Tusa R-100 First Stage

The tech specifications state 2 H.P. ports and 4 L.P. ports. All are present and accounted for. But, there are also 2 E.P. ports. What are those?

EP for "environmental ports" In other words.. that's the hole that lets in the water for the ambient pressure.

Ahh . . . thanks Larry. The EPs appear to be removable. Under what circumstances would they ever need to be removed?
