Well Pump Producing No Water: Troubleshooting Steps

A well pump that delivers no water at the tap represents one of the most disruptive failures in a private water supply system, affecting an estimated 13 million households that rely on private wells across the United States (U.S. Environmental Protection Agency, Private Drinking Water Wells). The failure may originate in the electrical supply, the pump motor, the pressure system, the well casing, or the aquifer itself — each requiring a distinct diagnostic path. This reference describes the structured troubleshooting framework applied by licensed well pump technicians and water well contractors, and identifies the regulatory and safety boundaries that define when professional intervention is required.

Definition and scope

A "no-water" condition in a well pump system is defined as zero or negligible flow at point-of-use outlets despite the pressure tank and distribution lines being otherwise intact. It is distinct from low-pressure complaints or intermittent flow, though both may share upstream causes.

The scope of this condition encompasses three principal system types found in residential and light-commercial private water supply:

• Submersible pump systems — motor and pump assembly suspended within the well casing, typically 4 to 6 inches in diameter, serving depths from 25 to more than 400 feet.
• Jet pump systems (shallow well) — surface-mounted units drawing from depths no greater than 25 feet via suction lift.
• Jet pump systems (deep well) — surface-mounted units employing a two-pipe ejector assembly for depths between 25 and 110 feet.

The Well Pump Listings directory catalogs licensed contractors organized by system type and service region, providing a reference point for matching fault type to qualified service provider.

National standards governing private water well construction and pump installation are anchored in the National Ground Water Association (NGWA) standard ANSI/NGWA-01, which defines minimum requirements for well casing integrity, pump placement, and well seal specifications (NGWA Standards).

How it works

A functioning well pump system operates through a closed loop of electrical activation, mechanical water lift, pressure regulation, and storage. When any single component in this chain fails, the result can be a complete absence of deliverable water.

The diagnostic sequence used by water well service professionals follows a structured fault-isolation protocol:

1. Confirm electrical supply — Verify that the pump circuit breaker has not tripped. Double-pole breakers serving submersible pumps are typically rated at 20 to 30 amperes. A tripped breaker may indicate an overload, a wiring fault, or a failed motor.
2. Check the pressure switch — The pressure switch, set to cut in at 20, 30, or 40 PSI depending on system design, activates the pump motor. A failed switch, corroded contacts, or a waterlogged pressure tank can prevent activation. Switch-cut-in pressures and tank pre-charge pressures are matched specifications; a mismatch disables system cycling.
3. Evaluate pressure tank condition — A waterlogged tank (bladder failure) mimics pump failure at the tap. Pre-charge pressure should be set to 2 PSI below the cut-in pressure of the switch, per standard industry practice.
4. Inspect control box (submersible systems) — Three-wire submersible pump motors route through a surface-mounted control box containing start and run capacitors. Capacitor failure is one of the most common causes of motor non-start in this configuration.
5. Test well yield and static water level — If electrical and mechanical components check out, reduced or depleted aquifer yield may be the cause. A licensed well driller or pump contractor can perform a drawdown test to assess this.
6. Inspect pump intake and drop pipe — Sediment blockage, a broken drop pipe, or a detached pump wire inside the casing prevents water delivery even when the motor is energized.

Safety during this process is governed by OSHA 29 CFR 1926 Subpart P (excavation and soil safety) where applicable for pitless adapter access, and by NFPA 70 (National Electrical Code) for all electrical work on pump circuits (NFPA 70).

Common scenarios

Four failure scenarios account for the majority of no-water calls in residential well systems:

Tripped breaker / burned fuse — Often the result of a locked rotor condition in an aging motor. Resetting without identifying the root cause risks motor burnout or fire.

Dry well / low water table — Seasonal drawdown, drought conditions, or over-pumping lowers the static water level below the pump intake. This is particularly common in shallow aquifer systems during extended dry periods. Some state programs, such as those administered under state well registration requirements, document historical yield data usable in diagnosis.

Failed pressure switch or pressure tank — Pressure switches rated for residential service have a typical service life of 5 to 10 years. Waterlogged tanks cause rapid pump cycling ("short cycling"), which accelerates motor wear and can precede a no-water event.

Broken or disconnected drop pipe — In submersible systems, the drop pipe (typically Schedule 80 PVC or stainless steel) may fracture at joints due to water hammer, age, or improper installation depth. The pump runs but water cannot reach the surface.

Decision boundaries

Not all no-water troubleshooting falls within the competency boundary of a property owner or general handyman. The directory purpose and scope page outlines how licensed contractor categories are structured in this sector.

Owner/operator scope: Checking breakers, inspecting visible pressure switches, and verifying tank pre-charge pressure fall within standard owner maintenance tasks in most jurisdictions.

Licensed contractor required: Any work involving pulling a submersible pump from a well casing, replacing electrical components inside the pump control box, or conducting a drawdown test requires a licensed water well contractor in jurisdictions that enforce NGWA or state-level licensing standards. As of the most recent NGWA policy survey, 48 states maintain some form of well contractor licensing or certification requirement (NGWA State Licensing Information).

Permit and inspection triggers: Well pump replacement — not merely repair — may trigger a permit requirement under state well construction codes. In states operating under U.S. EPA primacy for drinking water under the Safe Drinking Water Act (42 U.S.C. § 300f et seq.), state well programs define these thresholds. California, Texas, and Florida each maintain distinct permitting frameworks under their respective state environmental or health agencies.

Bacteriological testing is required after any pump replacement that involves disturbing the well seal, per NGWA ANSI/NGWA-01 standards and the EPA's Drinking Water from Household Wells guidance (EPA Household Wells Guidance).
