Buying Guide
Flow Rate and Total Dynamic Head
Flow rate (measured in gallons per minute, or GPM) and total dynamic head (the height the pump can push water) are critical. For a 3/4 HP pump, you typically get 10–12 GPM at moderate depths. The Red Lion RL12G07-2W2V delivers 12 GPM up to 100 feet, with a shut-off of 333 feet. The Tuhorse 3 HP model, though larger, offers 30 GPM at 250 feet, suitable for high-demand systems. Always match the pump’s capabilities to your well’s depth and daily water usage.
2-Wire vs. 3-Wire Motor
Submersible well pumps come in either 2-wire or 3-wire configurations. A 2-wire pump (like the Red Lion RL12G07-2W2V) has the starting capacitor built into the motor, so no external control box is needed—simpler installation. A 3-wire pump (like the Red Lion RL12G15-3W2V) requires a separate control box, which can be easier to service if the capacitor fails. The Tuhorse 3 HP set includes a metal cased control box, making it a 3-wire system.
Build Quality and Materials
Look for corrosion-resistant materials, especially for potable water. The Red Lion pumps feature stainless steel casing and thermoplastic discharge, certified to NSF/ANSI 372 for safe drinking water. The Tuhorse pump uses a brass outlet and meets NEMA industrial standards. Both are durable, but stainless steel offers longevity in harsh well conditions.
Ease of Installation
Installation difficulty varies. The 2-wire Red Lion model is straightforward—no extra control box. The 3-wire models require wiring the control box, which may need a professional. The Tuhorse complete set includes the motor, pump-end, and control box, simplifying the process. Always follow local electrical codes and consider hiring a licensed well contractor.

Both are excellent choices from trusted brands, ensuring years of dependable water service.
Frequently Asked Questions
How deep can a 3/4 HP submersible well pump work?
A 3/4 HP submersible pump can typically lift water from depths up to 300 feet, depending on the flow rate and pipe friction. The Red Lion RL12G07-2W2V has a maximum shut-off head of 333 feet, making it suitable for most residential wells. Always verify your well depth and total dynamic head before purchasing.
What is the difference between 2-wire and 3-wire well pumps?
The main difference is where the starting components are located. A 2-wire pump has the capacitor built into the motor, so no external control box is needed. A 3-wire pump requires a separate control box, which is often mounted above ground. This affects installation cost and ease of troubleshooting. In 2026, many homeowners prefer 2-wire for simplicity, but 3-wire offers easier service access.
