🔥 Balboa Vico Power WOW Bath Pump 1074002 — 1.5 HP 115V 13A Whirlpool Bath Pump with Air Switch & NEMA Cord

Maximum power WOW platform — built for large whirlpool tubs with 8+ jets demanding serious hydrotherapy performance

📋 Product Overview

The Balboa Vico Power WOW 1074002 is the 1.5 HP flagship of the WOW bath pump family — the most powerful single-speed whirlpool bath pump in the Vico-Ultrajet lineup, designed for large jetted bathtubs with 8 or more jets that demand maximum water volume and pressure. Drawing 13A at 115V, this pump sends a large volume of water through more bath jets than any other WOW model, making it the choice for premium, high-jet-count whirlpool installations.

Balboa describes the Power WOW as needing “more might to send a larger volume of water through more bath jets” — and the 1074002 delivers exactly that. Despite the significantly higher motor power, the Power WOW maintains the same ultra-compact design that doesn’t demand additional space or cooling beyond the standard WOW footprint. The pump features a 3-1/2″ wet end, self-draining volute, 3/8″ barb auxiliary ports on both suction and discharge for optional air injection, and the same UL/CSA-approved construction that gives the WOW family its less than 0.1% failure rate.

This pump comes plug-in ready with a NEMA power cord (3-prong grounded plug) and a built-in air switch. With 1-1/2″ Male Buttress Thread (MBT) connections, the 1074002 directly replaces legacy 13A bath pumps including the discontinued 1034002, G&G Industries 97611 series, and multiple OEM part numbers.

⚠️ NOTE: This is a whirlpool bath pump for jetted bathtubs. It is NOT a hot tub/spa jet pump or circulation pump. Bath pumps are designed for intermittent use during bathing, not 24-hour continuous operation.

🛠️ Installation Guide

Before You Begin

1. Verify electrical capacity — This pump requires a dedicated 20A GFCI-protected circuit. Have a licensed electrician verify before purchasing
2. Disconnect power — Unplug the old bath pump before any work
3. Access the pump — Remove the access panel beneath the whirlpool tub
4. Note the existing layout — Take photos before disconnecting anything
5. Have towels ready — Residual water may drain when disconnecting unions

Installation Steps

1. Disconnect the old pump — Unplug the power cord, disconnect union fittings, and remove the pump
2. Position the new Power WOW pump — Place in the mounting location beneath the tub
3. Connect the plumbing — Thread the union fittings onto the 1-1/2″ MBT ports. Suction connects to the bottom port; discharge connects to the center/front port
4. Connect auxiliary ports — If using air injection, connect 3/8″ air tubing to the barb ports. Cap any unused auxiliary ports
5. Hand-tighten unions — Then snug with a wrench. Do not overtighten
6. Connect the air hose — Run the pneumatic air hose from the tub deck button to the air switch port on the pump
7. Fill the tub — Ensure water covers all jets and the pump is primed before powering on
8. Plug in the pump — Connect the NEMA cord to a 20A GFCI-protected 115V outlet on a dedicated circuit
9. Test operation — Press the air button to toggle the pump on. Verify water flows through all jets

Important Installation Notes

❓ Frequently Asked Questions

Q: What’s the difference between the 1074002 and the 1034002? A: The 1034002 is the discontinued/obsolete predecessor. The 1074002 is the current replacement. They are the same pump. If you’re replacing a 1034002, order the 1074002.

Q: Do I need a 20A circuit for this pump? A: Yes. At 13A, this pump exceeds the safe continuous load for a 15A circuit (which is rated for only 12A continuous per NEC 80% rule). A dedicated 20A GFCI-protected circuit is required. Have a licensed electrician verify your circuit before installation.

Q: What’s the difference between the 1074002 and 1074019? A: The 1074002 includes a built-in air switch. The 1074019 is the same pump without the air switch (NEMA cord only). Choose the 1074002 if your tub uses a pneumatic air button; choose the 1074019 if it uses an external electronic control.

Q: Is the amperage 13A or 13.5A? A: Most sources, including Spa Parts Plus and Amazon, list 13A or 13.0A. Some distributors list 13.5A. This variation may reflect different measurement methods or motor production revisions. Size your circuit for 13.5A to ensure adequate capacity.

Q: Can I upgrade from a smaller WOW model to this one? A: The physical dimensions are similar to other WOW models, so it may fit the same space. However, the 1.5 HP requires a 20A dedicated circuit — if your current circuit is only 15A, you’ll need an electrical upgrade before installing this pump. Also verify your tub’s plumbing and jets are designed for the higher flow.

Q: What size plumbing connections does this pump have? A: Both suction and discharge are 1-1/2″ Male Buttress Thread (MBT), with an outside diameter of approximately 2-7/16″. Union fittings are sold separately.

Q: Does the air switch button come with the pump? A: The pump includes the built-in air switch mechanism. The deck-mounted air button and air hose are sold separately.

Q: Does this pump drain itself? A: Yes. The self-draining volute empties water from the pump body after each use. There is no drain plug.

Remember that this is a general guideline, and the specific steps may vary based on your hot tub's design. If you're unsure or uncomfortable with any aspect of this process, please do get in touch, happy to help.

How do I know what size hot tub pump I have?

Determining the size of your hot tub pump is an important step when it comes to maintenance or replacement. To find out the size of your hot tub pump, follow these steps:

1. Check the Manual: The easiest way to determine the size of your hot tub pump is to consult the owner's manual or user documentation that came with your hot tub. The manual typically contains detailed information about the specifications and components of your hot tub, including the pump.

2. Look at the Pump Housing: If you don't have access to the manual or it doesn't provide the information you need, inspect the pump itself. Most hot tub pumps have a label or plate on the pump housing that displays essential details, including the pump's model number, manufacturer, and specifications. You can then send that to me or Google it.

3. Measure the Pump: If the label is missing or damaged, you can measure the pump's dimensions. Measure the diameter of the pump's wet end (the part where the water flows) and the length of the wet end. These measurements can help identify the size and capacity of the pump.

4. Consult the Manufacturer: If you can't find the information on the pump or in the manual, contact the hot tub manufacturer or a reputable dealer. Provide them with your hot tub's model and serial number, and they should be able to identify the correct pump size for your specific hot tub.

5. Online Research: You can also search online using the pump's model number or hot tub's make and model. Many manufacturers provide detailed information about their products on their websites, and you may find specifications for your pump model.

Once you have determined the size and specifications of your hot tub pump, you can proceed with maintenance, repairs, or replacement if necessary. Keep in mind that replacing a hot tub pump with the same size and capacity as the original is crucial to ensure proper water circulation and filtration in your hot tub. If you're unsure about any aspect of this process, get in touch, always happy to help.
