Ok that clears up a couple of things. I thought it looked like an ABS fitting.
Did you just glue the elbow flat to the underside of the top of the box and then glue the tube to the other side of the top, or does the tube pass right through the box top and is glued into the elbow.
Hope that made sense.
Action shots would be great. I'm like Troy, I like to watch.
ops:
Thanks.
