A: This is a 1.5 HP dual-speed spa pump. Some sources may reference this as 1.5 OHP (Operational Horsepower) / 2.0 THP (Total Horsepower), which are two different measurement standards for the same motor. Q: Will this fit my hot tub? A: This pump has a 48Y frame with 1-1/2″ MBT connections on both suction (center) and discharge (side). Check your existing pump’s frame size, plumbing size, and connection type for compatibility. The union collar measures approximately 2.5″ (64mm) tip to tip for the 1-1/2″ FBT union size. Q: What voltage does this pump require? A: 115V / 60Hz. This is a standard US household voltage. All electrical installation must be performed by a licensed electrician. A GFCI-protected dedicated circuit is required. Q: Does this pump run on 115V or 230V? A: This specific model (02115000-1010) is 115V only. If you need a 230V version, the corresponding model is 02115005-1010. Using the wrong voltage will damage the motor. Q: Is this a single or dual speed pump? A: This is a 2-speed pump. High speed (14.4A) powers the jets for hydrotherapy. Low speed (5.5A) runs filtration and heating cycles efficiently. Q: What size are the ports? A: Both suction (center) and discharge (side) ports are 1-1/2″ MBT. The physical outer diameter of the connections is 2-7/16″. Q: Does this pump come with a cord? A: No. This pump is designed for hardwire installation to your spa control system. A pump cord (AMP plug) must be purchased separately if required by your spa pack. A compatible 2-speed AMP cord is available from Parts4Tubs (Part# 21087). Q: Can I rotate the discharge direction? A: Yes. The wet end (volute) can be rotated by loosening the four thru-bolts at the back of the motor. This allows you to position the side discharge in the orientation that best suits your plumbing layout. Q: What warranty is included? A: This pump includes a manufacturer’s warranty from Gecko Alliance. Contact Parts4Tubs for full warranty terms and coverage details. Q: How do I know if my pump needs replacing? A: Signs include unusual noise (grinding or screeching), leaking seals, reduced flow, the motor tripping the circuit breaker, or the motor overheating and cycling on/off. Q: Do I need a GFCI breaker? A: Yes, GFCI (Ground Fault Circuit Interrupter) protection is required by the National Electrical Code (NEC) for all hot tub and spa installations in the United States. Q: What seal does this pump use? A: The FMHP series uses Seal #200 (Part Number: 92500150). It is a compact, unitized, single spring elastomer bellows mechanical seal with both a carbon ring and ceramic ring assembly. �� Downloads & Resources �� Gecko Aqua-Flo Flo-Master HP/CP Techbook (PDF) – Official installation manual, assembly/disassembly instructions, troubleshooting guide, and replacement parts list �� Why Choose the Gecko Aqua-Flo FMHP 1.5 HP ✅ Industry-leading flow rates – Up to 150 GPM from the unique high-performance impeller ✅ Dual-speed versatility – Powerful jets on high speed, efficient filtration on low speed ✅ Proven reliability – Gecko Alliance’s 25 years of spa pump engineering expertise ✅ Easy installation – Quick-release compression fittings included; rotatable wet end for flexible plumbing ✅ Built-in protection – Thermal overload protection safeguards the motor ✅ Durable construction – Reinforced plastic volute, stainless steel fasteners, elastomer bellows seal ✅ Massive cross-reference list – Direct replacement for 80 Aqua-Flo FMHP model numbers ✅ Lower operating costs – Superior flow rates at lower HP means less energy consumption �� Why Buy from Parts4Tubs ✅ US-based support for American customers (Boca Raton, FL) ✅ Fast shipping across the United States ✅ Expert advice from spa and hot tub specialists ✅ Competitive pricing in USD ✅ Full warranty support ✅ Hassle-free returns ✅ Replacement seals, impellers, wet ends, and parts available ✅ Dedicated customer service team — real people, not just the internet ✅ Compatible AMP cords and pump unions available separately ✨ Summary The Gecko Aqua-Flo Flo-Master FMHP (02115000-1010) is a 1.5 HP, dual-speed, 115V jet pump featuring industry-leading flow rates up to 150 GPM from its unique high-performance impeller design.

O-ring gaskets may vary between manufacturers - measure your existing gasket for accuracy. 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: 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. 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) 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. 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. 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. 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. 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. 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. 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. 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. Turn On the Power: Restore power to the hot tub by switching on the circuit breaker or reconnecting the disconnect switch. 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. Refill the Hot Tub: Once you've confirmed that the new pump is functioning properly, refill the hot tub with water. 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. 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: 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. 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. 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. 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. 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.
