How To Fix An Airlock In A Hot Tub?

One of the most common tech support calls we get is “How do I fix an airlock?”, in this article we’ll go over some of the more common solutions to this problem.

Understanding What An Airlock Is

If you’ve just filled your hot tub with fresh water and now the jet pump isn’t working, there’s a good chance you have an airlock in the system somewhere. Essentially what an airlock is, is a big bubble of air that’s trapped somewhere in the pump that needs to be “burped” out, not unlike burping a baby. Until this air bubble is worked out, the pump won’t be able to move any water.
