Why is my well running out of water?
Your well running out of water is a bad moment, and it almost always has a fixable cause. Most of these calls are not a dry aquifer. The answer is usually the equipment, or a water level that fell below the pump.
Here are the causes in the order we find them on South Jersey service calls. Each one has its own tell, its own fix, and its own cost.
Sudden loss of water is almost always the pump
When water stops all at once, the well is rarely the reason. Wells fade over hours or days. Equipment quits in a second.
Start at the breaker and the pressure gauge. A tripped well breaker, a dead pressure switch, or a burnt pump motor all read the same at the tap. Most submersibles run 10 to 15 years, and our acidic groundwater tends to shorten that.
A waterlogged pressure tank can look like a dry well too. The bladder tears, the pump short cycles, and you get a few seconds of water at a time. A leaking check valve drains the drop pipe back into the well. The first minute at the tap is air.
The first call is our well pump repair service. We test the pump, the switch, the tank, and the wiring before anyone talks about drilling. National cost guides put most well pump repairs between about $350 and $1,500, and our estimates are free.
If water still runs but comes out weak, you have a different list to work through. That one is here: why well water pressure gets low.
The pump may be sitting above the water
A pump can only move water it can reach. If the level in the well drops below the pump intake, the pump pulls air. The house goes dry while water is still down there.
Levels drop for plain reasons. A dry summer, a hot week of sprinklers, and heavy irrigation nearby all pull on the same shallow water. Most mainland wells here draw from the Kirkwood-Cohansey sands. Those sands are shallow, productive and unconfined, so the water table moves with the weather.
The weather has been dry. NJDEP declared a statewide Drought Warning on December 5, 2025, after a Drought Watch that October. Its August 20, 2026 update says indicators are improving with summer rain. Deficits from two years of below average precipitation are not yet overcome statewide, particularly for streamflow and unconfined groundwater.
Cape May County reads differently. Wells there go into deeper confined sands, such as the Atlantic City 800 foot sand. A dry summer moves them less. Heavy pumping near the coast can pull salt water toward fresh wells. Well work in Cape May County gets planned around that risk.
When the water is lower but still good, the fix is pump placement. We lower the pump on longer drop pipe and leave a margin above the bottom of the well. That is a pump service visit rather than a drilling job.
A low yield well runs out, then comes back
Some wells hold water but give it up slowly. The house draws faster than the sand can feed the hole. You run out during laundry or evening showers, and the water is back by morning.
That pattern points at yield rather than a broken part. Every well has a recovery rate, measured in gallons a minute. We measure flow and yield while drilling, and an existing well can be tested the same way.
Two fixes work here. The first is spreading out demand. Run laundry and dishes at separate hours, and water the lawn at night. The second is storage. A bigger pressure tank buys minutes, and a storage tank buys hours.
Tank sizing is pump and pressure tank work. A storage tank with a booster pump is a whole water system installation. Pressure tank replacement runs a few hundred to about $1,600 installed. The estimate for your house is free.
When the well itself is finished
Some wells are old, shallow, and done. The sand around the intake no longer gives what a modern house uses, and no pump setting changes that.
When that is the answer, we drill a replacement well to a better producing zone on the property. We site it, pull the NJDEP permit, then drill, case and grout it. We test the yield before the pump goes in. That is the same well drilling in Vineland and South Jersey work our rig does every week.
The old well does not stay open in the ground. State rules have a licensed driller seal it with grout. The grout goes in by tremie from the bottom up. That job is sealing an old well to NJDEP standards.
Published national figures run about fifteen to thirty dollars a foot. Complete wells often land between a few thousand and twelve thousand dollars. Depth and the target zone drive the number, so the estimate for your address is free.
What you can safely check
- Read the pressure gauge. Zero with the breaker on points at power, prime, or a leak.
- Check the well breaker. Reset it one time, and if it trips again leave it off.
- Listen at the tank or the well cap. A pump that runs without building pressure is a warning.
- Note the clock. Write down the time the water quit and the time it came back.
- Note what was running. Sprinklers, laundry, a pool fill, and a big draw next door all count.
- Stop drawing water once the taps sputter. A pump running dry can burn out in minutes.
That last step saves the most money. Air at the tap means the pump may be running with nothing to cool it. Shut the well breaker off and let the level come back while you wait for us.
Two jobs stay off your list. The pressure switch cover carries 230 volts any time the breaker is on. Pulling a pump takes a truck and rigging, and both jobs belong to a licensed pump installer.
Who is allowed to do well work in New Jersey
New Jersey keeps this work in licensed hands. Only licensed well drillers and licensed pump installers may install, service or decommission wells and pumps. The state counts about 530 licensed well drillers and about 150 licensed pump installers.
Paperwork comes before the drill. NJDEP requires a well permit before a well is drilled, constructed or physically altered. Only a licensed New Jersey well driller can obtain that permit. The state issues about 20,000 well permits a year.
We pull the permit on every job. The driller files the well record after construction, and files a decommissioning report when an old well is sealed. Those records stay with the property for the next buyer.
Where to start when the water quits
Start with the equipment and the clock. The gauge reading, the breaker, and the hour water returned tell us most of it.
Call (856) 207-7373 and describe what happened and when. We run service across Gloucester, Cumberland, Salem, Atlantic, Camden and Cape May counties, and no water calls are answered 24/7.
