You need to fully seat the couplers / fittings.
This raised edge is the stop, so double its measurement. You can also mark it on the outside of the flowswitch, then hold that near the pipe in order to transfer the cut marks.
Salt level 3600 last week and 4000 today! Causes?

But what if it doesn't seat easily? What is best technique? I can hammer it but the twist seems real hard.
It will once it's primer/glued. It will easily melt itself up in there.
I push dead on then twist just a little, about a half inch.
So the primer glue will make it possible for me to do this, ie seat it fully, pronto! before the glue dries on me! Thank you

What size pvc are you working? 1-1/2 pvc pressure fittings will allow about 1-1/4 inch of pipe into each side of the fitting. Measure it or mark it like NewDude. Or for the T - if it’s 1-1/2 inch measure the overall length and subtract 2-1/2 and that’s how much you’d cut out of the pipe.
Primer and glue will make it slide like butter. Don’t forget to clean the pipe with cleaner first and give the fitting a 1/4 turn as you seat it if you can.

Just plug the old flow switch T. Use Teflon tape on the plug and be gentle when screwing it in. Old pvc likes to get brittle from the sun.
Trying to install the Neverlube valve in the blue area may be very difficult if the pipe is tight to the ground. The bottom housing of the Jandy valve sits lower than the gluing port, so you would need some clearance below the pipe for it to fit properly.
I am using 2 inch pipe for the T connector for the flow switch. Also using 2 inch for the Jandy valve with is a 2.5 inch valve.

From memory I believe the stop depth on 2” is 1-3/8. Best to measure to double check - I see more 1.5” day to day that’s why it’s solidified in my brain!
Not going to finish today. Reached into my bag and forgot to close the PVC cutter. Razer sharp and yeah! I messed up but I'm sure I don't need stitches. The T cell that I will be installing has an arrow and I am pretty sure it should face the SWG that I have in the red circle.....right. Also can I use nail polish remover to clean the pvc or do I need "pvc cleaner"".

Sorry to hear about your hand! Thats No good! Do you mean the flow switch where you’ve said T cell in the above quote?
The flow switch in the T that I intend to install. The PVC T has an arrow showing how flow goes so I guess I am asking is the flow going to the SWG and should I point the arrow to the SWG
the machine LIES. i promise. Put it through a lie detector test via the test kit mentioned above and you will see!

The arrow should point in the direction of flow. Memory serves the pipe coming from the ground is coming from a heater to your SWG and flows back to the pool from there. So yes. Typically there is also an arrow on the flow switch indicating the direction of flow, and it should point towards the return direction so the switch collapses properly in the flow stream.

It’s most important you orient the switch the correct way. The arrow on the T is a helpful reminder but make sure you orient the switch in the way that it collapses in the direction of flow. Can’t wait to see your completed job. 
I have a technical question about cutting this pipe which starts at ground level and then slants up to meet the filter. I know I have to cut the pipe perpendicular ie perfectly perpendicular in preparation for inserting the Jandy valvue. I am concerned I may make a mistake by just taking a hacksaw to it in terms of the ends not being perfectly flush. If this was lying on the ground I would not have the same concerns. What is the best way to do this perfectly or must I just eyeball it?
Secure a zip tie to it nice and perpendicular. Mark the edge with a sharpie then cut the zip tie off. Now you have a guide. Go slow to stay on track.
I probably would have stared at it mumbling to myself for hours. Figuring it out for YOU ? Pfffftt. Piece of cake.
Well I am sure this would work if I could find a position to saw with my right arm. The space is tight and I can't position myself to hold the saw with my right hand and my left is not coodinated enough to make a perfect cut. I guess I am looking at removing my whole filter unless there is some sought of special tool I can use.
