Backup bilge pump: plumbing and wiring - 04-25-2008, 11:57 AM

My secondary is on a separate switch I put under the
dash so it is not automatic, but for the output,
rather than make a second hole in the body I went to
the hardware store and bought a 3/4" tee fitting and
also a brass check valve that has 3/4" fitting. This
allows routing both sets of hoses to the original
outlet in the body. The check valve is vital. It
allows water to go only 1 way- out. Without it, unless
both pumps are operating, the water would run right
back into the bilge by way of the second bilge pump
hose.

So it seems like a second bilge pump is a good idea.
Any tips on the best way to plumb and wire it in?

I was thinking about using a submersible with a float
and wiring it straight to the battery so it's always
hot. Or maybe use a 2nd battery which is isolated?
What have others done?

And then where do you run the hose for the output of
the 2nd pump?
