Spa & Swim Jets

Spa & Swim

Enjoy the low impact benefits of exercising in water.

  • A swim jet is a strong flow of aerated water, usually in the end of a pool that enables a swimmer to swim continually even though the pool may be only 5m long.
  • An electrician provides additional electrical power supply to the pump site which are usually located with the filtration equipment.
  • There is a wide range of quality, price and performance.
  • Some low priced small systems may give you a weak water flow and be unsuitable for an adult.
  • For example two x 1.5hp pumps and nonadjustable pool returns are cheap but almost useless.

If you are a serious swimmer and require unlimited distance swimming consider the BADU Stream swim jet system.

  • A Badu can create a flow of 2400 litres/ minute.
  • Powerful pumps, usually two x 4hp pumps, force the pool water through specially designed nozzles. The flow is adjustable and controlled from within the pool.
  • Price to supply and install may be $8000+
  • The Badu jet system and nozzles are built into the concrete pool shell at concrete stage.
  • The Badu system looks like two dinner plates in the end wall when it is not operating.
  • The water stream flow direction and performance are adjustable.
  • A massage attachment is also included with the Badu system .
  • Alternative aftermarket systems are available from $10000 and the equipment sits on the pool edge.
  • Some swim stream models do not aerate the water which suits swimmers who do not want bubbles in the flow.

I suggest a google search to be fully informed.

Spa jets
  • Water driven spa jets are usually located in the pool wall at a height that enables people to sit in front of the jet.
  • The jets are best located on a seat or ledge around 500mm below water level.
  • The most popular massage spa jets are aerated by a venturi air inlet that mixes air from the atmosphere with water pushed by a high performance pool pump.
  • A guide to pump size is one quarter horse power per jet so eight jets can be well serviced by a 2.0hp pump.
  • You can have multiple jets but the pump size will be critical to the spa performance.
  • When spa jets sets are located at different depths it is best to have a separate pump for each set to overcome the variation in water pressure at the jet.
  • Please consider pool heating if you are planning to have spa jets.
  • Most people find that sitting in front of a cold water spa jet is not pleasant.
  • An eight jet set with 2.0hp pump is available around $3000.
Air tracks and floor jets
  • Jets driven by air pressure create a bubbling appearance to your pool or spa.
  • In concrete pools an air track pipework can be built into the concrete floor at the concrete stage. The pipes are continued to the filtration area.
  • Careful marking of the pipe location on the floor is required because the pipes will be drilled with holes after plaster stage.
  • A high performance air pump called a blower is attached to the pipes at the filtration area.
  • Air is forced though the small holes and the effect provides massage for the people.
  • An upgraded system uses special nozzles called pepperpots and they look like pepper shakers in the floor.
  • A set of twelve pepperpots and air blower is approximately $1500.
  • Children especially enjoy this feature as it fill their costumes with air bubbles and blow little boats all over the pool.
Typical concrete spa set up
  • Concrete spa pools can be almost any shape and size.
  • A concrete spa pool 2.5m x 2.5m can be designed with seats and ledges and can easily cater for a group of up to eight people.
  • One set of eight venturi massage jets and one set of twelve pepperpots is a popular specification.
  • Spa heating is essential for all year use of your spa.
  • Gas heating is the first choice because of the rapid heat up time.
  • It is possible to select a gas heater that can heat the pool and the spa and have the temperature different in the pool to the spa.
