🔧 Waterway E-Series 1.5 HP SPL Spa Pump (3420610-15) — Dual-Speed 115V 48 Frame Center Discharge Jet Pump with 1-1/2″ Connections
High-Performance Center Discharge Power on 115V — The Strongest E-Series Pump for Hot Tubs, Whirlpool Baths, and Spa Systems Running Standard Household Voltage
♨️ Product Overview
The Waterway E-Series 3420610-15 is a 1.5 HP SPL dual-speed center discharge jet pump manufactured by Waterway Plastics in the United States. This is the highest-horsepower model in the E-Series 115V center discharge lineup, delivering 16.4 amps on high speed (3450 RPM) and 4.4 amps on low speed (1725 RPM) — providing substantially more jet power than the 0.75 HP and 1.0 HP E-Series models while still operating on a standard 115V/60Hz household circuit.
The E-Series center discharge design positions the suction port at the front face (center) and the discharge port at the top of the wet end, distinguishing it from side discharge pumps like the Waterway Executive or Hi-Flo series. This configuration is common in whirlpool baths, smaller to mid-size hot tubs, and entry-level spa systems. The 1-1/2″ MBT (Male Buttress Thread) connections on both intake and discharge (approximately 2-7/16″ across threads) connect to standard 1-1/2″ ID plumbing.
As with all E-Series pumps, this model is the current-production replacement for the older Waterway center discharge pump line. The E-Series is identified by its 6-screw faceplate on the wet end (the older discontinued design had a 4-screw faceplate). The wet end can be rotated to match existing plumbing, and the pump features silicon carbide seals with Viton bellows and a 316 stainless steel seal casing.
This pump includes two 400-4060 pump unions that accept 1-1/2″ PVC pipe. Power cord is NOT included. California Title 20 Compliant. Backed by a 1-year manufacturer warranty from Waterway Plastics.

- Be sure to look at the motor voltage on your existing pump, not the voltage supplied to the spa, to determine the correct pump voltage.
🔄 Compatibility Guide
Discharge Configuration — Center vs Side
This pump has a CENTER DISCHARGE configuration. The intake (suction) faces forward from the center of the wet end, and the discharge exits from the top. This is fundamentally different from SIDE DISCHARGE pumps (Waterway Executive, Hi-Flo, etc.) where both ports exit from the front face. If your existing pump has a side discharge, this pump is NOT a direct replacement.
Port Size — 1-1/2″ Connections
Both intake and discharge use 1-1/2″ MBT connections (approximately 2-7/16″ across the outside of the threads). These connect to 1-1/2″ inner diameter plumbing. If your existing pump has 2″ connections (~3-1/16″ across threads), this pump will NOT fit your plumbing without adapters.

⚠️ Union Compatibility Warning
There is no industry standard for pump unions — different pump brands (Waterway, Aqua-Flo, Balboa, LX) use their own unique thread styles and sizes. The unions included with this pump (400-4060) are designed for Waterway connections. If you are replacing a pump from a different manufacturer, you will most likely need to cut off your old unions and install the new ones included with this pump. If your heater is directly coupled to the pump wet end, the unions may not be compatible — contact Parts4Tubs for assistance.
⚠️ Old Center Discharge vs New E-Series
The Waterway E-Series replaced the older Waterway center discharge pump. Parts between the two designs are NOT interchangeable. The easiest way to identify which version you have is the faceplate screw count: the old center discharge pump has a 4-screw faceplate, while the new E-Series has a 6-screw faceplate. If you have the old 4-screw version and need wet end parts, you will need to replace the entire wet end with the new E-Series center discharge wet end (310-1140 for 1.5 HP).
⚠️ E-Series vs Executive — Choosing the Right Pump
The Waterway E-Series and Executive series are different pump lines, even when both are 1.5 HP and 115V. The E-Series uses 1-1/2″ connections with center discharge, while the Executive uses 2″ connections (or 2-1/2″ × 2″) with side discharge. They are NOT interchangeable. If your existing pump has 2″ ports (~3-1/16″ across threads), you need the Executive series (e.g., 3420610-1A), not this E-Series pump.
🛠️ Installation Requirements
Mounting
| Requirement | Specification |
|---|---|
| Mounting Position | Horizontal |
| Base Type | Includes mounting feet |
| Motor Ventilation | Ensure adequate airflow around motor |
| Service Access | Allow clearance for maintenance and wet end rotation |
Plumbing Connections
| Connection | Size | Thread OD | Type |
|---|---|---|---|
| Suction (Intake) | 1-1/2″ | ~2-7/16″ | MBT — Center face |
| Discharge (Output) | 1-1/2″ | ~2-7/16″ | MBT — Center top (rotatable) |
Wet End Rotation
The pump head can be rotated by loosening the motor thru-bolts and turning the pump head. This allows the discharge to be pointed to the 3 o’clock, 9 o’clock, or other positions to match your existing plumbing. Retighten the bolts evenly after rotation.
Installation Notes
⚠️ When matching a replacement pump, verify the motor voltage on your existing pump — not the voltage supplied to the spa. Some spas have 230V supply but use 115V pumps.
⚠️ Pump unions are NOT universal. Use the included 400-4060 unions. You may need to cut off old unions and install the new Waterway unions.
⚠️ Pump must be installed below water level (flooded suction) for proper operation.
⚠️ Never run the pump dry — this damages the mechanical seal.
⚠️ Ensure proper grounding and bonding per NEC requirements.
⚠️ GFCI protection is required by code for all hot tub and spa installations.
⚠️ Power cord NOT included. Reuse your existing cord. Label the wires before disconnecting from the old pump.

