Want to swim without turning at the wall, counting laps, or stopping every 25 yards?
With swim jets, your backyard pool transforms into an endless current that you can swim against. You control the speed and resistance, so it feels like open-water swimming.
But what should you know before you invest in one? Here's everything covered.
What Are Swim Jets?
Swim jets are motorized systems that mount to your pool and create a strong, steady current. Think of them as a treadmill for swimming. You swim against the flow and stay in one spot while getting a full workout, no matter how small your pool is.
Core Technology
The system pulls water through intake ports and pushes it back through directional nozzles, creating a smooth current that mimics open-water swimming. Most units feature variable speed controls that adjust from gentle flow to intense resistance.
A complete setup includes the pump motor, intake fittings, discharge nozzles, control panel, and plumbing connections. Premium models add digital controls with preset programs plus accessories like underwater lighting or music sync.
Popular Applications
Fitness enthusiasts get unlimited swimming distance without pool length constraints. Families gain entertainment options for all ages. Physical therapists prescribe them for controlled rehab exercises.
The technology fits pools of different sizes. Even compact 12-15 foot setups accommodate effective swim jet systems, making them practical for city homes with limited outdoor space.
How Do Swim Jets Work?
Swim jets operate on continuous water circulation to create resistance. Smart engineering and hydrodynamic design transform your pool into an endless swimming experience.
Water Circulation Process
The pump draws water through intake ports while the motor accelerates it through specialized nozzles. These nozzles shape the water into a wide, smooth stream covering your entire body.
Advanced designs create fan-shaped currents that distribute flow evenly across the swimming area, eliminating turbulence and maintaining steady resistance throughout your stroke cycle. The experience closely mimics open-water swimming.
Control Systems
Speed controls adjust current strength for different needs. Low settings suit gentle exercise or children's play. High settings challenge competitive swimmers with flows reaching 1,000+ gallons per minute, maintaining steady, turbulence-free resistance.
Modern systems offer multiple operating modes. Free-swim modes maintain constant flow for extended workouts. Interval modes alternate between high and low resistance for structured training. Advanced models simulate wave patterns for added variety.

Swim Jet Types: Which One Is Right for You?
Four main types exist, each suited to different situations. Choose in-ground if you're building a new pool or training seriously. Pick retrofit for existing pools. Go portable if you're renting or testing the technology.
Here's what sets each apart.
| System Type | Flow Rate Range | Installation | Best For |
| In-Ground Integrated | 400-1,100+ GPM | Professional | New construction, serious athletes |
| Retrofit Units | 300-600 GPM* | Moderate | Existing pools, regular users |
| Above-Ground Compatible | 200-400 GPM | DIY-friendly | Vinyl pools, budget-conscious buyers |
| Portable Systems | 100-300 GPM | No installation | Renters, seasonal use |
* Flow rates represent typical industry standards. Advanced retrofit systems like iGarden's P230 deliver up to 1,100 GPM with deck-drilling installation, matching in-ground performance without pool reconstruction.
In-Ground Systems
These get built right into your pool wall when you're constructing a new pool or doing a major remodel. The pump sits in your equipment room, and pipes run underground to wall-mounted jets. You get the strongest, smoothest current with nothing cluttering your pool deck.
Athletes love these because they deliver consistent, powerful water flow. Everything's hidden and optimized for performance. You'll need professional installation, but the result looks clean and works perfectly.
Retrofit and Modular Solutions
These bolt onto your existing pool without tearing anything apart. You mount brackets to your deck or pool edge, position the pump nearby, and you're done. They cost less than in-ground systems and work great on concrete, fiberglass, or vinyl pools.
Popular choice when you want to upgrade an older pool. You can access the pump easily if something needs fixing. Modern versions look sleek and perform nearly as well as built-in systems.
Portable and Above-Ground Systems
These hook over your pool edge and plug into a regular outlet. That's it. No drilling, no construction, no commitment. They work on any pool—in-ground, above-ground, vinyl liner, whatever you've got.
Great if you're renting, using a pool seasonally, or just want to try before you buy. You can unhook them and move them in minutes. but they still create a solid current for swimming laps and staying fit.

How to Install Swim Jets in Your Pool?
Installation depends on your system type. In-ground systems require professional contractors and take days. Retrofit units need moderate skills and take hours. Portable models install in minutes with no tools.
Here's what each process involves.
Professional Installation Process
- Site Assessment: Contractors measure water depth, check structural integrity, and identify optimal equipment placement to maximize current effectiveness while maintaining aesthetics.
- System Integration: For integrated systems, contractors select the wall location (typically opposite the shallow end, 18-24 inches below the waterline), cut nozzle housing openings, and run plumbing to the equipment area. Pumps connect to dedicated electrical circuits with GFCI protection per code.
- Testing and Calibration: Teams test for leaks, calibrate flow direction, and program controls through pressure testing and flow verification. Installation ranges from a few hours for deck-drilling systems to several days for complex in-ground integrations.
Planning Considerations
- Electrical: Most systems need a dedicated circuit. Always check local building codes; permits may be required.
- Site Access: Ensure contractors have a clear path to deliver equipment. You may need to temporarily modify landscaping or fencing to create workspace.
DIY Installation Steps
If you are installing a retrofit or portable system yourself:
- Mount Brackets: Secure the assembly to a stable surface according to the manual.
