I think we all are interested to hear what your PB says when he views the setup that the plumber did and what his next steps are.Thanks all for the feedback! A wealth of knowledge! Happy Holidays!
From the photos it appears his check valve and diverter are both Pentair so he should be good to use what's there on both pumps.A diverter from the same manufacturer as the check valve should be used.
You have a Pentair 3 way diverter in front of the CV by the pump.
If that CV is a Pentair then you need to get a Pentair 2-way diverter, if Jandy then a Jandy 2-way diverter.
WTH!WBW, speaking of unexpected freezes; this was my greeting this morning. You'll get a kick out of it.

Yeah, just looked at the weather online, in the high 20’s at night.It looks like it could dip into freezing weather starting on the 21st. It's a long range forecast, but I just drained my irrigation RPZ valve and covered it. I drained the RPZ on the autofill as well (not covered).
