Standard JetStandard Jet

The adjustable flow directional designer jet is Hydro Systems standard whirlpool jet. The direction of each jet is easily adjusted by pointing the nozzle in the desired direction.

• Whirlpool Jets:
Swirling JetSpinning Jet Pattern
- Swirling Adjustable
The adjustable flow swirling designer jet is a popular upgrade from the standard designer jet. Instead of pointing the nozzle in one direction, the nozzle spins to provide a swirling, massaging flow of water. The amount of flow can be adjusted by turning the escutcheon. The swirling designer jet is also 2½" in diameter and is available in all of the same colors and plated finishes as the standard designer jet.

Jumbo JetStandard Jet
- Jumbo Jet
This optional extra large therapeutic jet was adapted from the outdoor spa industry and adds new dimension to hydro massage bathing comfort and enjoyment. It has a higher flow rate than the standard jet, but with less velocity. This jet can be easily directed by pointing the nozzle towards the desired location for a soothing, gentle massage. The amount of flow can be adjusted, but not turned completely off, by turning the insert. This jet is just over 3" in diameter and is available in many popular colors or with plated metallic trim.

Large Rotating JetSpinning Jet Pattern
- Jumbo Rotating Jet
This extra large spinning therapeutic jet was also adapted from the outdoor spa industry. Similar to the swirling designer jet, the jumbo rotating jet provides a spinning, massaging action. Turning the insert adjusts the amount of flow, but unlike the standard and swirling designer jets, does not turn the flow completely off. This jet is just over 3" in diameter and is available in the same popular colors and plated finishes as the Jumbo Jet.

6 Back Jets
- Back Masseuse
Back pain is the second most common reason people in the U.S. visit the doctor each year.
Millions of people suffer needlessly from back pain. With Hydro Systems' Back Masseuse, you can end that nagging pain and enjoy increased flexibility. You'll enjoy a measurable reduction in pain through intensive hydrotherapy focused on your back and spinal column. Using six strategically located jets, our Back Masseuse is designed to heighten the therapeutic effects of hydrotherapy.

Spining Back JetSpinning Back Jet
Back Masseuse System 1
These jets are available with the Back Masseuse System 1 and are installed in a series of 6 jets operated by a single volume control. A pulsation massage is creating by the swirling action of these jets, providing greater relief than a single jet.

Pin Point JetMicro Jet
Back Masseuse System 2
These jets are available with the Back Masseuse System 2 and are controlled by an electronic keypad. This 6 jet series offers direct flow onto your back. The electronic keypad directs the jets to operate in a Shiatsu pattern utilizing only two jets at a time, as well as the speed of transition from one pair of jets to another.

Water Jet Neck Pillow
- Neck Masseuse
The neck is the body's most vital passageway. Circulation through this small region is key to relieving muscle tightening. Muscle tightening is the result of accumulated stress and poor circulation. Each negative aspect works on the other to create discomfort. The Neck Masseuse is designed to increase circulation and relax muscle tension. The Neck Masseuse sends hydro massaging water onto the neck.
You select the pulse level. Level one is subtle and sleepy. Level two is attention getting and soothing. Level three is intense for maximum stress relief.
The optional neck masseuse pillow jets can be turned on any time the whirlpool pump is running. Press the pillow key once to turn on the pillow jets. Press the key again to turn them off. To adjust the speed of the pulsating jets, press the pillow key and hold it down until the red "mode" light comes on. With the light on, you can adjust the pulse to any of three speeds. Press the minus key to slow the pulsing, press the plus key to increase it. The red mode light will remain on while you are adjusting the speed, and will turn off automatically fifteen seconds after you've finished.
