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 Waterford
A county study put the high point of the village at about 472 feet near Waterford Elementary and the low point at about 340 feet, down at Catoctin Creek, so the whole village leans toward the water. In ZIP 20197, 98 percent of the housing is detached, so a pit here sits under a single-family house on its own lot. Houses lower on that slope tend to be the ones asking the most of a pump, and the median owner home dates to 1996, which puts an original pump near thirty years old.
Catoctin Creek has risen past its 8 foot flood stage at Waterford more than once. It crested at 10.07 feet in September 2015 and 9.78 feet in September 2018. In August 2020 it reached 11.11 feet, Route 662 flooded and water approached a building on Main Street. In December 2022 it hit 8.75 feet after two to three inches of rain. Those figures measure the creek, not your pit, but they show how much water this valley has had to shed.
A sump pump runs on house power, and the storms that fill a pit are the ones that take power out. Winds estimated at about 76 mph in the June 2012 derecho snapped trees along Thicket Court. In July 2024 and again in July 2025, thunderstorm gusts brought trees down around the village. A battery backup is one of the extras, and a pump with a backup installed together is $3,200. If a wet basement would cost you more than the backup does, price the pair together.
Sump water belongs outdoors, not in a sewer line, communal or otherwise, and the village’s communal sewer dates to 1975. Waterford homes drink from private wells, which is a separate system from the pit. With so many detached houses, the discharge usually has a yard to cross on its way out. Whoever replaces the pump should look at where that pipe ends: the line outside is one of the extras, and you should see its price before the shovel comes out.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
ZIP 20197 as a whole: every Waterford address, the village included. The Census place for the village alone has too few homes for steady figures.
When it’s time
In a valley where the creek topped flood stage in 2015, 2018, 2020 and 2022, a pit can keep filling for a while after the sky clears. A pump that cycles for hours, hums without moving water, or has a float that sticks is the one to replace before the next heavy rain. Listen from the lid and keep your hands out of the pit.
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.
Ask whether the new pump uses your current discharge line or needs a new one, and who pays for the digging if it does. A plumber who knows the village will also ask where the pipe comes out of the house, because in the Waterford Historic District an outside change can need the review committee’s say first.
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
No. The well pump feeds your taps; the sump pump empties a pit. The county’s study found that Waterford homes rely on private wells, and wells are not our work, but the pit and its pump are.
A new pump in an existing pit is work inside the house, so the district’s review of exterior changes does not come into it. A new discharge line, or an exit moved to a different wall, is the part to raise with the County Historic District Review Committee, which approves most exterior changes in the central village before work starts.

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.
