⚡ Balboa Vico Power WOW Bath Pump 1051057 — 1.0 HP 115V 9.0A Whirlpool Bath Pump with Air Switch & NEMA Cord

High-performance Power WOW delivering 86 GPM for larger jetted whirlpool tubs — used by Kohler and American Standard

♨️ Product Overview

The Balboa Vico Power WOW 1051057 is a 1.0 HP single-speed whirlpool bath pump from the Vico-Ultrajet Power WOW range by Balboa Water Group — the high-performance tier of the WOW platform, delivering 86 GPM at 9.0 amps for whirlpool bathtubs with 6 to 8 standard jets that need serious hydrotherapy pressure. This pump is used as OEM equipment by Kohler and American Standard in their premium jetted bath lines.

The Power WOW steps up from the standard WOW with a larger 3.4-inch diameter impeller (5 vanes) while maintaining the same ultra-compact footprint — 13.5″ × 4.85″ × 7.2″. Balboa rates the entire WOW family at a less than 0.1% failure rate, making it the most reliable bath pump platform on the market. The self-draining volute empties the pump body after each use for hygienic operation, and both suction and discharge include 3/8″ barb auxiliary ports for optional air injection connections.

This pump comes plug-in ready with a NEMA power cord (3-prong grounded plug) and a built-in air switch. The air switch activates the pump via a pneumatic button mounted on the tub deck — button and air hose (part 63000) are purchased separately. With 1-1/2″ Male Buttress Thread (MBT) connections on both suction and discharge, the 1051057 is a direct replacement for a wide range of 9.0A whirlpool bath pumps including G&G Industries 97411 series, Hydro Air LD7A, and Ultima 2 models.

⚠️ 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.

🎛️ Air Switch Operation

The Power WOW 1051057 has a built-in pneumatic air switch:

What’s included: The internal air switch mechanism — built into the pump body.

What you need separately: A pneumatic air button (mounted on the tub deck), air hose (part 63000), and union fittings.

How it works: Pressing the air button on the tub deck sends a pulse of air through the hose to the pump’s internal switch, toggling the motor on or off. The pneumatic design keeps all electrical components away from the wet area.

Electronic Switch Option: An electronic switch timer option provides a 30-minute auto-shutoff for enhanced safety.

ℹ️ NOTE: If the motor doesn’t start when plugged in, the air switch may be in the “off” position. Press the air button to toggle it on.

Choose based on your existing pump’s amperage rating.

Q: What’s the difference between the WOW and the Power WOW? A: The Power WOW is the higher-performance tier of the WOW platform. It uses a larger motor and 3.4-inch impeller for more power, while maintaining the same compact footprint, self-draining volute, and ultra-quiet operation as the standard WOW.

Q: What is the old Vico part number for this pump? A: The original Vico part number is 1011057. The current Balboa part number is 1051057. They are the same pump.

Q: Does this pump come with everything I need? A: The pump includes the motor, wet end, built-in air switch, and NEMA power cord. You will need to purchase separately: union fittings (400-4060, 400-4200, or 92065), the air button for the tub deck, and air hose (part 63000) connecting the button to the pump.

Q: My pump has a 3/8″ barb port. What is that for? A: Both suction and discharge have a 3/8″ barb auxiliary port for optional air injection. These ports mix air into the water flow for enhanced jet action. If you’re not using air injection, cap these ports to prevent air leaks.

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.
