Not normal for that to happen but the jet faces on the two back jets may be turned off or down.
Try turning the face of the jet clockwise and see if you get more water flow out of each jet.

They are serial number specific, so be sure you know which one you have.

The trim for any brand whirlpool (w/p) tub must be ordered from that specific tub manufacturer. They will need to know exactly what your particular model is.

The model of your w/p tub, and serial number, is most often, but not always, located on the motor end of your unit but not on the motor itself. Access to this end of the tub, if installed to code, should get you the information you need, otherwise you are out of options'

Go to Jacuzzi.com and plug in model and serial no. you should be able to find an operation manual there.

Did you check inside the cover of the control box. Most spa's have a schematic of their components there. Hope it is there.

call the manufacturer Asteria Bath Company at1-800-288-4002 and they can send it to your email address.
