If I replace two ball valves with one Jandy valve I’m not sure if I will be able blow out lines during fall closing. Normally I use a compressor to blow the lines. I blow the skimmer line and close the ball valve when complete. Then I blow the main drain until I see bubbles coming up and then close the main drain ball valve. If I replace the two ball valves with one Jandy valve will I be able to blow both the skimmer and main at the same time and then close off the Jandy going to the pump?
pic attached shows what I have planned.

If I’m following, a 3-way valve can open both output sides at the same time, or only one of the two sides. So there shouldn’t be any difference from that standpoint.
 
Depends how strong the blower you use is.

Do you use a Cyclone blower at closing?

Magiteck, but I wouldn’t be able to close them off after I blew them out with air. I guess though the skimmer shouldnt have any water return back to it.
