| Feature | Submersible | Jet Pump |
|---|---|---|
| Location | Inside the well, submerged in water | Above ground, in pump house or basement |
| Depth range | Any depth — most common for 25–400 ft wells | Shallow jet: up to 25 ft. Deep jet: up to 80 ft |
| Efficiency | More efficient — pushes water up | Less efficient — pulls water up against gravity |
| Noise | Very quiet — underground | Audible — in pump house or basement |
| Lifespan | 10–15 years with proper maintenance | 10–15 years, easier to service |
| Repair access | Requires pulling the pump from the well | Accessible without entering the well |
| Freeze risk | None — below frost line | Pump house must be heated to prevent freezing |

Frequently Asked Questions
Which type of well pump is better for Maryland?
For most Maryland homes with wells deeper than 25 feet — which is the majority of Calvert and Anne Arundel County wells — a submersible pump is the better choice. It is more efficient, quieter, and not vulnerable to freezing. Jet pumps are still found in older homes and shallow wells, but most new installations use submersible pumps.
How do I know what type of pump I have?
If you have a pump house or a pump visible in your basement or utility room, you have a jet pump. If you only see a pressure tank and electrical connections at the wellhead with no visible pump, you have a submersible pump (the pump is inside the well). You can also check the well tag or call a plumber to identify the system.
How much does it cost to replace a submersible pump in Maryland?
Submersible pump replacement in Maryland typically costs contact us for a free estimate depending on the pump depth, horsepower, and brand. This includes pulling the old pump, installing the new pump and drop pipe, and testing the system. Deeper wells cost more due to the additional labor and materials for the drop pipe and wiring.
Can I convert from a jet pump to a submersible pump?
Yes — converting from a jet pump to a submersible pump is a common upgrade, especially when a jet pump fails and the homeowner wants a more efficient, quieter system. The conversion requires installing a new pump inside the well, running new wiring and drop pipe, and potentially upgrading the pressure tank. Deep Dive Plumbing Maryland handles these conversions regularly.
