RE: [Paddlewise] Electric Bilge Pump Question

I bought a Rule 1100 pump.  1100 gph nominal flow, 3.3 amp draw.  I plan on
using either a 4 AH gel cell battery that I already have for a depth finder
power source or purchasing a 2 AH gell cell battery for dedicated service.
I also bought a marine grade switch, waterproof fuse holder. When I
discovered the potential problem with the lack of a check valve, I
considered putting the hose in with a couple of bends to form a trap.  I
may still do that.  What are you using for a battery?

Thanks for the prompt reply.

I fitted an electric pump without a one-way valve to my Capella a couple of
months ago, and I have had no problems - not a drop of water in the cockpit
via the pump even rolling/surf. The outlet pipe from my pump isn't as big
as
1 1/8 inch, and I fitted the outlet port to the side of the hull at the
back
of the cockpit, just under the deck line with the outlet pipe running up
the
inside of the hull to the mid point under the peak of the rear deck and
then
down to the keel line, then up to the pump body. Inevitably the outlet port
gets washed by waves almost continuously, but I think that any water which
splashes in just runs  back out again, and the small amount that doesn't
just sits in the pipe without reaching the pump.

I would avoid mounting the outlet anywhere on the deck - water will be much
more likely to run in .... and depending on the wind .... when you switch
on
your pump you will get a shower!

What type of pump did you go for ?
