What do I do when fitting installed backwards causing poor performance?

Airflow/TAB Impacts From InstallationV136 field-polished — distinct TAB/airflow answer

A backwards fitting can fit perfectly and still perform badly. Verify airflow direction and fitting orientation before sealing.

Field checklist

This fitting may be backwards at [location]. Can you verify airflow direction and fitting orientation before I seal it?

Do not assume symmetrical-looking fittings work either way.

Some fittings are directional. Backwards orientation can create turbulence, pressure loss, or wrong branch performance.
