ours to clear.
Galvanized steel supply pipe rusts from the inside, so the pressure falls slowly until a shower upstairs is a trickle. The fix is new pipe, not a new faucet.
A damp patch on a ceiling, a warm spot on the floor, a meter that keeps ticking with every tap off. A slow leak inside a wall does most of its damage before it ever shows itself.
One slow sink is a sink. Two slow drains on different floors are sharing the pipe out to the street, and a basement drain that gurgles while you run water upstairs is the main line talking.
After a heavy rain
Heavy rain finds the weak spots in a house’s plumbing. Four checks you can make yourself, then call us and we’ll look at the rest.
Clear water with no smell is usually groundwater. Gray water, or a sewer smell, means the main line is backing up: stop running water in the house and call us.
A main line with a cracked joint or roots in it can take in groundwater during a storm and slow down. A sewer camera inspection, $89 added to a visit, shows where.
If the house has one, watch it once: it should start as the pit fills, empty it and shut off. Our sump pump replacement page has the rest of the checks.
If floodwater got to a gas water heater’s burner or controls, leave it off. Don’t relight it until a plumber has checked it.
Call us after a storm and we’ll check it all: the floor drains, the main line, the sump pump and the water heater. Any repair gets its price in writing before the work starts.
Choosing a plumber
Questions worth asking anybody who comes out, us included.
In a Calverton house a water problem can belong to the plumber, the well contractor or the septic company. The plumber worth calling tells you when it’s a well pump or a full tank, instead of selling a repair that won’t fix it.
Anyone can check on the state’s license lookup in about a minute. It’s the one question that takes the guesswork out of the rest.
A sewer camera inspection is cheap next to any dig, and it shows whether the problem is a root, a sag or a break. A quote to dig without one is a guess.
Every plumbing job on our list has a range. A plumber who won’t say where yours lands until the wall’s open is asking for a blank check.

Tyson was wonderful; professional, very knowledgeable, thorough and fast. He was great at telling me about what was needed, and I very much appreciated that. For the next plumbing problem we have, I will have SwiftPro on speed dial.
Questions
Because no utility is pushing water at it. On a private well, the pressure is set by the well’s pressure switch and tank, so low or surging pressure usually traces back there, and that’s work for a well contractor. If only one fixture is weak, it’s more likely an aerator, a cartridge or a shutoff valve inside the house, which is ours.
It depends on the job, and every one has a published range: drain cleaning for one fixture $200 to $800, main sewer line cleaning $550 to $1,650, leak detection $200 to $500, a pressure reducing valve replacement $500 to $1,000, toilet repair $250 to $900. A sewer camera inspection added to a visit is $89.
