Pentair Whisperflo Bearings Starting To Sing

Thanks, Pool Clown. It's intermittent, but she's singing more and more. I ordered an identical replacement for an outstanding price from a reputable online retailer, and picked up some new Southwire conduit and fittings today. I'll probably switch it out as soon as I find the time - which may be before it fails - because my schedule is pretty hectic right now. Do you foresee any problems using the existing unions for a couple of months, and then installing the new unions later, probably at closing? Thanks as always, I appreciate your advice.

One last question: the pump is actually a 1.5HP Pentair SuperFlo - I mistakenly described it as a WhisperFlo). Just ordered the identical pump as a replacement, I'm wondering if I should change order to a 1HP?

~17,500 Gallon inground

Plumbing is all 1.5"

Equipment pad is roughly 20' from pool and at same elevation

2 intakes (1 skimmer + main drains)

7 returns (3 on side, 2 in step section + 2 laminar jets that I use only occasionally, but when I do I like them to fly high)

Pentair Sand Dollar SD80 (3.5 sq ft filtering area, 50PSI max (consistently reads 20PSI w/ existing 1.5HP pump), 75GPM max flow rate

Pump flow rates are ~90 for 1HP, ~100 for 1.5HP.

As always, I'm very thankful your advice.
