If your skimmer has two lines/pipes in it do you use two? Or one regular plug and one gizmo?

The Gizmo protects the skimmer from water freezing, expanding, and cracking the skimmer. It is not there to protect the lines running to the skimmer. You only need one to protect the skimmer itself. You do need to plug both of the holes in your skimmer, however. So a gizmo in one (it doesn't matter which one) and a plug in the other.

Can you add anti-freeze to this Gizzmo?

No, it’s solid plastic. It works, no need for antifreeze.

Can i blow out the water from lines when this is on?

I don't know what the guy who answered this before in 2016 is talking about but, you blow your lines and one at a time you plug the line that blow in order. when the skimmer line blows you screw in the Gizzmo instead of a plug. Works fine. No Problem...

Why cant you use these for multiple seasons?

We've had a 4101 forever - could have been 20 years. It just broke this season.

Fits an offset skimmer drain hole!!

The gizmo is the best! I bought 2 different ones at a local store and based on where the the hole was in the drain, they would t quite fit. So, if you have an offset drain in your skimmer, this works perfectly!
