Automatic bilge pump

ffactj

I have a switched bilge pump, which is kind of old and i dont trust it.
I want to replace it with an automatic bilge pump with an integrated automatic switch.

Can anyone recommend a pump and an automatic switch.
Ive seen a few on Amazon but not sure which to go for.

Maybe something like this

http://www.amazon.co.uk/750GPH-Automatic-Submersible-Electric-separate/dp/B00MQN0LIK/ref=sr_1_19?ie=UTF8&qid=1414424577&sr=8-19&keywords=float+switch

along with this

Or am i going about this the wrong way.

Thanks.

Rule pumps would be the most common here and the setup would be something like this you could also add a warning light on the dash if you wanted. The switch and pump you posted will work fine depending on the size of your boat I always like to go for more GPH than I need just to be on the safe side

Brilliant.
Thanks for the diagram.
Thanks for that. Boats only a 16ft one, so hopefully it should be big enough.
Was thinking if im leaving it in a marina it needs an automatic pump and then looking at the pump in it i wouldnt trust it anyway.
