What’s different in Fairfax Station
Out here the first plumbing question is where the water starts and where it ends. Fairfax County’s Health Department shows active septic permits on about 3,000 properties with a Fairfax Station address and private well permits on about 1,700, and almost every one of those well houses drains to septic as well. Most sit west of Ox Road, along roads like Hampton, Henderson, Yates Ford and Wolf Run Shoals, where the county plans for one house per five to ten acres to protect the Occoquan and keeps much of the land outside the sewer area.
Crosspointe is the other Fairfax Station. Its 1990s streets barely register in either permit list, so those houses drain to the county sewer and drink Fairfax Water, and the county’s rules on the lateral and the pressure reducing valve, further down this page, are the ones that apply there.
A well house runs its own small water company in the basement: the pump down the well, a pressure tank, and a switch that decides when the pump runs. Those three belong to a well contractor. From the tank onward, the pipes, the fixtures, the water heater and every drain are plumbing, and that’s the part we work on. Tell us when you book whether the house is on a well; it changes what the tech checks first.
The houses themselves are mostly 1980s and 90s; about 8 in 10 homes in 22039 went up between 1980 and 1999. With four bedrooms or more in about 9 in 10 of them, supply runs are long, and a pinhole leak or a split fitting can sit above a finished basement ceiling for weeks before the drywall shows it.
Neighborhood by neighborhood
Census figures for each place, and the pipe that usually goes with houses that age. Median year built and heat count owner-occupied homes only.
| Place | Median home built | Most homes are | Heated with | The pipe you usually find |
|---|---|---|---|---|
| Fairfax Station | 1982 | single-family houses, about 9 in 10 | gas, about 5 in 10 | The polybutylene years: check the supply pipe; PVC drains. |
| South Run | 1988 | single-family houses, nearly all | gas, about 9 in 10 | The polybutylene years: check the supply pipe; PVC drains. |
| Crosspointe | 1993 | single-family houses, nearly all | gas, about 8 in 10 | The polybutylene years: check the supply pipe; PVC drains. |

What you’d notice
There’s no water meter to watch on a well, so listen instead. A pump that starts in the middle of the night with nobody using water means water is going somewhere: a toilet flapper, an outside hose bib, a supply line inside a wall. We find the hidden ones with leak detection, $200 to $500. If the house checks out dry, the loss is in the well system itself, and that’s the well contractor’s call.
Polybutylene, often stamped PB, went into houses from about 1978 to 1995. It tends to let go at the fittings with no warning, so it’s worth knowing whether you have it.
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
In Fairfax County the homeowner owns the whole sewer lateral, from the house to the county main, including the stretch under the street. Replacing it takes a county plumbing permit, plus a VDOT permit under a state road. Source.
Fairfax Water promises 20 psi at the main and no uniform pressure, and the pressure reducing valve on your side of the meter is yours to buy and keep up. Over 80 psi, the Virginia Residential Code calls for one, and an expansion tank with it. Source.
Our Virginia Class A contractor license, 2705192276, is on the side of the van.
Choosing a plumber
Questions worth asking anybody who comes out, us included.
In a big Fairfax Station house the supply lines often run above a finished basement ceiling. Ask whether the quote covers opening the ceiling and closing it again, or only the pipe, so the number you agree to is the number you pay.
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.

Questions
Fairfax County keeps septic permits by address in its PLUS system, along with the date the tank was last pumped, so a quick search settles it. As a rule of thumb, the big lots west of Ox Road are on septic and Crosspointe is on the county sewer.
No. Those are licensed septic and well contractors’ jobs in Fairfax County. We handle the plumbing between them: the drains and the line out to the tank, the supply side after the pressure tank, the water heater, and leaks anywhere inside. A sewer camera inspection, $89 on a visit we’re already making, shows whether a slow line is the pipe or the tank.
No. Both are about public systems: the lateral is the pipe from your house to the county sewer main, and the pressure valve rule is about water arriving from Fairfax Water’s mains. A house on a well and septic has neither; its pressure is set by the well’s own switch. In Crosspointe and the other neighborhoods on county sewer and Fairfax Water both apply, and a pressure reducing valve replacement runs $500 to $1,000.
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.
