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
$697
Sump pump and battery backup, installed together
$3,200
or $53/mo at 0% APR for 60 months
A new or deeper pit, discharge line work outside, or a dedicated circuit
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 Purcellville
Inside the town limits the Town Code is plain: nobody may send groundwater, surface water, roof runoff or subsurface drainage into the sanitary sewer, and a sump pump moves exactly that water. The code sends it to a storm sewer or a natural outlet, which for a house usually means a discharge line out to the yard, away from the foundation. A pump piped into a floor drain or a laundry tub has to change when it’s replaced.
The Town has its reasons. In the wet spring of 2018, rain getting into its sewer pushed the flow into the Basham Simms plant to as much as 3 million gallons a day, more than twice what the plant was built for. A sump tied into a house drain adds to every surge like that.
Where a house sits on the soil named for the town, the ground is on your side: Purcellville silty clay loam, mapped in Loudoun County in 2004, is very deep and well drained by the USDA’s description. Rain on ground like that tends to soak down instead of standing against a basement wall. So a Purcellville pump that runs hard usually has a local reason: a lot on low ground near the South Fork of Catoctin Creek, a downspout emptying beside the foundation, or a discharge that ends so close to the house the pump lifts the same water twice.
Outside the limits, on the farm and estate lots of 20132, about 96 in 100 homes are single-family houses, most on their own well and septic system. Virginia’s sewage regulations bar basement sump discharge, floor drains and footing drains from the septic system and say to direct that water away from the drainfield, so it can’t flow into, through or over it. We don’t work on wells or septic, but the pump in the basement is ours: $697 installed in the pit that’s there.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
Inside the town limits: the downtown grid around Main and 21st Streets, the historic corridors along Main, 21st, 23rd and 32nd Streets and Berlin Turnpike, and the newer neighborhoods such as Village Case.
When it’s time
In March 2026 the Town eased its water restrictions but stayed at the Drought Warning level, and well-drained ground in a dry spell sends little water to a pit. A pump that keeps cycling anyway is probably moving water the house made itself: a dehumidifier or a condensate line draining into the pit. Follow the pipes that end over it.
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.
In Purcellville the answer decides which rule the discharge line answers to: the Town Code on Town sewer, the state’s septic regulations on a tank. Either way the water goes outdoors, and on a septic lot it has to point away from the drainfield.
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
On a well, an outage shuts off two pumps at once: the well’s, so the house has no water, and the sump’s, while the pit keeps filling. A battery backup carries the sump until the power is back. The well is a well company’s job; the sump and its backup are ours.
Away from the house and clear of the drainfield, never across it. Find the field before deciding where the pipe ends. Outside line work is priced in writing before we start.
Start with the low ground along the South Fork of Catoctin Creek. NOAA’s Storm Events Database has the creek flooding in Purcellville in May 2014, and two to three feet of its water over Allder School Road in January 2013. FEMA maps a special flood hazard area along it, and the Town’s plan says nothing should be built in its floodway or 100-year floodplain. If your house sits on the low ground near it, look at the pit after every big storm. Once the rain stops, check that the pump ran, emptied the pit and stopped, that the basement walls are dry, and that the discharge runs away from the house. Then call us and we’ll check it all. A pump that can’t keep up is $697 to replace in the pit you have, with any extras priced in writing first.

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.
