I'm about to pull the trigger on a Pentair 011533 WhisperFlo VST pump 2.6HP to replace old bessie which was a 0.75HP single-speed. The problem that I am foreseeing though is the inlet looks to be threaded onto the valve. All of the videos I've seen include them sawing off a portion of the inlet PVC but in my case there is 0 amount to do so. I'm unsure how to remove the pump without rotating it to unthread it. I've attached some pictures of the situation.
Need advice on how to install a new WhisperFlo

The pump installer did not do you any favors!!!!
In theory you should have about 18" or so between the valve and the pump.
You never, ever, want to install a $1,800 pump without using pump unions.. Like this...
The current pipe between the valve and the pump is screwed into the pump, but I suspect it is glued into the valve.
It that is 2" plumbing, then a 2.5" adapter should fit over the outside the existing valve.
Thanks,
