In my case water is flowing backwards thru the underwater seacock, than thru the non-working macerator pump into the holding tank. Will a properly working macerator preclude the backward water flow.

*Are you saying*with the sea cock closed the water is still getting into the holding tank?
If it isn't then what is the problem, close the sea cock and be done.* A new macerator will do the same thing, flow back into the tank, most do not have a check valve.* The vent loop will fix it but why bother.*Why do you need the sea cock open?
