[Resolved] Reservoir leaking from top hat grommet – is there an easy fix?

First time using my brand new Autopot 4 pot system. While preparing to turn the system on, I discovered that the reservoir is leaking from the grommet. Are there any tips for resolving the leak (that is, without assuming that the grommet itself is faulty? I had some concerns upon setting up the system that the grommet looks quite fiddly and would likely leak…but hey, I remained hopeful.
