Red Lion RL12G15-3W2V — 1.5 HP 12 GPM Deep Well 4" Submersible Pump (230V, 3-Wire)
The Red Lion RL12G15-3W2V is a high-head 4" submersible deep-well pump designed for residential and light commercial water systems requiring long vertical lift. With a powerful 1.5 HP motor, stainless steel construction, built-in check valve, and efficient thermoplastic impellers, it delivers a steady 12 GPM output from wells as deep as 500 feet.
Key Features & Benefits
- 1.5 HP high-head performance for deep wells and tall vertical runs.
- 12 GPM flow rate engineered for consistent whole-home pressure.
- 3-wire, 230V motor for reliable starting torque and serviceability. Control box included with all 3-wire pumps (1/2–1 hp)
- Stainless steel pump housing resists corrosion and extends service life.
- Built-in check valve to prevent backflow and pump cycling wear.
Applications
- Deep wells up to 500 ft
- Residential home water systems
- Farm, livestock, and remote supply systems
- Long-run plumbing and high elevation lift installations

Common Questions
Q: How is this different from the 3/4 HP model?
A: The RL12G15-3W2V delivers the same 12 GPM flow, but at much greater depth, making it ideal for tall elevation or wells up to 500 ft.
Q: Does it need a control box?
A: Yes — as a 3-wire motor, a compatible 230V control box is required.
Q: Is this safe for drinking water?
A: Yes, it is suitable for potable systems when installed per code.
Q: What pipe size does it connect to?
A: Standard 1-1/4" NPT discharge.
The RL12G15-3W2V is the deep-well solution when you need long-drop performance and consistent residential water pressure — even at 500 ft.
