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.

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 Casanova
NOAA’s storm database holds four flood reports within two miles of Casanova: a creek out of its banks along Meetze Road in December 2011, high water over a bridge on Rogues Road in May 2014, Rogues Road closed in November 2020, and a foot of water across Balls Mill Road in July 2025. FEMA maps the village point as minimal flood hazard, but a flood map and a wet footing are two different questions.
USGS’s groundwater study of Fauquier finds higher levels in the southeastern basin, where Casanova sits on the Turkey Run Formation, than in the crystalline northwest. The Plains station, 16.5 miles north, logs about 46 inches of precipitation a year in its normals. A sump pit is where footing water goes when the ground can’t hold it, so a pump here should be tested before the wet months, not during them.
A house with a well and a sump pit runs two pumps off one supply of power. When the lines come down, both stop together: the taps, then the pit. On August 13, 2021, 60 knot gusts put numerous trees down at Casanova Road and Meetze Road, the kind of blow that takes lines with it. A battery backup keeps the sump pump going through an outage; the well pump is a separate matter.
Septic changes where the discharge can go. Water pumped onto the drain field takes up room the field needs for the house’s own wastewater, so the outlet belongs on ground that isn’t the field. Cold is the other test of the outlet. Warrenton 3 SE sees about 98 nights a year at 32 or below, and Fauquier County figures frost at 24 inches down, so any stretch of pipe above that depth can ice over. A pump pushing against a plug of ice trips out or burns out.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
Casanova’s own ZIP, 20139, is post office boxes only, so the Census Bureau maps no area for it. These are ZIP 20119 as a whole, the Catlett ZIP area Casanova sits in.
When it’s time
In a basin where groundwater runs higher, a pump that keeps cycling for a while after a storm is often doing its job. One that hums with the water still rising, or doesn’t start, is failing. Don’t reach into the pit to find out; call us.
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.
On a septic lot the outlet can matter as much as the pump. Ask the plumber to follow the pipe from the pit to the spot where the water comes out, and to tell you if that spot is on or near the drain field. Rerouting the outlet is outside plumbing, priced separately in writing before any digging.
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.

Tech was super knowledgeable, polite, communicative, and kind. I highly recommend this great company who prioritized my request to review my sump pump and other related needs
Questions
No. The battery backup runs the sump pump alone, and the well pump stops with the grid, taps included. Pump and backup together come to $3,200. A new or deeper pit, drain work outside and a dedicated circuit each sit outside that number.
About one occupied home in five in ZIP 20119 is rented. The pit and pump belong to the house, so the owner is the one to ask first. Tell them what you have noticed: a pump that hums without moving water, or one that cycles for days after rain.

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.
