I want to try to use threaded plugs this year instead of gizmo for my 2 skimmers. My only concern is the other purpose which the gizmo provides, which is ice expansion protection. In each skimmer, I have 2 threaded holes....one that goes back to the pump and the other is just blocked off and goes no where. I am able to screw a gizmo into the dead end hole so I am thinking about using the threaded plug to plug the skimmer line and just screw in a gizmo into the other hole for ice expansion protection. Anyone do this or see any problems with it?
The reason I want to try the threaded is because I feel like I get a more secure connection with the threaded plug than I do with the gizmo.
