🛁 Waterway Genesis Bath Pump 321NF10-0150 — 1.5 HP 1-Speed 115V with Air Switch & Cord

Ultra-quiet, self-draining bath pump — plug-in ready with built-in air switch for whirlpool tubs

🔄 Product Overview

The Waterway Genesis Generation (Part No. 321NF10-0150) is an energy-efficient 1.5 HP, single-speed bath pump designed, engineered, and manufactured in the USA by Waterway Plastics of Oxnard, California. Purpose-built for whirlpool bath and jetted bathtub installations, the Genesis delivers powerful hydrotherapy at 3,450 RPM through a whisper-quiet wet end with self-draining design — all in a remarkably compact package measuring just 12.82″ long.

What makes the Genesis a standout choice for bath applications is its plug-and-play convenience: the pump ships as a complete package with a 3-foot NEMA power cord (3-prong plug), a factory-installed air switch for bather-activated on/off control, and three anti-vibration pads to minimize noise and vibration transfer to the tub structure. The 1-1/2″ MBT center discharge and bottom suction configuration with a glass-reinforced composite housing, dry-run mechanical seal, and UL/CSA listing makes this pump a reliable, code-compliant choice for residential whirlpool bath installations. Two auxiliary 3/8″ barb ports (one on suction side, one on discharge side) come factory-plugged and can be drilled out if needed for small auxiliary lines.

Ensure your circuit is rated for the full 13.5A draw. Waterway reserves the right to change motor brands or styles without notice — functionality remains the same.

⚠️ IMPORTANT:

All electrical work must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local and state building codes.

This pump is designed for plug-in operation with the included 3-prong NEMA cord. The outlet must be on a dedicated circuit with GFCI (Ground Fault Circuit Interrupter) protection as required by the NEC for whirlpool bath installations.

Do not use an extension cord. The pump must be plugged into a properly grounded, GFCI-protected outlet within reach of the 3-foot cord.

The factory-installed air switch provides bather-activated on/off control — no additional switch is needed in most installations.

❓ Frequently Asked Questions

Q: What horsepower is this pump? A: 1.5 HP, single speed at 3,450 RPM.

Q: Does this pump come with a power cord? A: Yes. The Genesis 321NF10-0150 includes a 3-foot NEMA power cord with a 3-prong plug — ready for plug-in installation into a GFCI-protected outlet.

Q: Does this pump include an air switch? A: Yes. The air switch is factory-installed. Route the air tubing from the pump to the air button mounted on the tub rim for bather-activated on/off control.

Q: What size are the ports? A: Both suction (bottom) and discharge (center) are 1-1/2″ MBT (Male Buttress Thread). The outer thread diameter is approximately 2-7/16″.

Q: Is this a hot tub pump or a bath pump? A: The Waterway Genesis is primarily designed as a whirlpool bath / jetted bathtub pump. It features a self-draining design, built-in air switch, plug-in cord, and 1-1/2″ plumbing — all optimized for residential bath applications. It can be used in some smaller plug-in hot tubs but is not designed for larger spa installations with 2″ plumbing.

Q: What are the auxiliary ports on the face of the pump? A: There are two 3/8″ barb ports — one on the suction side and one on the discharge side. They come factory plugged. If you need them for small auxiliary lines, they can be drilled out on-site.

Q: What voltage does this pump require? A: 115V / 60Hz. It plugs into a standard household outlet. The outlet must have GFCI protection per the NEC.

Q: What seal does this pump use? A: The Genesis uses a dry-run mechanical seal (replacement part number 35-423-1060), designed specifically for the intermittent operation typical of bath pump use.

Q: What is the difference between 321NF10-0150 and 321NF10-1150? A: The -0150 suffix indicates bulk packaging (quantity 18), while -1150 indicates individual packaging (quantity 1). The pump itself is identical.

Q: Does this pump self-drain? A: Yes. The Genesis features a self-draining suction inlet design that allows water to drain from the pump after each use, preventing stagnant water from sitting in the pump housing between uses.

Q: How quiet is this pump? A: The Genesis features an ultra-quiet wet end design and includes 3 anti-vibration pads to minimize noise and vibration transfer to the tub structure. It is specifically engineered for bath installations where noise is a primary concern.

Q: What warranty is included? A: 1-year manufacturer warranty from Waterway Plastics. Contact Parts4Tubs for full warranty terms.

Q: Do I need a GFCI outlet? A: Yes. GFCI (Ground Fault Circuit Interrupter) protection is required by the National Electrical Code (NEC) for all whirlpool bath installations. Plug the pump only into a GFCI-protected outlet on a dedicated circuit.
