Submersible vs. Jet Pumps: Which Does Your Saratoga County Well Have?
Most homeowners never think about which type of pump their well uses until something goes wrong and it suddenly matters — the two main types, submersible and jet pumps, work differently, fail differently, and get diagnosed differently. Knowing which one your system has before you request service helps you describe the problem accurately and understand what's actually involved in addressing it.
The Basic Difference
A submersible pump does exactly what its name suggests: it sits down inside the well casing, submerged in the water itself, and pushes water up to the house from below. A jet pump, by contrast, stays above ground — usually in a basement, utility room, or well house — and uses suction to pull water up from the well rather than pushing it from below. That single difference in where the pump physically sits shapes almost everything else about how each type is installed, maintained, and repaired. Our submersible and jet pump page covers what each type involves for service in more detail.
How to Tell Which One You Have
The most reliable way to tell is to look at your setup. If you have a wellhead sticking up out of the ground (or capped just below grade) with no visible pump anywhere above ground near it, and the only components in your basement or utility area are a pressure tank and a switch, you almost certainly have a submersible pump — the pump itself is down in the well, out of sight. If instead you can see a compact pump unit, usually with two pipes running to it, mounted above ground near the pressure tank, that's a jet pump. Homes with wells drilled or upgraded more recently are more likely to have submersible pumps; older setups are more likely to still have a jet pump, though either can be found in a home of nearly any age depending on what's been done to the system over the years. If you're not sure, our well pump repair page covers this as one of the first things worth confirming before requesting service.
Why Most Newer Saratoga County Wells Use Submersible Pumps
Submersible pumps have become the standard choice for new wells and replacements for a few practical reasons: they're quieter, since the motor is down in the well rather than in living space; they don't rely on suction, which limits how deep a jet pump can effectively lift water from; and being submerged in water actually helps cool the motor, which can support a longer working life under normal conditions. Jet pumps still show up, particularly in older homes and on shallower wells where suction lift isn't a limiting factor, but submersible pumps have largely become the default for new installations and for replacements on deeper wells.
Can a Jet Pump Be Converted to Submersible?
In many cases, yes — but it's not a simple swap. Converting from a jet pump to a submersible setup generally means running new wiring down into the well, installing a new drop pipe, and reworking the connection at the wellhead, in addition to the pump itself. Whether it makes sense depends on the well's construction, depth, and condition, and on whether the existing jet pump has actually failed or is simply being considered for an upgrade. This is a bigger scope of work than a straightforward like-for-like replacement — see well pump replacement for how that decision typically gets evaluated.
How Deep Can a Submersible Pump Go?
Submersible pumps are built to operate at significant depths — well beyond what a jet pump's suction lift could reach — which is part of why they've become the standard choice as wells get deeper. Actual depth varies well by well across Saratoga County, since the county's geology ranges from glacial till and sand-plain areas to bedrock in other parts of the county, and depth is one of the main things that differs from one well to the next even within the same town. See Well Depth and Geology Across Saratoga County for how local geology shapes typical well depth and what that means for pump selection.
Why This Matters for Repair and Replacement
Because a submersible pump has to be physically pulled up out of the casing to be inspected, repaired, or replaced, that job involves different equipment and access considerations than working on a jet pump, which is already sitting above ground and reachable without pulling anything out of the well. Neither type is inherently more failure-prone than the other, but the process for addressing a failure looks different enough that it's worth knowing which one you have going into a service request. Our well pump repair page covers how each type factors into diagnosing a problem.
Getting the Right Service for Your Setup
If you're not sure which type of pump your well has, that's a completely normal thing not to know — describing what you can see (a wellhead with nothing visible above ground, versus a pump unit you can point to) is usually enough to work out which type you're dealing with before service is scheduled.
