The pump starts every time you rinse a dish
On a slow Philomont well, a pressure tank that’s too small or has lost its air shows up fast. Short cycling like that wears the motor, so it’s worth a call before the pump quits.

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 Philomont
Philomont’s wells keep getting deeper, and the newest ones run about 500 feet.
There’s no water main coming down the road to Philomont. Loudoun County’s well records show close to 1,300 active household wells within three miles of the village, with a median recorded depth of 400 feet. If you live here, the pump hanging in that hole is how every faucet, toilet and hose bib in the house gets water.
When your well went in says a lot about how deep it is. Philomont-area wells on record from the 1970s have a median around 265 feet. The 1980s ones, about 305. By the 2000s it was 400, and wells from the 2010s and 2020s sit near 500. Of the wells with a depth on file, 205 go to 600 feet or more. Every extra hundred feet is more wire, more pipe and more weight to bring up, so a pump swap on a newer, deeper well usually costs more than the same pump on a 1980s one.
Yield is the other half. About one in seven Philomont-area wells with a yield on record makes less than 3 gallons a minute, because Loudoun’s water comes from cracks in the bedrock and some holes hit fewer of them. A slow well and a small pressure tank make the pump start constantly. Amtrol, which builds the tanks, says a bigger tank means less running for the pump, so on a low-yield well we look hard at the tank before we look at the pump.
The houses span the decades too. In 20132, the Purcellville ZIP area that holds Philomont, about half the homes went up after 2000 and nearly a quarter before 1980. A 1970s farmhouse with a shallow well and a 2010s house with a deep one can sit on the same road and need entirely different parts.

When to call
When a well pump in Philomont needs a plumber.
The tank came with the house
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.
No gas main, no water main
Where most houses heat with propane or electricity, there’s usually no utility line running down the road at all, and the water comes from a well on the lot. That makes the pump the most important appliance in the house.
When the power goes out
When the power goes out in Philomont, so does the well.
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.
- 1
Fill up before the storm
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.
- 2
A generator needs a transfer switch
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.
- 3
Size the generator for the pump
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.
- 4
When the power comes back
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.
- 5
Under floodwater? Leave it off
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.
- 6
Test the water after well work
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
How to pick who works on your well pump in Philomont.
Questions to ask anybody who quotes you, us included.
Will they look at the tank size, not just the pump?
On a low-yield well the tank does a lot of the work. Ask whether they’ll check its size and air charge against your well before they talk you into a bigger pump.
Will they test before they pull the pump?
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.
Is the price in writing before anything comes out?
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
Well pump questions from Philomont.
How deep is my Philomont well likely to be?
It depends mostly on when it went in: around 265 feet for wells on record from the 1970s, about 400 for the 2000s and about 500 since. Your well’s own depth is often in the county’s well record, and it’s worth having before anyone quotes a pump.
I’ve never tested my Philomont well. Should I?
Yes, and you’d have company: 41 percent of people at Virginia’s 2021 well water clinics had never tested theirs. VCE Loudoun’s program sells a $70 kit through its 2027 waitlist. Test again a week or two after any pump work.
How much does well pump replacement cost in Philomont?
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.
Do I need a permit to replace a well pump in Virginia?
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.
