Hi y`all
I have here a Gulper 220 and have been thinking on using it as a single main bilge pump whcih will be run from three float switch`s that are T`d off to the main pipe run. One being under the rear deck and the other two in the cabin.
Question is will this work or will it draw more air than water when one float switch engages? Or will fitting a non return valve help in all three lines to the pump.

Yes air is much easier to pump than water, so you will just pump air, You would have to have some sort of float valve that only opened when there was water to be pumped, otherwise it would be closed. I'm not sure that such a thing exists. No point in fitting non-return valves, that won't help at all.
It will be much easier to have 3 pumps, or manual selection of which bit you want to pump from using valves.

As nick says really.
Can you not arrange for each section to be joined and run to one area in the stern?
My mates Buckingham is free to run from bow to stern where he has a little whale submersible pump laid on its side - like you would use in a water can, they are cheap as chips.
Would leave the gulper free for the shower then.

I cant use the gulper for the shower ( ah unless as I think I remember you saying to have it run on a switch and the Shurflow for the sinks ? ) as it is not a smooth runner like the Shurflow or run on a pressure switch. |

Yes, that's the easiest way, have your shower and flick it on to drain when finished. Sumps can incorporate float switches but you loose a lot of headroom. |

If i can sort parts for the Shurflow i can use that to run the system. The Gulper to MT the shower  and i was thinking on piping it into the water sytem to pump/drain it when needed as it is a big pump and will MT it quick. |
