Hi there,
I have an AGP that I currently use with two pump/filters in a fairly basic layout.

The above setup works fine, but there are times where I really want to pull from the "OUT" ports into the larger pump that has a bigger/better filter and just run it that way for a while. Currently to achieve that I have to disconnect the skimmer from the large filter and disconnect the OUT pipes from the medium pump and then run the OUT pipes into the larger pump, leaving the skimmer hose kinda awkwardly draped over the skimmer. If it fell, the pool would start to siphon, so not ideal.
What I'd like to do is have a valve setup that would allow me to choose where the large pump pulls from and also allow my current setup to continue. So I'd be able to run the large pump/skimmer and heater at the same time OR I could turn off the heater and just run the large pump from the OUT ports to the main return so I could clean more of the water that's down deeper instead of pulling from the skimmer.
Sort of like this:

If my thinking is correct, I need 2x 3 way valves that would allow me to A) send the OUT water either to the Medium pump or to a second valve and B) the second valve would allow me to choose between pulling from the first valve or the skimmer and send either one back to the return.
I think I'd use a couple of something like this? If the three visible outlets on that valve were labeled A (left side), B (center), C (right side) do they work like A-->B or C-->B pulling from either of the two "side" inputs and always pushing out the center one? If so that makes sense to me but I admit I don't know how these 3 way valves work.

Then I guess I'd need 6x this

And 6x this

With some 1'5" PVC between the valve and the slip fit with female NPT adapters that would then screw into the intex adapters, allowing me to connect all my 1.5" intex stuff.
Sanity check very much appreciated!
I have an AGP that I currently use with two pump/filters in a fairly basic layout.
- The larger of my two pumps pulls from a Hayward through-wall skimmer and dumps directly back into the stock return
- The medium sized pump pulls from the 1.25" "B" outlets that merge together (like a lot of AGP's) into a 1.5" tee connection. That runs to my BBQ heater and then just dumps via a 1.25" pvc pipe directly back into the pool, over the side
