It keeps running days after the rain stops
On flat, slow-draining ground that’s normal for a day or two. A pump cycling every minute with the pit nearly dry, or never catching up as the water nears the rim, needs replacing before the next storm.

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 Catlett
Catlett basements sit on flat ground beside Cedar Run’s floodplain.
Nobody publishes a count of Catlett basements; the Census doesn’t ask. It does show a ZIP of detached houses only, 1,415 of them, with the 1990s the busiest decade at about 270 homes. A basement from then usually has a pit poured with the slab and, by now, a pump that isn’t the builder’s. The 180 or so homes from before 1940 may have a cellar, with any pit added later.
The County calls the Culpeper Basin under Catlett nearly flat, and the “blackjack” soils that ruined drainfields here for decades are tight. Soil that won’t take a septic field’s water usually doesn’t take rain quickly either, so water beside a foundation waits for the footing drain to carry it to the pump.
The National Weather Service’s gauge on Cedar Run near Catlett puts minor flooding at 15 feet, when water nears a low spot on Flatwood Lane; at 21 feet the Route 806 bridge floods and water gets into buildings nearby. The creek reached 18.2 feet in July 2013, when flash flooding closed roads in Catlett, and 15.91 feet in July 2025 on the preliminary reading. In November 2020 flooding closed Elk Run Road near Tenerife Road.
A sump pump has limits there. It keeps groundwater rising under the floor from becoming a wet basement; it can’t hold back a creek coming in over the ground. Once floodwater drops, a pump that ran for hours or sat underwater deserves a test.

When it’s time
When a sump pump in Catlett needs replacing.
It’s past seven years old
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.
It starts, stops, then starts again
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
After a storm in Catlett, check the sump pump.
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.
- 1
Does the pump kick on?
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.
- 2
Is there water where it shouldn’t be?
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.
- 3
Is the discharge line clear?
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.
- 4
Does the check valve hold?
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.
- 5
Did the power go out?
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.
- 6
Water near an outlet? Stay out.
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
How to pick the best plumber for a sump pump in Catlett.
Questions to ask anybody who quotes you, us included.
Did they ask whether you’re on a STEP tank or a septic field?
Neither should ever take sump water, and a plumber who doesn’t ask may tie the discharge into the nearest floor drain.
Is the price for the whole job?
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.
What’s the new pump made of?
Cast iron, ideally. Plastic pumps cost less and are usually the ones that quit early. Ask before the old one comes out.
Do they look at where the water goes?
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
Sump pump questions from Catlett.
Can the sump pump drain to a floor drain on the County sewer?
No. The County’s STEP guide names roof drains and floor drains among the connections it prohibits and asks owners to keep rainwater out. Sump water goes outside, well clear of the house and the tank.
Does the County’s operator take care of my sump pump?
No. The operator keeps up the County’s STEP tank, its pump and its panel. Under the County’s sewer ordinance everything else on the lot is the owner’s, the sump pump included, along with the power both pumps run on.
What should I check after a storm in Catlett?
Power first: wind is the other half of Catlett’s storm record. NOAA logs gusts estimated at 75 mph in August 2021 that downed trees on Old Dumfries Road, and the March 2018 windstorm swamped Fauquier’s 911 center with calls about trees and wires down. With the power out, the sump stops, and so does a STEP tank’s pump, so go easy on water. Once it’s back, check that the sump restarts and the STEP panel is quiet; an alarm is the County operator’s, at 540-325-0748. Then call us to check the pump, the float and the check valve. If it can’t keep up, a new one is $697 installed, or $3,200 with a battery backup.
How much does sump pump replacement cost in Catlett?
$697 installed in your existing pit: a new cast iron pump, a quiet check valve, new PVC to your discharge line, a battery water alarm, the old pump hauled away and a bucket test. A new or deeper pit, discharge line work outside, a battery backup and a dedicated circuit are extra, priced in writing before we start. A new pump and a battery backup installed together are $3,200.
Can I check my sump pump myself?
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.
