I searched for the terms, but didn't see anything on this, so hopefully I am not duplicating.
When my booster pump is running, if I put my hand in the water, directly above the vacuum port, I can tell there is quite a bit of air escaping from behind the plastic/rubber fitting.
A couple of questions:
1. Is this a repair job, or do I need to replace something (vacuum port seal maybe?)?
2. Can this be done with water at or above the port level, or do I need to drain down below to work on it (not a problem as my stabilizer levels are currently crazy high right now, and I will need to drain 75% at some point according to calc)
