I have a manual for servicing the pool filter. I'm afraid I might mess something up because what I see
is not what I am expecting.
I'm expecting a check/shutoff value to the rooftop solar so I can open the filter without water pressure
as the entire roof empties.
Something like these:

expected: with valves

again expected with values

and again with check value
What I see is more like this:

3 way valve instead of check value
There are good valves installed, jandy valves, but they don't have an off position for the T plumbing:
Water in bottom out both sides
Water in bottom right side closed
Water in bottom left side closed
Note there is no both sides closed.
1- are one-way valves normally installed so this won't happen?
2- it doesn't matter, because the pump will pump air until the water starts flowing
3- do I just open the relief valve til all the water empties, service the filter, reassume, turn on
and hope it works, or
4- forget it bud, spend a couple hundred and get a pool contractor out there
Thank you all for any wisdom
