Rv waste pipe

I have a 2015 Catalina and recenlty replaced the 1.5" grey water valve. The Flange holes where the bolts pass through boke on the top two and now the valve leaks. I believe I need to replace the WYE 3"- 1.5" 3" Bayonet discharge... and repipe a portion of the grey water piping.

Is the pipe standard household 1.5" PVC dimensions? Can I just buy the ABS pipe and elbows at my lowes in town or do I need to buy that somewhere else?

Thanks in advance...

I replaced my sewer outlet with one that had a Y coming into it because I added a new drain for my washer/dryer.

Standard 1 1/2” is fine. PVC is quite heavier than ABS.
