Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works
A sewer camera inspection is $89 added to a visit we’re already making. It’s the cheapest way to know what a drain is doing before anybody talks about digging.
With Comfort+ membership, any service is 15% off, and a water heater flush with a sewer camera inspection and a plumbing safety inspection comes every year.
What’s different in The Plains
Which side of the town line you’re on decides your water. The Town’s 124 homes, by the 2020 Census count, take FCWSA water and drain to FCWSA’s sewer. Past the line, the US Geological Survey says groundwater supplies every private household in Fauquier County, which here means a private well. Inside the house, the pipes, drains, fixtures and water heater are ours; the well, its pump and any septic system go to a well or septic contractor.
Freezes come early and leave late. NOAA’s 1991 to 2020 normals for its Warrenton 3 SE station, about 12 miles south, put the median first fall freeze near November 1 and the last spring one near April 9. Fauquier’s code sets frost depth at 24 inches, so buried lines sit below it; the pipes at risk run through a wall facing the wind, a vented crawlspace or the hose bibb. In early February 2026 a station labeled The Plains, a few miles north, logged wind chills of 6 below and 5 below. Wind can’t chill water below the air temperature, but drawn through a leaky wall it freezes a pipe faster.
Heavy rain is the other trouble. A flash flood on August 11, 2017 closed Old Tavern Road half a mile from town, and on September 9, 2023 standing water blocked roads near Marshall and The Plains; FEMA maps a Zone A flood hazard area within about 300 meters of the center of town. A sump pump that runs the whole storm while the water keeps creeping up the pit needs replacing, not watching, and one on house current stops when a falling tree takes the lines. Our sump pump replacement page has the set price, with a battery backup option.
In town, FCWSA’s 2026 schedule flushes The Plains system on May 27 and November 23, weather permitting. Expect weak pressure, air and discolored water for about six hours; run the cold tap until it clears. Grit from a flush can lodge in a toilet’s fill valve, and one that won’t seat runs all night, which mattered more this year with FCWSA under a Drought Warning as of June 2026. Toilet repair is $250 to $900.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
ZIP 20198 as a whole, the Town included: its own homes are too few for steady Census figures.
What you’d notice
That’s a frozen pipe until proven otherwise, usually in an outside wall or above a crawlspace. Open the faucet, warm the wall with a space heater or a hair dryer, and shut off the main if you see a split. A line that froze once will likely freeze again unless it’s moved or insulated.
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.
Your pipes, your paperwork
On FCWSA sewer, the service line from the main to the property line and the lateral from there to the house are the customer’s to clear. FCWSA clears its mains and fixes a service line under a public street, and it doesn’t reimburse a plumber. Source.
On FCWSA water (Bealeton, Catlett, Marshall, New Baltimore, Vint Hill and its other systems), FCWSA says it can’t guarantee uniform pressure, and that over 80 psi the customer should install a pressure regulating valve at their own expense. Homes on private wells aren’t covered by this. Source.

Choosing a plumber
Questions worth asking anybody who comes out, us included.
A torch inside a wall is how a frozen pipe becomes a house fire. Ask how they thaw a line, and what they’ll do so it doesn’t freeze there again.
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.
