Bob,

ok...now I'm learning something. I always thought that 'schedule' referred to a combination of O.D. and I.D. but apparently, after a little research, that's not right (1.5" schedule 40 and schedule 80 pipe are both the same O.D., but different I.D.). As you point out, schedule is simply a wall thickness that affords a particular pressure rating -which I don't need.

The issue I have is that right now, I have the pipe and all the fittings (except the Tee) in white and all schedule 40. I'd be happy enough to switch all that to a grey PVC of whatever schedule (or none) as long as I can get all the bits for that to match up (and fit). I have no idea where to get the other pieces in grey !

I wasn't going to glue any of this in case I ever need to take it apart (and since there's no pressure to speak of, I didn't see a need).

If you have a chance to look and see if you have the white pieces, I think that would be my simplest solution. Otherwise, I'm open to suggestions.

Thanks for the help.
