Signs Your Well Is Running Dry (and What to Do First)

TL;DR: A well that's running dry rarely fails without warning. Air in the pipes, gritty or muddy water, a pump that cycles on and off every few minutes, and a static water level that's dropped more than a few feet from last year are the four biggest tells. Test your static water level with a well sounder or call a local driller for a $75-$150 inspection before you're stuck hauling water.

Your faucet sputters, spits air, then runs weak for a few seconds before going back to normal. If that's happening more often, your well isn't broken yet, but it's telling you something about the water table underneath your property.

Okoniq Property Hub helps owners log well readings, pump service dates, and water test results in one place so you're not guessing when the last inspection happened.

What are the first signs a well is running low?

The earliest sign is usually air in the line, not a total loss of water. You'll hear sputtering at the faucet, see cloudy or bubbly water for a few seconds, or notice the pressure drop then recover on its own. This happens because the pump intake is briefly exposed to air as the water level dips below it during heavy use.

A second early sign is your pump running more often but for shorter bursts, called short-cycling. Instead of running for 2-3 minutes and shutting off, it might kick on every 30-60 seconds. That's the pressure switch reacting to a well that can't keep up with demand, similar to how signs of a slab leak under your floor show up as unexplained pressure drops before any visible water damage appears.

Sandy or gritty water is another tell. As the water table drops, the pump starts pulling from lower in the well casing where sediment settles. If you're straining sand out of your faucet aerators more than once a season, that's not a fluke.

How do you check your well's static water level?

You check it by lowering a well sounder or a weighted string down the well casing and measuring where the water starts, then comparing that number to last year's reading. Most private wells have a static water level that fluctuates seasonally, dropping in late summer and recovering after fall or spring rain. A drop of 5-10 feet from one year to the next during the same season is worth watching. A drop of 20 feet or more, or a level that's now within a few feet of the pump intake, means you're close to trouble.

If you don't have a well sounder, a local well contractor will run this check for $75-$150 in most regions. Ask them to note the depth to water, the depth to the pump, and the total well depth on the invoice. Keep that paperwork with your other property records, the same way you'd track drainage jobs before rainy season so you have a baseline to compare against next time.

Should you deepen the well or drill a new one?

You should deepen the existing well if the casing and pump are in good shape and the aquifer just needs a lower draw point. You should drill a new well if the casing is old, cracked, or undersized, or if the aquifer feeder itself has dropped below what deepening can reasonably reach.

| Option | Typical Cost | Timeline | Best For | |---|---|---|---| | Deepen existing well | $2,000-$5,000 | 1-2 days | Sound casing, aquifer just lower than before | | Drill new well | $8,000-$15,000+ | 1-2 weeks | Old/damaged casing, dry aquifer, contamination |

A driller can tell you which situation you're in after pulling the pump and inspecting the casing. Get two quotes if the estimate is over $5,000. In many counties you'll also need a permit before either job starts, so check with your county health department first.

What should you do while you wait for the well to recover?

You should cut nonessential water use immediately and space out high-draw activities like laundry and irrigation. Running the washing machine, dishwasher, and sprinklers back to back is the fastest way to pull a marginal well dry mid-cycle. Spread those tasks across the day instead, and skip lawn watering during a dry spell entirely.

Check your water heater and any visible plumbing for leaks while you're at it, since a slow drip wastes water you can't afford to lose right now. The same logic that explains water pooling under a water heater applies here: small leaks compound fast when supply is already tight. If you have a holding tank or cistern as backup, now's the time to fill it and keep an eye on the level daily instead of monthly.

Could nearby construction or drought be draining your well?

Yes, both are common culprits and worth ruling out before you spend money on your own well. A new well drilled by a neighbor within a quarter mile, a nearby quarry or construction project pumping groundwater, or a regional drought can all lower your local water table independent of anything wrong on your property. Check with your county extension office or state geological survey for regional water table data before assuming the problem is isolated to your well.

FAQ

How long can a well be dry before it recovers on its own?

Most wells recover within a few days to a few weeks once rain returns or heavy usage nearby stops, but a well that's been fully dry for over a month may indicate a permanent drop in the aquifer rather than a temporary dip.

Does a low well affect water quality, not just quantity?

Yes. As the water level drops toward the pump intake, you're more likely to pull in sediment, and in some cases bacteria or minerals that were previously below the draw point, so a water quality test is worth doing alongside the level check.

How much does it cost to replace a well pump versus the whole well?

A submersible pump replacement typically runs $800-$2,500 depending on depth and horsepower, while a full well replacement runs $8,000-$15,000 or more, so it's worth confirming the pump itself isn't the actual problem before assuming the well is dry.

Can I install a water storage tank instead of fixing the well?

A cistern or storage tank can buy you time by storing water during low-demand hours for use during peak draw, but it doesn't fix a genuinely depleted aquifer and usually costs $1,500-$4,000 installed depending on size.

Is it normal for well output to drop every summer?

A modest seasonal dip is normal in most regions as the water table naturally lowers during dry months, but if the drop is getting worse year over year or lasting longer into fall, that trend line matters more than any single summer's reading.
