What is the concept behind a gizmo? Should I buy one and use it instead of the old rubber plugs the previous owner left? What's its advantage?
And how do I work those rubber plugs? I'm guessing I loosen the screw, plug the plug into the skimmer or return jet, and then tighten the wing nut. Is this to ensure they don't fall out? How tight should I turn the screws?
