Pump plumbing dilemma

I am replaceing a very old wfds-8 whisperflo 2 hp with a newly bought intelliflo pump. I had earlier thought about replacing the backend only....however the volutes are different as my whisperflo is from prior to 1998.

My problem is that whoever set up the pump earlier did not leave any extra PVC pipe to cut and attach a new coupling. There is literally less than 1 cm between couplings all the way to the filter valve (MPV). There is one 2" slip PVC Union in between the discharge and the filter line.

Question: How does one redo the pumbling when there is no room to attach a new coupling or extra segment of PVC. Any previous ideas or experience? I thought about replacing one half of the slip union, but I am not too sure If I can buy the exact same type and brand?

Thanks very much for your time

With a coupling to the left of the union and in the vertical it looks like something was repaired once which eliminated the extra material.

I'd sure see what unions are available but ran into similar situation where the diameters were different and could not be interchanged.

The box to the left where the pipe terminates, that a glued joint?

Just realized that it possibly is a screw in joint (the box you referred to is a multiport valve). I will have to check the manual again to make sure.

The issue also is that it has been around for over 10 years, and I am not too sure if it will unscrew easily or something will snap and break. If the multiport valve cracks, I am looking at more headache and more $
