Have you checked on your boat recently.?

But then you only have one pump. What if it fails?

I was referring to two pumps that can take power from either battery, thus allowing for the fact that pumps can fail and batteries can go flat.

Then you don't need the Diodes.

With the diodes, either pump could be powered by either battery, allowing for one pump and one battery to fail. I'm not sure how to do that without the diodes.

each pump has two power sources, each pump connected to L and N from both batteries yes in the unlikely event of one battery being flat it would take charge from the other but only when the pump kicked in. This scenario is an even more unlikely event

Terry Darlington wrote ( in one of his Narrowdog books) that if you don't visit your boat every two weeks it will die.

Boats do sink because bilge pumps fail and batteries go flat. I'm not suggesting everyone does this, but for anyone who leaves their boat unattended for long periods, installing a second bilge pump and four diodes could be very worthwhile.

Surely they should be looking for a boat yard where they chek the boats daily as surely this should have been spotted

[David Mack]

 

Chances are it is, as I have an automatic bilge pump and solar panels although I appreciate other things can go wrong.

 

I once had a separate float switch connected to the bilge pump. The float switch failed in the 'on' position, and I came back to a boat with a flat battery and rather a lot of bilge water!

This is just connecting all the batteries together in parallel. Both battery banks will lose their charge together, and worse, the bilge pump wires will catch fire when the engine starter is used!

P.S. Never a truer word than in your sig!

I used to live in a house. How unlucky was that.

me too, can't imagine why.

think i'm cured now though :-}}

Yeah I know that, have to admit it was a hasty post on my part, must remember to engage brain more often!
