How Do You Choose the Right Well Water Pump?
Choosing a well pump isn't complicated once you understand the basics. The right pump for your home depends on three things: your well depth, your household water demand, and your pressure requirements. Get those three numbers right, and the rest is straightforward. Get them wrong and you're either replacing the pump early or fighting low pressure for years.
All well pump installations in Texas must be performed by a licensed contractor under the Texas Department of Licensing and Regulation (TDLR) — this protects your aquifer and your investment.
Submersible vs. Jet Pump: What's the Difference?
These are the two main types of residential well pumps:
- Submersible pumps — installed deep inside the well casing, submerged in water. Quiet, efficient, and ideal for wells deeper than 25 feet. Most North Texas wells use submersible pumps.
- Shallow well jet pumps — installed above ground and use suction to pull water up. Only work for wells less than 25 feet deep. Less common in this area.
- Deep well jet pumps — can pull from depths up to 100 feet, but less efficient than submersible and harder to service.
For most Fort Worth and Parker County homeowners, a submersible pump is the right call. They're quieter, last longer, and work better in the deep wells common throughout North Texas.
What Size Pump Do You Need?
Pump sizing comes down to two specs: GPM (gallons per minute) and HP (horsepower).
- A typical household of 4 people needs at least 6–8 GPM
- Irrigation or livestock use adds significant demand — plan for 10–15 GPM or more
- Most residential submersible pumps range from ½ HP to 1.5 HP
- Deeper wells (300+ feet) require more HP to overcome the head pressure
Undersizing a pump causes it to run constantly and burn out early. Oversizing wastes energy and can cause pressure surges. Legacy Water Well calculates the right size based on your well depth, static water level, and household demand.
Does Your Pressure Tank Matter?
Absolutely. The pressure tank stores water under pressure so your pump doesn't cycle on and off every time you open a faucet. A properly sized tank protects the pump motor and maintains consistent pressure throughout your home. If your pump is cycling rapidly (short-cycling), it's usually a sign of a failing pressure tank — not the pump itself.
What Are Signs Your Current Pump Needs Replacing?
- Sputtering or air in the water lines
- Sudden drop in water pressure throughout the house
- Pump runs constantly without building pressure
- No water at all
- Pump is more than 10–15 years old and starting to struggle
Don't wait for a complete failure. A struggling pump that runs hot or dry can burn out your motor, which costs more to replace than a planned swap.

Frequently Asked Questions
How long do submersible well pumps last?
A quality submersible pump typically lasts 10–15 years with proper maintenance. Factors like water quality, pump sizing, and how often the pump cycles all affect lifespan.
Can I replace my own well pump?
Technically yes, but it's not recommended. Pulling a submersible pump requires specialized equipment, and an improper installation can damage the pump, the wiring, or the well casing itself. Leave it to a licensed well contractor.
How much does a well pump replacement cost in Texas?
Most residential submersible pump replacements run $1,200–$2,500 depending on depth and pump size. Legacy Water Well provides upfront quotes before any work begins. Call for a free estimate.
