I would use a closet flange with the pipe glued into each side. The flange
will be in the center of the concrete and act as a water stop, making the
water have a longer path. Concrete only sticks to pvc when you don't want
it to. Vibrations in the plumbing, temperature changes, and other factors
will cause the pvc to become lose in the hole, but the closet flange is
thoroughly anchored.

Does concrete adhere to PVC? What is the best way to run a 4 inch piece
of
PVC through the wall of a concrete pond and keep it from leaking at the
joint? The PVC pipe will be about two feet below the water surface.

Thanks
