"The v-berth is the ONLY good
location on that boat. Any other location that has room for it is too
far from the head. Route the hose from the Traveler to the tank under
the portside hanging locker (the sole in the locker comes out by just
removing some screws)--which is also a great place to put the
macerator--and then behind the drawers. Run the vent off the tank to a
new vent fitting near the bow...don't bring it back to the existing one
behind the vanity in the head. And make the vent 1".

Do you mean that the hose gets routed through the bottom of the locker
past the v-berth drawer to the tank located in the v-berth?

Yes.

And...that
the pump would be located in the bottom of the locker with the hose?

Yes...or it can go in the v-berth if there's room.

Someone has been there befo Currently the hoses are routed directly
through the locker (in the back) to a macerator in the v-berth. The
hose from the macerator goes into the bilge and out through a
thru-hull. The macerator (Jabsco 18950) is wired shut - we don't
even know if it works.

Apparently the boat had a different toilet and a tank in the v-berth
(which is where Trojan put 'em. A PO apparently replaced the toilet with
the system you have now, and pulled out the tank. That macerator had to
have been used to dump the tank. If it hasn't been used in at least 5
years, I'd replace it.

Looks like we need to:

1. install vents

Just one new one...your existing system already has one.

2. reroute the hose from the macerator to the new tank after verifying
the Jabsco works

Not quite. I'd replace all the hoses AND the macerator and start over to
route them as I described earlier. There's no reason to have a macerator
to dump the tank, 'cuz you can't legally use it in your waters.

3. route the hose from the tank to the pumpout valve.

Does that sound right?

Close.


Lastly - why shouldn't we use the existing vent?

Because it's in the wrong location--too far from the tank--to provide
the exhange of air needed to keep the tank aerobic...which is the key
to odor elimination.

I tried emailing you to the address you post here, btw. Maybe that'll work.
