Will the taped end will not leak with 80 PSI air in the conduit?

Well, if it does leak, the sand above the duct tape will dribble down
into the 3/4" conduit creating a rather awkward clean up exercise.
That's why conduit runs usually terminate above the ground, not below.
The trick is to find the conduit end without blowing off the seal.

Hi Jeff

It may be of little interest to the OP, but the sand might have difficulty
leaking back into a conduit with air blowing out of it. In addition, the
air might leak from a small rupture below the oipen end of the conduit.
The OP may have no access to compressed air anyway.
