Your spa may be fitted with one or more water flow diverters.
These diverters control the flow of water from each jet pump between various zones of the spa. You can have full pressure in one zone and no pressure in another zone.
Turn the diverter handle all the way to the left or right, or part pressure in each zone by setting the diverter handle to the middle position.
NOTE: It is important NOT to push these diverter handles past the natural stop point as breakage is not covered by the spa’s warranty.
