Pool newbie

Typically, a valve like that has a gate that is positioned opposite the handle, so that the port the handle points to is closed. If this is correct, and you move the handle 180 degrees from the position shown, you'll close all flow to the pump.

Regarding the solar loop, currently it appears 100% of your water flow goes through that loop, so closing the valve would (again) stop all flow.

. . . I think you need to hire a pool service guy to come out and show you how to operate your pool. You aren't likely to get very good results trying to work it out here.

True, was thinking the same also. Getting someone to show me.

Wow, I was searching online for certain pool issues and came across my own post from 6 years ago.

I'll update shortly with new images and of course another set of issues LOL
