Daren, sorry I missed this before the job was done The job looks great! You could have used a 2" 'street 90' off of the flow switch tee and then reduced that to the 1.5" flex and saved 2+" on the length. The street 90 has a regular socket on one side but the other is a 'slip' end and will go into any other 2" socket (like the out port of the flow sensor fitting).
I'm only offering this for the same reason you started this post, to let the next person who does it know that these fittings exist and that they may make a 'tight' set up a little less tight
