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 Vienna
Vienna has two water stories. Inside the Town of Vienna, the Town sells water it buys from Fairfax Water and the Washington Aqueduct, and the Health Department’s records show just 28 active wells in all of 22180, the ZIP nearly the whole town sits in. Step onto the county side and the count jumps: 519 in 22181 and 471 in 22182. Those are permit records, so some are irrigation wells or lots that later tied into a main, but they bunch up right where the lots get big.
The street names tell you where. In 22181 the most records sit on Lawyers Road, Woodrow Street, Hunter Mill Road and Stryker Avenue, and around Hunters Crest Way and Hunter Station Road. In 22182 it’s Crowell Road and Beulah Road first, then Hunter Mill again and the Leesburg Pike side. About a third of the permits in each ZIP date to the 1960s, older than a lot of the subdivisions that filled in around them, so a well house here can share a road with neighbors who have never seen a pressure tank.
That changes the call. A neighbor on Town water phones about a leak at the meter; you phone about a pump that won’t quit. If you just bought on the county side and the listing said public water, go look before you trust it. A tall tank with a gauge and a switch on the pipe beside it settles the question. And if your street gets Town water from outside the line, as about a third of the Town’s connections do, the pump isn’t your problem at all.
In October 2026 a member’s yearly plumbing inspection in 22181 found a well pressure tank 14 years old, with the gauge on its tee kit waterlogged. That’s about twice the five to seven years Washington State’s health department gives a bladder tank on average. We laid out the two ways forward: a new pump safety switch and tee kit on the old tank, or a midsize tank along with them. When a tank has outlived its average by that much, the second one is what we’d pick for our own basement.
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.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
Nearly the whole town sits in 22180, which it shares with county streets toward Dunn Loring and Merrifield.
Vienna mail outside the town line: Wolf Trap and the Tysons edge in 22182, the Oakton side of 22181, Dunn Loring. The figures are Wolf Trap’s, the biggest piece.
When to call
On the county side of Vienna a well house and a Town water house can share a fence. If your pressure fades and the neighbors’ doesn’t, it isn’t the main. It’s your switch, your tank or your pump, and that’s ours to test.
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.
Say it when you book. A plumber who arrives expecting a water meter and finds a pressure tank has to start over. Tell whoever you call it’s a well, roughly how old the tank is, and what its 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
Yes. Plenty of county-side houses kept the well they were built with, and the Health Department lists close to a thousand active well records across 22181 and 22182. A Town water bill in your own name means you’re on its main. A pressure tank in your basement means a well, and some of those records are wells kept just for the yard.
Once a year is easy if you’re a member, since the yearly plumbing inspection already puts someone in your basement. We read the gauge, watch the pump cycle and check the air charge, which Amtrol sets 2 psi below the switch’s cut-in. That’s how a 14 year old tank gets caught before it starts wearing out the pump.
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.
