Question:  I have a jucuzzi quantum with Silent air induction system only one of the jets is pushing air bubbles thru the jet, i bought a new air control check valve for two of the jets but they still do not work. any ideas of what i may be doing wrong?

Answer:  This is a problem usually seen in spas but can happen in whirlpool bathtubs if the clamping rings warp or become loose inside the jet.  If the jet nozzles are loose water will be forced around the outside of the nozzle where it sits inside the jet. This water will be forced into the air lines preventing the jets from drawing air in. This is a common problem on spas where bromine is used as the sanitizer. The bromine actually erodes the plastic nozzle. In most cases the nozzles along with the clamping rings and gaskets can be replaced and this solves the problem.  In rare cases the entire jet may need to be replaced.
