What is an airlock in a hot tub?

An airlock in a hot tub occurs when air becomes trapped in the Plumbing system, preventing water from flowing properly. This can lead to reduced water circulation, ineffective heating, and potential damage to the pump. To resolve an airlock, users often need to bleed the system by opening a valve or using the jets to release the trapped air. Regular maintenance and ensuring proper water levels can help prevent airlocks from occurring.
