Sump pump replacement, installed in your existing pit

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 Warrenton
Cellars the Town dug its sewers deep for, and builder basements out past the line.
Nobody counts Warrenton’s basements; the Census doesn’t ask. The Town’s utility design manual takes them for granted: where floor levels aren’t known yet, it sets a new sewer main deep enough to drain a cellar six feet below the street. Close to three in ten homes in town went up before 1960, and in the oldest of them the pit, if there is one, was most likely cut in later, wherever the water showed up, so we check its depth and walls before the new pump goes in.
The Town Code is plain about where that water may not go. Groundwater, subsurface drainage and roof runoff are barred from the sanitary sewer, and no downspout may be tied into it, so a sump hose run to a laundry tub or a floor drain has to come out. The usual answer is a line that ends on the lawn, pointed downhill and away from the foundation.
Not every pit in a Warrenton basement is a sump. The Code requires a drain that sits too low to reach the sewer by gravity to be lifted by a pump, so a basement bathroom or laundry below the sewer line drains to a sealed pit with a vent pipe: a sewage ejector. That’s its own job with its own written price. The $697 figure here is for a sump pump in a groundwater pit.
Out past the town limits, New Baltimore is almost entirely single-family houses, and close to half went up in 2000 or later, Brookside among them. A basement from those years often still has the pit the builder set. Brookside and Vint Hill drain to FCWSA’s sewer, and the Authority’s standards bar a sump pump from connecting to it, directly or indirectly. Where New Baltimore is on septic, the pump’s water belongs in the yard just the same, never in the tank.

New Baltimore only. It’s the one Census place on the county side with mostly Warrenton mail, so the farms and lots beyond it aren’t in these figures.

When it’s time
When a sump pump in Warrenton 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 Warrenton, 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

Questions to ask anybody who quotes you, us included.
Did they open the lid before quoting?
A sealed lid with a vent pipe, and a toilet or washer draining into it, means a sewage ejector, not a sump. Ask anyone quoting a sump pump replacement to look inside first, because the two are different pumps and different prices.
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 Warrenton.
I rent in the Town of Warrenton. Who replaces the sump pump?
The owner, as a rule, since the pump belongs to the house. Close to four households in ten inside the town limits rent. If it runs nonstop or not at all, tell your landlord now, and pass along that a replacement in the existing pit is $697 installed, with any extras priced in writing first.
Can my sump line empty into the storm drain at the street?
Footing and foundation drain water is allowed in the Town’s storm drainage system, but its code bars opening a connection into an inlet or catch basin without the town manager’s authorization, and washer or floor drain water may not go that way.
What should I check on my Warrenton sump pump after a big storm?
Warrenton gets the kind of rain that tests one. NOAA’s Storm Events Database has Lee Highway flooded and closed in town between Comfort Inn Drive and Dumfries Road in July 2017, and the Frytown Road bridge over Cedar Run, just east of town, under water in August 2018. After rain like that, look in the pit while the ground is still soaked: the pump should start, empty it and stop. Then find where its pipe ends outside and make sure the water heads downhill, away from the house. The Town’s own flood checklist tells residents to install check valves and to consider a sump pump with a battery. Call us when the rain stops and we’ll look over the pump, its float, the valve and the line. If it can’t keep up, a new one in the same pit is $697 installed, with anything extra priced in writing first.
How much does sump pump replacement cost in Warrenton?
$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.
