New inground pool build. All of the spa jets have good water pressure with the pump running. Once the blower is engaged, one of jets doesn't have any air pressure. We have had the plumber out to inspect the 1" line inside the plumbing internals and he reseated and tested. That was not the issue. We also removed the jet fitting and replaced with another fitting and have the same issue. Any suggestions on what may be causing only one jet to malfunction?

Usually, the issue is a blockage in the jet. Remove ALL of the fittings AND nozzles and run the pump without them installed, it may flush the lines of debris.

What kind of jets do you have (e.g. standard venturi tees, PolyStorm, etc.)?
