Hi Joel,
That's not a bad idea if you can fit a float type cockpit drain in
the heads basin drain. This is from a UK supply but you get the idea.
http://www.force4.co.uk/4585/Force-4-Cockpit-Non-Return-Drain.html
Two details of importance:
- the bilge pump goes to the large port of the Groco manifold as the
(large) primary user, the heads basin then has to go to a smaller
port and should have a screen at the basin to minimize fouling at the
manifold (shavings & other hair are very real plugging concerns with
an elbow transition to outlet.
- the bilge pump will REQUIRE a vented discharge loop to prevent
siphon when idle and the internal check valve leaks-by.
Another idea:
My toilet intake passes under the heads basin. So I teed the basin
drain into the toilet raw water supply. It works like a charm, basin
drains out the intake trough-hull and when the toilet gets used there
is good agitation to clear the basin drain.
As an added bonus, being a salt water high organics boat area, before
I leave the boat for any length of time I close toilet supply
through-hull, half fill the basin with fresh water and pump through
the toilet. When I get back and use the boat there is no sulphur
smell in initial uses of toilet, sweet :)

Andrew,
Good point. The current manifolds mix intake and discharge. I've
never tried using the head with the Y Valve set to discharge, but it
could be ugly!

I like the idea of cutting down the number of holes in the bottom,
but I think through hull manifolds are better used for intakes. You
would certainly need a check valve in each drain line if you had
them sharing a thru-hull.

All,
I am having thru hulls replaced and reconfigured. I'm considering
running two lines (Heads sink drain and emergency manual bilge pump
in the cabin) into a single thru hull and using a Groco manifold such as this:

I'm trying to minimize the number of holes in the bottom.
Thoughts? Recommendations?
