🔩 Balboa Ultimax Power WOW Spa Pump 7154213-S — 3.0 HP 1-Speed 230V Compact Jet Pump

Ultra-compact, ultra-quiet — the industry-leading Power WOW delivers big performance from the smallest footprint in spa pumping

📋 Product Overview

The Balboa Ultimax Power WOW (Part No. 7154213-S) is a 3.0 HP rated / 2.0 HP continuous, single-speed, 230V/60Hz compact jet pump from the acclaimed Vico Ultimax product line by Balboa Water Group. The “big brother” of the original WOW bath pump, the Power WOW is engineered to deliver more power without requiring additional space or cooling — making it the industry leader when high water volume needs to move through more jets in a compact equipment bay.

This pump features the unique Ultimax wet end paired with a compact 15-frame motor — dramatically smaller than the standard 48-frame and 56-frame spa pumps. Despite its compact size, it draws only approximately 6.0–6.5A at 230V and produces powerful single-speed jet output at 3,450 RPM. The Power WOW is UL and CSA approved and designed to meet the most strict municipal noise requirements with ultra-quiet operation.

The self-draining volute prevents water retention for hygienic storage and freeze protection, while the multi-directional discharge can be rotated to 4 positions (12, 3, 6, and 9 o’clock) by loosening the four throughbolts. The 2″ MBT center suction and 2″ MBT side discharge connect to standard 2″ spa plumbing (~3.1″ thread outer diameter). All seals are carbon ceramic with Viton® elastomers for long-lasting performance in harsh spa chemical environments.

The 7154213-S replaces numerous discontinued Vico/Balboa Ultimax models including 1056029, 1056037, 1016176, 1056176, and many more. It is used as OEM equipment in Artesian Spas and other major brands. With approximate dimensions of just 13.5″ L × 8.5″ H × 7.35″ W, it fits equipment bays where even a 48-frame pump would be too large.

**PLEASE READ THIS IS IMPORTANT**

When selecting a Balboa Ultimax or Vico Ultimax pump, you must pay careful attention to the wet end. The is the black part on the end of the pump which connects to the plumbing and has the impellor inside.

Balboa have made this pump under various OEM agreements, for the likes of CalSpa amongst others who have then included it in their hot tubs.

Whereas normally with a pump, you can select the voltage, horsepower and frame size, it is a little more difficult with this brand. There are different types of wet end for this model and the discharge (the part that connects to the pipework that flows to your jets) can be in a different position. Normally, you would choose from either side discharge, or center discharge but "helpfully" (not at all!) Balboa has a different offset for the side discharge on this model. THIS IS NOT STANDARD.

If you get this wrong, the part will not fit.

Please take a look at the two different examples below. Both of these are for a 2HP pump but you can see they look totally different. You will also notice that the position of the discharge is roughly 1" different. The one on the left is offset around 2.5" and the one on the right is offset around 1.5".

If you are looking to replace a pump and you need a non-standard wet end, you will need to buy a new pump AND the wet end that you need. Please note, in some cases you will just need to change the Volute (impeller cover)

The standard model comes already fitted to the pump whereas the non-standard model will need to be purchased separately, and you will need to change this over. 

If you are comfortable enough to switch out a pump, changing a wet end over should not be a problem for you.

If you are not sure, please do get in touch.

How do I Replace a Hot Tub Pump?

Here's a general step-by-step guide on how to replace a hot tub pump. Keep in mind that the specific steps may vary depending on your hot tub's make and model, so it's essential to consult your hot tub's manual for model-specific instructions. If you're not comfortable with this procedure, it's a good idea to seek professional assistance.

Materials You'll Need:

• Replacement pump
• Pipe wrench
• Adjustable wrench
• Screwdriver
• Pipe sealant (thread tape or plumber's putty)
• PVC primer and cement (if you have PVC plumbing)
• Teflon tape (for threaded connections)

Procedure:

1. Turn Off the Power: Before you begin, ensure the hot tub's power supply is turned off at the circuit breaker or disconnect switch. Safety should always be a priority when working with electrical components.

2. Drain the Hot Tub: If your hot tub is not already empty, you'll need to drain it. Follow your hot tub's manual or manufacturer's instructions for proper draining. (You might not need to do this if you can lock the pump off with the gate valves)

3. Locate the Pump: Identify the location of the existing pump in your hot tub. It's usually located near the equipment area or in a designated pump compartment.

4. Disconnect the Electrical Wiring: Carefully disconnect the electrical wiring from the old pump. This typically involves removing the electrical conduit cover, unscrewing wire nuts, and disconnecting the wires from the terminals. Be sure to note the wire connections or take a picture for reference when connecting the new pump.

5. Disconnect the Plumbing: Depending on your hot tub's plumbing setup, you'll need to disconnect the plumbing connections to the pump. Use a pipe wrench or adjustable wrench to loosen and remove the fittings. Be prepared for some water spillage when disconnecting the plumbing.

6. Remove the Old Pump: Once the electrical and plumbing connections are detached, carefully remove the old pump from its mounting position. Some pumps may be secured with mounting brackets or bolts.

7. Prepare the New Pump: If the new pump is not pre-assembled, you may need to attach fittings, unions, or adapters to match your hot tub's plumbing. Ensure that you use the appropriate sealant or Teflon tape on threaded connections to prevent leaks.

8. Mount the New Pump: Position the new pump in the same location as the old one and secure it in place using the mounting brackets or bolts.

9. Reconnect Plumbing: Reconnect the plumbing to the new pump, ensuring that all connections are tight and secure. If your hot tub uses PVC plumbing, use PVC primer and cement to bond the connections properly.

10. Reconnect Electrical Wiring: Reconnect the electrical wiring to the new pump, following the notes or pictures you took earlier. Make sure all wires are properly connected and secure.

11. Turn On the Power: Restore power to the hot tub by switching on the circuit breaker or reconnecting the disconnect switch.

12. Test the Pump: Turn on the hot tub's pump to ensure that it's working correctly. Check for any signs of leaks or irregularities in the plumbing connections.

13. Refill the Hot Tub: Once you've confirmed that the new pump is functioning properly, refill the hot tub with water.

14. Check for Leaks: Inspect the plumbing connections for any leaks. If you find any, turn off the pump, drain the tub again, and reseal the connections as needed.

15. Monitor: Keep an eye on the pump and plumbing for the next few days to ensure everything is functioning correctly and that there are no further issues.

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.
