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.

Won't work, because the SeaLand 711-M28 Marine Traveler is a
self-contained system...the toilet is mounted on top of the tank.

I can't argue with THAT advice, though.

Can you put a tee in instead of rerouting?

You could...but it wouldn't make much sense. 'Cuz you'd have to
complicate the plumbing by also routing the discharge fitting from the
larger tank to another tee or y-valve or install a second pumpout
fitting for it. Much simpler to just move the waste from the first tank
into the second tank--as you would from a toilet--and only plumb it to
the existing deck pumpout fitting.
