Correct Sequence to Repair PVC Pool Piping

I have a 3 foot section of 1.5" PVC in my pool plumbing that I need to replace. It's a tight fit, so I'd like to get advice on the best way to tackle.

The left side of this run is fixed (the elbow is glued onto the section of pipe coming out of the valve).

The right side is connected to an adapter going into the pump housing and is removable (male-threaded adapter).

As you can see in the picture, the union is not effective because the two runs of pipe are not at the same height.

I am planning on removing and replacing everything from the union to the adapter, but I want to do it in the right sequence to allow for enough room for a clean fit.

Should I follow the same approach as shown in the picture (adapter to 45 degree to 45 degree to union), or is there a better way to configure this?

Cut near the red line. Scrap everything to the right.

You can use 45's or a 90. Either will work.
They may have used street fittings which connect into each other.
You will need a union in the line.... probably at the red line.
You need to add some pipe between the pump and fitting(s) so that the union lines up correctly.

It would be much easier if I could use a 90 so that I have fewer things to align. This is a 1/2 HP motor pump, so I assume that the pressure going into a 90 wouldn't be an issue.

Thanks for the help with this!

There is a 90 on the left side.
The two 45's may have a little smoother water flow but the 90 will still work ok.

I agree with Pete about removing everything to the right of the red line.

I would use two 45's if possible. It's not that much more effort and will help with the flow out of the pump.

I would assemble it from left to right. The last connection would be the short vertical pipe (or street 45) into the male threaded fitting. You'll have some vertical wiggle room, but no horizontal. So you can assemble everything, then measure that 1-3" vertical pipe, and glue that last.
