Bilge pump question

We've finally moved up to a larger and slightly more complex boat, so expect to start seeing many more questions about things as I learn/dig into the boat.

My question is; this boat has a manual bellows type bilge pump located in the cockpit, (the kind where you open the access port, stick a handle in and pump.) with the intake hose located in the lowest part of the bilge. And where this seems to get funky is that it seems that the PO plugged a tsunami 1200 into the intake end of it. When I run the electric pump, the manual pump seems to act like its on the down stroke and pop the access port open. And when I pump the handle with out help of the electric, It really looks like the water is being sucked into the bottom of the tsunami electric pump.

To me this doesn't seem like a very efficient way to work, for either system. I haven't been able to completely trace all the hoses all the way back yet, and will do so to confirm my suspicion but, going on the assumption I am correct. I'm not wrong in thinking this isn't an acceptable set up?

Thanks for any input.

Re: Bilge pump question

What you are describing is a pretty common, but obviously wrong installation. One of the pumps needs to be moved to a seperate line.

Re: Bilge pump question

Greg,

Thanks for the input, well if its common that's better than just being completely screwed up.

It did seem to work for both pumps, but I know my little 500gph whale just about shot water out of my smaller boat, of course this larger boat has larger hose and a longer run but I did expect a bit more flow out of a 1200gph, and assumed having it pump through a gusher pump was slowing it all down.

Extra hose, and a separate run is on the to do list.
