The $49 visit is waived when you go ahead with the repair. Pulling a pump just to look at it is $1,300 to $2,000, so we test the tank, the switch and the pump’s wire from the house first.
Replacing a pump needs no health department well permit in Virginia. We don’t drill or deepen wells; if yours needs that, we’ll tell you who to call.

What’s different in Bristow
About two thirds of Bristow’s land sits in the Census Bureau’s Linton Hall place, where three in four homes went up since 2000 and nearly nine in ten owner homes heat with gas. That’s subdivision country, Victory Lakes and Braemar among it. The other third of 20136 sits in no Census place, and it takes in Brentsville, the county seat from 1820 to 1893. No public record we’ve found says which Bristow addresses are on wells, so we won’t guess at a number. If there’s a pressure tank in your basement, this page is for you.
Prince William Water doesn’t make anyone hook up. An owner in an unserved part of the county who wants public water pays to run the line from the nearest main, plus availability fees. So a well on an older Bristow lot can stay a well for good, even with a subdivision’s mains a field away. That makes the pump, the tank and the switch worth keeping in shape rather than waiting on a hookup that won’t come cheap.
You’d have plenty of company. The County’s Sustainability Commission counts about 50,000 people in western and mid Prince William drinking from roughly 16,000 private wells, its 2026 figure. Every one of those has its own pump and its own tank, and none is on anybody’s maintenance schedule but the owner’s. On a well, a slow pressure loss or a pump that runs longer than it used to is the early warning; nobody else is watching for it.
Prince William Water’s own lab will test a private well’s water for a fee, even if you’ve never been its customer. After we’ve had the pump out, Virginia Cooperative Extension says to shock chlorinate the well and retest for bacteria one to two weeks later, so that’s the sample to send. If the test or the pump says the well itself is failing, that’s work for a drilling rig, and we’ll tell you who to call.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
When to call
A burst of air from the taps after the water sits overnight often points to a check valve that’s letting water drain back down the well, or a well running low. Either way the pump works harder to refill. Note when it happens and whether the tank gauge drops with nothing running, then call.
On a house built in the 2000s, the pressure tank, the switch and often the pump are the builder’s originals. A bladder tank lasts five to seven years on average, so many of these are on their second or third.
A pump that starts every few seconds usually means the pressure tank lost its air cushion. Every start wears the motor, so it’s worth a call this week, not next month.
When the power goes out
The Virginia Department of Health puts it simply: if your home is on a well, the pump won’t work when the power is out. Here’s what to do before, during and after.
When a big storm is coming, fill a few jugs and the bathtub. Once the pump stops, all you have is what’s left in the pressure tank, and toilets need water to flush.
Many well pumps run on 240 volts. Franklin Electric’s installation manual says a transfer switch must be used any time a generator backs up a well pump, and VDH says to have the hookup made by a licensed electrician.
Franklin’s minimum for a 1 horsepower two-wire pump is a 6 kW generator, and 4 kW for a 1 horsepower three-wire pump. Not sure which yours is? The control box on the wall in the basement means three-wire.
Give the pump a minute to refill the tank. No water? Look at the well pump’s breaker. A surge can also take out the pressure switch or the control box, which we can test from the house.
VDH says to treat a well that was under floodwater as contaminated, and not to run the pump until its wiring is dry. Then shock chlorinate the well and test the water one to two weeks later.
Virginia Cooperative Extension recommends shock chlorinating after any repair to a well system, then a bacteria test one to two weeks later. A well’s water is the owner’s to look after: the EPA doesn’t regulate private wells.
Power back and still no water? Check the breaker, then call us. We’ll test the switch, the control box and the pump from the house before anything comes out of the well.

Choosing who works on it
Questions to ask anybody who quotes you, us included.
In Bristow it isn’t a given either way, so a good dispatcher asks. Someone who shows up expecting a city water meter and finds a pressure tank in the basement is starting from zero. Say so when you book, and mention what the gauge reads.
Pulling a pump is the expensive part of the job. Ask whether they check the tank’s air charge, the pressure switch and the pump’s amp draw and wire from the house first, so you don’t pay to pull a pump that was fine.
Ask for the part that failed and its price, written down, before the pump comes up. If the price can change once the pump is out, ask what would change it, like worn wire or a bad pitless adapter.

Questions
Maybe, but it isn’t quick or cheap. Prince William Water says owners in unserved areas pay to extend lines from the nearest main, plus availability fees. Ask the utility for that number. If the well is sound, fixing the pump is usually the faster way to get water back today.
Start with the tank and the pressure switch. On a well system that’s about twenty years old, both have usually been changed at least once, or should have been. The pump may still be the original. We test all three before recommending anything, and you get each price in writing.
A new submersible pump on your existing pipe and wire runs $2,781 to $4,000 installed, and with new wire and drop pipe it’s $4,900 to $6,500. A pressure tank alone is $2,200 to $2,950 and a pressure switch is $450 to $609. You get the number in writing before we pull anything.
Not a well permit. Virginia’s private well rules say replacing a pump, or a well cap or seal with an equivalent one, isn’t a well alteration. Building, deepening or abandoning a well does need a health department construction permit.
