i wonder how they attach the pvc?

They don't They use 4" PVC cut to a depth equal to that of a deli cup w/ a 4" diameter. The deli cup then sits down in the PVC. Think of the PVC as a sleeve. I like the Dollar Tree 6" dog bowls, but our local stores haven't had any for a couple months.

The other thing about the deli cups.... disposable vs. must be sanatized !
