Why a private-well home has no water
No water
A failed pump, tripped breaker, bad switch, or the well itself underproducing.
Short cycling
Usually a waterlogged pressure tank that’s lost its air cushion.
Low or fluctuating pressure
A tank not holding air, a misadjusted switch, or sediment restricting flow.
Pump runs continuously
Struggling to keep up with demand or working through a hidden leak. See leak detection and repair.
Pump, tank or switch?
Submersible pump
Inspecting or servicing usually means pulling it — specialized well-contractor work.
Jet pump
Mounted above ground, generally more accessible for inspection and component work.
Pressure tank
Testing and replacement sit squarely within general plumbing work — often the fastest part to evaluate.
Signs of a waterlogged pressure tank
Common signs include the pump cycling on and off rapidly with only light use, a noticeable pressure drop right when a fixture opens, a tank that feels heavy or sounds full when tapped, and higher electrical use from a pump that keeps restarting. None of these alone confirm a waterlogged tank with certainty, since a bad pressure switch can mimic similar behavior — a plumber checks tank pressure directly rather than relying on symptoms alone.
Short cycling & low pressure
These often share the same root cause. When a tank loses its air charge, the pump restarts almost continuously to maintain pressure, and each restart briefly interrupts flow at the fixtures. A pressure switch that’s set incorrectly, worn, or wired loosely can produce a similar pattern with a healthy tank, and sediment or a partially closed valve can add fluctuation on top of either problem. Sorting out which factor is driving the symptom, rather than replacing parts by guesswork, is the point of an on-site inspection.
Testing the plumbing side of the well system
Confirm symptoms & system
When it started, constant or intermittent, and whether anything changed recently, like a power outage.
Inspect & test on site
The tank’s air charge, switch settings, wiring at the house side, and pressure at representative fixtures — not the well casing itself.
Explain findings & boundary
What’s repairable on the plumbing side, and clearly stated if a well contractor is needed.
Pump replacement & access considerations
Whether a pump can be replaced, and how, depends heavily on type and installation. A jet pump mounted above ground is generally more accessible than a submersible pump housed inside the well casing, where retrieval requires specialized rigging and well-contractor expertise. Older wells, unusual casing depths, and limited equipment access can all change what a straightforward-sounding swap actually involves — an on-site inspection is the only way to confirm the pump type and realistic scope before any cost estimate is discussed.
When to call a well driller
If the well may be running low or dry, the casing or wellhead needs inspection, a submersible pump needs pulling, or new construction is being considered, a well driller is the right resource — not a plumber. NY DOH recommends private well owners test their own water periodically; see water softener and filtration if results point to treatment needs.
Water quality after well work
Private well water quality is a separate question from pump or tank function, and one doesn’t confirm the other. The NY State Department of Health notes private well owners are responsible for their own water quality and should test periodically for bacteria and other contaminants, since public suppliers test municipal supplies but private wells aren’t covered by the same requirements. Air, cloudiness, or a taste change after repairs can relate to disturbed sediment, but a qualified testing laboratory should guide any treatment decision. See water softener and filtration if results point to conditioning needs.
Well pump & pressure tank FAQs
Why does my well pump turn on every few seconds?
Short cycling — usually a pressure tank that’s lost its air charge, or a worn pressure switch.
How can I tell if the pressure tank failed?
Rapid cycling with light use, a waterlogged feel, and a pressure drop right when a fixture opens.
Does no water mean the well is dry?
Not necessarily — could be the pump, breaker, switch, or wiring rather than well yield.
Can a plumber replace a well pump?
Depends on the type — jet pumps are within plumbing scope; submersible pumps typically need a well contractor.
Should the water be tested after repairs?
Water quality and mechanical function are separate — NY DOH recommends periodic testing for private wells.
Why is air coming from the faucets?
A low well level, a pump drawing air, disturbed sediment, or a tank problem — an inspection confirms the source.
