What it costs
The same price as our sump pump replacement page: one flat number for a new pump in a pit that’s still sound, with what costs extra named right beside it.
Sump pump replacement, installed in your existing pit

Priced in writing before we start
Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works
$697 covers a new cast iron pump, a quiet check valve, new PVC up to your existing discharge line, a battery water alarm by the pit, the old pump hauled away and a bucket test before we leave.
A battery backup keeps pumping through a power outage, and the outage usually comes with the storm. With a new pump, the pair is $3,200 installed. The sump pump estimator helps you decide whether you need one.
What’s different in Broad Run
FEMA maps a Zone A special flood hazard area within a few hundred yards of the hamlet’s map point. A flash flood on September 9, 2023 left standing water on roads near Marshall and The Plains, and NCEI’s record of it begins at Broad Run. On January 9 and 10, 2024, high water closed Georgetown Road near Brookland Drive. A pit in a house near that water has to move whatever the footing drain sends it.
Snow does it slower. On February 12 and 13, 2014, a volunteer gauge about three miles south-southwest of the village logged 14 inches of snow holding 4.20 inches of water. Fauquier County puts frost depth at 24 inches, so a melt can run across frozen ground, and what can’t soak in heads for the footing drain. A pump that sat idle all summer has a long wet season ahead.
Hurricane Sandy on October 29, 2012 left forty roads blocked across Northern Fauquier by trees or power lines, and the March 2, 2018 nor’easter set off a wave of calls to Fauquier County 911 for trees and wires down. On August 11, 2017 a tornado dropped trees on lines and homes beside John Marshall Highway. Heavy rain and a dead circuit can arrive together, which is the case for a battery backup. A pump with one installed runs $3,200.
The discharge pipe decides whether the pump’s work holds. Outside the public water and sewer areas, the Fauquier County Health Department permits wells and septic systems, and on a lot with a well and a septic field the discharge should end well away from both. Follow your line to its end: a pipe that dumps beside the wall sends the water back to the pit.
By the numbers

When it’s time
After a thaw or a long rain, a pump that cycles every few minutes is often keeping up with a footing drain that’s still delivering. A pump that runs with the pit nearly dry, hums without moving water, or stays on after the float drops is on its way out.
Zoeller, who make a lot of the pumps around here, puts a sump pump’s life at seven to ten years. Past seven, replace it on your schedule instead of the storm’s.
Water is running back into the pit through a check valve that no longer closes, so the pump moves the same water again and again until it wears out.
After a heavy rain
Six checks you can make yourself once the rain lets up, none of them with your hands in the pit. Then call us and we’ll check it all.
Watch the pit during the rain or right after. The pump should start as the water rises, empty the pit and shut off. A full pit, or a pump that hums and moves nothing, isn’t keeping up.
Walk the basement: the corners, the walls, the floor by the pit, under the water heater and the furnace. Photograph any wet spot before you mop, so we can see where it came in.
Outside, find where the pump’s pipe ends. It should be open, not crushed, buried or full of leaves, and aimed away from the house so the water doesn’t run back to the foundation.
Listen when the pump shuts off. Water rushing back into the pit means the check valve isn’t closing, and the pump has to move that water again.
The pump stops when the power does, often at the height of the storm. If the basement took water during an outage, that’s the job a battery backup does.
If water is standing near the pit, an outlet or anything plugged in, don’t wade in to check. Call us, and only switch the power off at the panel from somewhere dry.
Not sure what you saw? Call us after a storm and we’ll check it all: the pump, the float, the check valve, the discharge line and where the water came in. If the pump can’t keep up, a new one is $697 installed in your existing pit; a new or deeper pit, a battery backup, discharge line work outside and a dedicated circuit are extra, priced in writing before we start.
Choosing who replaces it
Questions to ask anybody who quotes you, us included.
A replacement should end with a test: water poured in until the float lifts, the pump emptying the pit, the check valve holding. Ask for anything extra in writing: a new or deeper pit, discharge work outside, a battery backup or a dedicated circuit. The sump pump replacement page lists them.
Ask what the number covers: the pump, the check valve, the pipe, hauling the old one off, a test before they leave. Then ask what costs extra, and get it in writing.
Cast iron, ideally. Plastic pumps cost less and are usually the ones that quit early. Ask before the old one comes out.
A discharge line that’s cracked, buried or frozen shut every January leaves the new pump pushing against a closed pipe. Whoever replaces it should check the outside end too.

Questions
If it shares a breaker with a freezer or a washer, a storm is when that breaker trips. A dedicated circuit is priced as an extra, in writing, before the work starts. Ask the plumber to look at what the pump is plugged into.
Maybe not. A pump moves water out of the pit; it can’t stop water coming through a crack, a window well or a wall. If the pit overflowed, the pump was stopped, too small or without power. The visit checks the float, the check valve and the discharge before a replacement is priced.

Yes. Pour five gallons of water into the pit. The float should rise, the pump should start within a few seconds, and it should shut off clean once the water’s down. If you hear water rushing back into the pit after it stops, that’s the check valve.
