RE: Holding tank and water tank=which side for pump out and fill???

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. If not than I should replump and get the hose from the macerator to the discharge seacock with a loop in it higher than the water line as an additional safety factor to a closed seacock.

Here on the Gulf Coast we have to be 9 miles out to discharge.

The other manual pump is a bilge pump.

Thanks for the schematics. I'll have to figure mine out one of these days. 78 degrees today--kind of hot down in the bilge of the old boat, but tomorrow it will be cooler.
