Hi all,
I'm plumbing in a new washer and laundry sink and pump in the basement. I'll be tying into the existing ABS waste line. I'd appreciate any input here on a couple of questions:

Any benefit to sticking with all ABS from the new pump to the existing waste line? I'm not a fan of the rubber sleeve check valves I'll need to install above the pump discharge. I wish they would start making the solvent weld with union check valves in ABS instead of only PVC.

If I install new PVC from pump to existing waste line, I could use my preferred check valve but then I'd have to tie PVC into ABS. I've solved this in the past by tying in an ABS MIPT adapter and then connecting a PVC female threaded adapter to it.

Maybe either choice is good? It might be kind of dumb Im getting hung up on my choice of check valve.
Hey, wait a minute.

This is awkward, but...
