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 McLean
Most of McLean gets Fairfax Water, much of it treated by the Washington Aqueduct, and a big share of the homes in its two ZIPs are apartments and condos around Tysons. So it surprises people that the Health Department still lists 758 active well records in 22102 and 275 in 22101. They aren’t spread around. In 22102 they crowd the Great Falls side: Old Dominion Drive has the most, then Towlston Road, Georgetown Pike and Bellview Road. In 22101 it’s Turkey Run Road and Dulany Drive.
Those lots can hide deep wells. In September 2026 we were called to a McLean house that had been out of water for about two weeks. The well was 600 feet deep and ran on a control box with no pressure switch, and the box was flashing a fault code. A pump that far down means 600 feet of wire and drop pipe coming up and going back, which is why a deep well prices on its own row, $9,500 to $16,500, and why we test everything we can from the house before anyone starts pulling.
The well isn’t only the pump, either. In August 2026 a McLean owner had us repipe the horizontal water lines in the basement and crawl space, from the well pump out to the risers that feed the fixtures, in type L copper. On a well house that run from the tank is where every faucet’s water starts, so when it’s tired, the whole house feels it, and it’s worth a look whenever the pump or tank is being worked on.
McLean’s well permits are newer than you’d guess, too. About a quarter of the active records in 22102 were issued in 2000 or later, a bigger share than in Clifton or Fairfax Station. On lots this size that can mean a replacement well, a deeper one, or a second well for irrigation. Knowing when yours went in and how deep it goes is half the diagnosis, so dig out the paperwork if the house came with any.
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 |
|---|---|---|---|---|
| McLean | 1977 | single-family houses, about 8 in 10 | gas, about 7 in 10 | The well’s depth and what’s been replaced before. |
| Tysons | 1985 | condo and apartment buildings, about 7 in 10 | electricity, about 5 in 10 | The tank first, then the pump’s age and wire. |
By the numbers

When to call
Deep McLean wells often run a three-wire pump with a control box on the basement wall, and some, like the 600 foot well we saw in September, run on a box with no pressure switch at all. When that box shows an error code, write it down before you reset anything. It tells us where to start.
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.
Check the well pump’s breaker first. If it tripped once, reset it once. If it trips again, leave it off: the pump, its wire or the switch needs testing.
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.
Who keeps the well records
Fairfax County’s Health Department says every private well owner should test the water yearly for bacteria and chemicals, and that contamination can get in when the pump or plumbing is repaired. Source.

Choosing who works on it
Questions to ask anybody who quotes you, us included.
Ask how deep they think the well is and what the wire and pipe cost at that depth, in writing. On a shallow well the pump is most of the bill. On a deep one the pull, the wire and the drop pipe can be most of it.
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.

“Tyson came out to diagnose our well system and did so with ease! Within no time he had it figured out and provided a solution for us. Very reasonable pricing, phenomenal quality of work and knowledge can’t be beat!”

Questions
Start with whatever came with the house: drilling paperwork, a home inspection, or a receipt from whoever last pulled the pump. The Health Department keeps a permit record for each well parcel too. If nobody knows, we’ll explain how the pull is priced before we start, and the depth stops being a mystery the day the pump comes up.
No. We don’t drill or deepen wells. If the pump tests fine and the well itself has quit giving water, that’s a drilling rig, and we’ll tell you who to call. A lot of no-water calls turn out to be the pump, its wire, the switch or the control box, and those are ours.
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.
