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 Haymarket
Inside the Town of Haymarket, the Town lists Prince William Water for water and sewer, so a house off Washington Street has a meter, not a well pump. Dominion Valley is on the utility’s Haymarket system, fed from surface water. Up on Bull Run Mountain and around Evergreen it’s another world. Prince William Water serves its customers there from its own wells, a separate system that by permit can’t tie into the Gainesville and Haymarket mains, and the utility’s own notes speak to the private wells beside them.
Those notes are worth a read if your well is up there. The utility has run the mountain’s wells since 1990, and of the 14 it originally bought, only six are still in use. It also says the aquifers under the mountain and Evergreen are regional and connected, so every well drawing from them has some effect, however small, on the others. For a private well, that means what it yields can change over the years without anything in the house breaking.
The houses up there are older than the rest of Haymarket. In the Census Bureau’s Bull Run Mountain Estates place the median owner home dates to 1978 and close to half went up in the 1970s, while Haymarket mail as a whole has a median of 2006. A well from the 1970s has often been through a couple of pumps, and the newest pump may be hanging on the oldest wire. When one comes up we test the wire too, and replacing both at once is the $4,900 to $6,500 row.
Prince William Water is upgrading the mountain’s well system, with construction expected to start in fall 2026. Nobody has to connect, though anyone on the mountain or in Evergreen can apply. If you’re weighing a switch, that’s a conversation with the utility. If you’re keeping your own well, the pump, the tank and the switch stay yours to look after, and we’ll keep them working.
Neighborhood by neighborhood
Census figures for the owner-occupied homes in each place, and what to look at first on a well system in houses that age.
| Place | Median home built | Most homes are | Heated with | What to look at first |
|---|---|---|---|---|
| Bull Run Mountain Estates | 1978 | single-family houses, nearly all | electricity, about 4 in 10 | The well’s depth and what’s been replaced before. |
| Haymarket | 1995 | single-family houses, about 6 in 10 | gas, about 6 in 10 | The tank first, then the pump’s age and wire. |
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
Inside the town limits only, about one in eighteen of the owner homes with Haymarket mail. Dominion Valley, Piedmont and Bull Run Mountain Estates sit outside it, in the county.

When to call
On the mountain, where wells share one aquifer and yields drift, a pump that spits air or quits after heavy use and comes back after a rest may be outrunning the well. We test the pump’s draw and the switch before calling it a pump failure. If the well needs deepening, we’ll tell you who has the rig.
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.
A plumber who asks for your street before quoting is asking the right thing. In the Town or Dominion Valley a pressure problem starts on the utility side. On Bull Run Mountain you might be a utility customer or on a private well, and the first test is completely different.
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
No. The utility says no one there is required to become a customer or connect, though every resident on the mountain or in Evergreen can apply. A private well with a sound pump and tank keeps working fine on its own, and the choice stays yours.
The utility says the project is designed to eliminate or greatly reduce any effect on nearby wells, and it sets pumping rates from its tests. It also says it can’t prove no effect unless private owners let it monitor their wells during pumping tests. If your pressure changes, note when it started and call.
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.
