Hi all, recently got my pool redone including new plumbing/filter/pump. I think it's time to backwash my Pentair QuadDE 60, but I don't have one of those wonderful valves with a dedicated "backwash" setting, which seems to be what's shown in all the stuff I've read so far. I've attached photos of my set-up. How would I go about backwashing this puppy? You'll see that, to dummy-proof our plumbing apparently, our builder took off the handle from one of the valves. I'll be fine putting it back on.
Thanks all, as always.
