Counter Current Units
A counter current unit is a high volume pump providing a flow of water from outlets along one side of the pool offering a similar sensation to swimming against the flow in a mountain stream. Swimming against the current offers all the benefits of a full exercise swim without having to move an inch.
Counter Current Units
Counter Current Units are a great way to get more from your swimming pool, particularly if you want to swim for exercise but don't have the space for long swimming lengths.
Also known as swim jets or counter current systems, they create a strong, directed flow of water through the pool. You swim against this flow, allowing you to keep swimming in one position rather than reaching the end of the pool, turning around and starting again.
They can be used in swimming pools of all sizes, but they're particularly useful in smaller pools where traditional length swimming isn't practical. Depending on the unit you choose, the water flow can also be adjusted to suit different swimmers and different types of exercise.
Why choose a Counter Current Unit?
A counter current unit can completely change the way you use your pool. Rather than needing a large pool for a proper swim, you can exercise continuously within a relatively small swimming area.
- Swim continuously without having to turn
- Make better use of a smaller swimming pool
- Add resistance for swimming and exercise
- Use your pool for regular fitness and cardiovascular exercise
- Enjoy lower-impact exercise in the water
- Add another useful feature to a family or leisure pool
When should a Counter Current Unit be installed?
This is an important consideration when choosing your unit, as some systems are designed to be incorporated into the swimming pool during construction, while others can be fitted to an existing pool.
Installing during a new swimming pool build
If you're currently planning a new swimming pool and know that you would like a counter current system, this is generally the best time to allow for one.
Built-in Counter Current Units require components to be incorporated into the pool wall, together with the necessary pipework, pump and electrical requirements. Planning for these during construction gives you a wider choice of systems and allows the finished unit to be neatly incorporated into the pool.
Installing during a pool renovation
Renovating an existing swimming pool can also be a good opportunity to add a counter current system. If work is already being carried out to the pool shell, surround, plumbing or plant room, speak to your pool installer about whether a built-in unit could be included as part of the work.
Adding a Counter Current Unit to an existing pool
Already have a finished swimming pool? You still have options.
Retrofit and over-the-wall Counter Current Units are available for certain swimming pools. These are designed to add a swimming current without the same level of structural work required for a traditional built-in system.
The best option will depend on your pool construction, the space available around the pool, electrical requirements and the type of swimming experience you're looking for.
Choosing the right Counter Current Unit
Not every counter current system feels the same to swim against, so it's worth thinking about what you actually want from your pool before choosing a model.
If the unit will mainly be used for occasional exercise and family swimming, you may not need the same performance as someone who intends to use their pool regularly for fitness or swim training. Look at the flow rate, available adjustments and installation requirements of each unit when comparing your options.
For built-in systems, you'll also need to consider where the pump and associated equipment will be located. Checking this before purchasing can save problems later in the installation.

Counter Current Units FAQs
What is a counter current system for a swimming pool?
A counter current system uses a pump to create a strong flow of water across the swimming pool. You swim against the flow, which means you can continue swimming while staying in roughly the same position in the pool.
Think of it a little like swimming against the current of a river, but with the flow created and controlled by your swimming pool equipment.
Is a swim jet the same as a counter current unit?
The terms swim jet, counter current unit and counter current system are commonly used for products that create a flow of water for you to swim against.
Individual systems can vary considerably in their power, water flow and installation requirements, so it's important to compare the actual specifications of each product rather than relying on the name alone.
Can a counter current unit be fitted to an existing pool?
Yes. Some Counter Current Units are specifically designed for existing swimming pools. Retrofit and over-the-wall systems can provide an alternative where installing a traditional built-in system isn't practical.
Which options are suitable will depend on the construction and layout of your swimming pool.
Is it better to install a counter current unit when building a pool?
If you want a built-in counter current system, planning for it during the original pool build is usually the most straightforward option. The fittings, pipework, pump position and electrical requirements can all be considered as part of the swimming pool design.
If your pool is already built, don't worry – retrofit options may still be available.
Do Counter Current Units work in small swimming pools?
Yes. This is one of their biggest advantages. A Counter Current Unit allows you to swim continuously without needing a long pool for traditional lengths, making it possible to get a good swim from a relatively compact swimming pool.
How powerful does my counter current unit need to be?
It depends on what you want to use it for. Someone looking for gentle exercise or recreational swimming may prefer a different flow to a stronger swimmer who wants to use the pool regularly for fitness or training.
Check the flow rate, adjustment options and manufacturer's specifications for each unit before making your choice.
Where is the pump for a counter current unit installed?
This depends on the system. Many built-in Counter Current Units use a separate pump positioned close to the swimming pool, with pipework connecting the pump to fittings installed within the pool wall. Retrofit systems may work differently.
Always check the installation instructions for the individual counter current unit before ordering, particularly if you're working with an existing pool.
