Current pvc to pool equip is 1-1/2". Pump is shot, so need to replace. Stainless (American) DE filter is in decent shape, but can not find replacement gasket, so guess it'll have to be replaced also. This is going to mean a redesign of compact pool pump area (5x7?). Will not replace 1-1/2" pipes under deck or buried, but wonder if it'd be worth resizing to 2" between equipment & valves. FWIW: Not first time with pvc - we moved all of the equipment to current site from its original location 10+ years ago. Quite a few elbows, joints & valves for cleaner, solar & "bubbles".
Resize pvc when replacing equip?

Welcome to TFP... a great resource for all your pool maintenance questions...
If you are re-plumbing with 2" because of some theoretical flow improvement, then I would vote no, as the difference is not worth the amount of work involved..
If you are re-plumbing with 2" because that will make it easier to plumb the pad using a uniform size, then I would go with the 2" plumbing.
I actually did that to a rent house pool.. All the in-ground plumbing is 1.5 inches while the pad is all 2". I could tell no difference in the operation of the system, but it made installing the new equipment (pump, SWCG, and filter) much easier.
Thanks for posting,

Thanks for welcome. Been a lurker for a while.
Thinking about resize only for flow considerations. If I stay with 1-1/2", can probably reuse some valves, etc.

2" pvc will tend to be quieter because the velocity of the water is much slower. Fast water tends to be noisy, especially if there's air in the water.

If your only doing the equipment pad it is completely pointless to go to 2", the short runs won't change the head loss, 30' of 2" versus 1 1/2, yes.
You are also adding a 2" - 1 1/2 bushing in the system which is a extra leak point, unless your equipment wants 2" then it don't matter where the bushing is.
Use unions on your pump and filter

The new pump should take 2". The new multiport should be 2". I would do everything in 2".