❓ Frequently Asked Questions
Q: What is the difference between the 3420610-15 (E-Series 1.5HP) and the 3420310-15 (E-Series 0.75HP)? A: Both are Waterway E-Series center discharge pumps with 1-1/2″ connections on 115V. The key difference is power: the 1.5 HP SPL draws 16.4A on high speed vs 8.8A for the 0.75 HP. The 1.5 HP delivers significantly more jet pressure and flow. Both use the same 48-frame platform, but they have different wet ends (310-1140 for 1.5HP, 310-1120 for 0.75HP) and impellers (310-8030 for 1.5HP, 310-8010 for 0.75HP). Before upgrading, verify your circuit can handle the higher 16.4A draw.
Q: What is “1.5 SPL” horsepower? A: SPL stands for Service/Peak Load — a horsepower rating that represents the maximum output the motor can deliver. This rating method often produces a higher number than “continuous duty” HP ratings used by other manufacturers. Always match pumps by amperage (16.4A high / 4.4A low at 115V) rather than horsepower.
Q: Is this the same as the Waterway Executive 1.5HP pump? A: No. The E-Series and Executive are completely different pump lines. The E-Series 3420610-15 has 1-1/2″ ports (~2-7/16″ across threads) with center discharge. The Executive 3420610-1A has 2″ ports (~3-1/16″ across threads) with side discharge. They are NOT interchangeable — check your port size and discharge type before ordering.
Q: What voltage does this pump use? A: This pump operates on 115V / 60Hz. It requires a standard 115V circuit rated for at least 16.4 amps continuous. If your spa requires a 230V pump, this is NOT the correct model.
Q: Can I replace my 0.75HP E-Series with this 1.5HP model? A: Physically yes — they share the same 48-frame, 1-1/2″ connection size, and center discharge configuration. However, the 1.5 HP draws 16.4A on high speed versus 8.8A for the 0.75 HP. Your circuit breaker and wiring must be able to handle the higher current draw. Consult a licensed electrician before upgrading.
Q: Does this pump replace the old Waterway center discharge pump? A: Yes. The E-Series is the current-production replacement for the older Waterway center discharge pump line. However, wet end parts between the old (4-screw faceplate) and new E-Series (6-screw faceplate) are NOT interchangeable. If you have the old 4-screw pump and need parts, you must replace the entire wet end with the E-Series version (310-1140 for 1.5HP).
Q: What size are the ports? A: Both intake and discharge are 1-1/2″ MBT connections. The outside of the threads measures approximately 2-7/16″. These connect to 1-1/2″ inner diameter plumbing.
Q: Can I use my old unions with this pump? A: Possibly not. Pump unions are NOT standardized across brands. This pump includes two 400-4060 unions designed for Waterway connections. If replacing a non-Waterway pump, you will likely need to cut off the old unions and install the included Waterway unions.
Q: Does this pump come with a power cord? A: No. Reuse the power cord from your existing pump. Label the wires before disconnecting from the old pump. The wiring diagram is on the motor nameplate.
Q: What warranty is included? A: This pump carries a 1-year manufacturer warranty from Waterway Plastics from date of purchase when installed by a qualified installer. Proof of purchase is required for warranty coverage. Contact Parts4Tubs for warranty claim details.
Q: Do I need a GFCI? A: Yes, GFCI (Ground Fault Circuit Interrupter) protection is required by the National Electrical Code (NEC) for all hot tub and spa installations.
