We have an old Sealand 911-M28 and are going to "upgrade" it to the
711-M28. Through reading this group, I understand that one can
install an inline pump to a secondary (larger) holding tank and have
the pumpout rerouted to the secondary tank. Does anyone know how I
can get more information on doing this?

We have a 1988 Trojan F32 that my husband and I use it for cruising
the Chesapeake and are tired of pumping out every 3 days. Also, the
solution needs to be an economical one. The secondary holding tank
in the V-berth seems perfect. Any feedback from those who have done
this would be welcome!

If you're going to put in a new tank, why not install a big enough one
and remove the old one? KISS.

You'll eliminate many possible sources of leaks & smell, as well.

Get Peggie Hall's book on Marine Sanitation, which I've seen in at
least West Marine and Fawcett's around the Bay.
