You can also enlarge the existing hole to a 2.5" fitting use a splitter to 2 filters and go back to 2" from the filters to the wand.Ok man I’m learning haven’t been in the game 1 year. So pardon the elementary type questions I have.
If one were to add a second 2” vac hole (port?) after drilling the hole what steps and what fitting would best be used and how to seal it?
I’ve never done this.
