Replacing Flexible Tubing with PVC for Above Ground Pool

I have been helping my new neighbor with his pool. He has no previous experience, so I felt bad. One thing that I noticed is that he has a bunch of flexible lines, and they all seem to be leaking. I thought it might be nice to help him convert to PVC. I don’t have much experience with above ground pools, but I assume the pipe connections are similar to inground. At the very least, I would like to replace the line from the pump outlet to the filter inlet. The pump connection seems to be on an angle (not straight). The pump is a Pentair Optiflo OPT-NI-1VD, and the filter is a Hayward E-series.

My thought is that I should use a union at the pump and possibly the filter too, but I wanted to see if could get some guidance for the parts that I would need and if they’re all available at Lowe’s/Home Depot or Amazon. I have 1.5” PVC, teflon tape, thread sealant, a pipe cutter, wrenches, etc. I’m not 100% clear on the fittings and what is needed for the pump outlet, so any suggestions there would be greatly appreciated.

Also, are there any good tips for leveling the equipment? I noticed that the filter is leaning forward and the pump is also leaning. They are just placed on some pavers/blocks, and the pump is not even secured in any way.

The hard part to source is usually the fitting at The pump. They are easy to find at online pool suppliers, but not so much at big box stores.

One thing that isn’t obvious when installing rigid plumbing on an above ground pool is to avoid creating a ladder with the plumbing that would allow a child to climb to get in the pool.

I just replaced some of my stuff w/ a mix of pvc & flex pvc. I used flex pvc from the pump to filter w/ a 45degree elbow & a union. Don’t forget to add valves as well. I have one at each return & one under the skimmer so i can open the pump basket without a deluge. I wish i had put one between the pump & filter too as water still comes out when cleaning the pump basket just not as bad as before i had the skimmer valve. The one under my skimmer has a union on one side. Those are nice if u can find one.
When I upgrade my swg i will change out the rest to pvc. E1233BE0-EA60-402F-8101-3B496052ECAC.jpeg
