Air tub never worked from day 1. Call support and they insisted tub was installed wrong. No way for me to verify without tearing bathroom apart again. Finally had to fix it to sell my house and found that the air switch/tube was defective all along. Two small buttons in bottom of tub covering air ports came off immediately after installation. After a few years, a couple more broke and none of them would go back on. Called and asked for more buttons thinking they would cost $2 - $3 but they charged me $30 for them and then posted to my credit card a charge of $300 which I'm now having to dispute/correct. Get your tubs somewhere else.
