A jet pump is an above-ground well pump that uses suction and a venturi nozzle to pull water up from shallow wells. Unlike submersible pumps that sit inside the well, a jet pump mounts in your pump house, garage, or wellhead enclosure — making it accessible for maintenance without pulling anything out of the well.

Jet pumps come in two configurations:

• Shallow well jet pumps — Single-line systems that work on wells up to about 25 feet deep. These are simple, affordable, and easy to service.
• Deep well jet pumps — Two-line (or convertible) systems that use an ejector assembly down in the well to boost suction. These can reach wells up to about 70 feet, though efficiency drops significantly past 50 feet.

In North Texas, jet pumps are relatively uncommon because most wells here tap the Trinity Aquifer at 150–600 feet — well beyond jet pump range. However, we still service plenty of jet pumps on older shallow wells, stock tanks, and properties drawing from the Paluxy formation or alluvial aquifers near creek beds.

If your well is deeper than 50 feet, the answer is almost always yes. Here is why we recommend the upgrade for most North Texas well owners still running jet pumps:

• Efficiency — Submersible pumps push water up instead of pulling it, which uses significantly less energy. Most homeowners see a noticeable drop in their electric bill after converting.
• Pressure and flow — Jet pumps lose efficiency with depth. A jet pump on a 60-foot well might produce 6–8 GPM. A properly sized submersible on the same well can produce 10–15 GPM.
• Reliability — Jet pumps have more above-ground components that can fail: the impeller, mechanical seal, ejector assembly, foot valve, and two lines running down the well. A submersible has fewer failure points.
• Noise — Jet pumps are loud. If yours is in the garage or near the house, you hear it every time the pressure switch kicks on. Submersibles are silent — they are 200 feet underground.
• Freeze protection — Above-ground jet pumps are vulnerable to North Texas cold snaps. A submersible is naturally insulated by ground temperature.

The conversion typically costs $2,500–$4,000 depending on well depth, but pays for itself in reliability and lower operating costs within a few years.

If upgrading is not in the budget right now, we are happy to keep your jet pump running. Common jet pump repairs we handle include:

• Impeller and seal replacement — The most common wear item. Symptoms include reduced pressure and water leaking from the pump housing.
• Foot valve replacement — When the foot valve at the bottom of the well fails, the pump loses prime overnight. You wake up to no water and have to reprime the system.
• Ejector assembly service — On deep-well jet configurations, the nozzle and venturi can clog with scale or sediment, killing performance.
• Pressure switch and control issues — Same electrical components as submersible systems. We diagnose and replace pressure switches, relays, and capacitors.
• Priming problems — If your jet pump keeps losing prime, the issue is usually a foot valve failure, a crack in the suction line, or a bad mechanical seal. We will find it.
