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!

Thanks -
