Hole in mouth of skimmer

[Water Cat]

For some reason there is a hole with a rubber plug in the upper right hand corner of my skimmer's mouth. I don't know what purpose this hole serves. Has anyone seen anything like this before?

My skimmer looks like this one hole is in the upper right hand corner with a rubber plug.

It's for future overflow purposes. You can run a small tube/hose from it out to the yard nearby and it will keep itself no higher than that level.

Ah that's an interesting feature. I've never seen a skimmer with an overflow hole before.

Usually it just spills out the lid until you set the pump to waste.

I guess this would be for heavy rainfall?

Perfect for that. This one is pretty wide too which is nice. We had a member somewhat recently that had a small hole and it just couldn’t move enough water to matter.
