4000 express fresh water pump

My new to me has two fresh water pumps. Did it come from factory that way.  Has two circuit breakers on the breaker panel. The pumps are not same. Appreciate help. Jack

As far as I know the 2 pumps are there to minimize water pulsing when more than one faucet is being used.. each have a different capacity. This has been a subject of several posts on the forum.. I use both when using the internal water tank....M2C

The next time you are at your boat could you send me a pic of your pump set up. Previous owner sort of messed it up. Thanks. Jack

Thanks for pic..I still don’t under stand where the pipes are comping from and going to.  Attached is my pump layout and it is noisy as hell.

Thank you. Mine looks like a rats nest. Don’t know how to thank you.  Jack

I have been wondering the same thing. Mine is a bit different. Both are fed from the freshwater tank and both will feed all the taps. The biggest difference is the pump sizes on mine. The larger of the 2 pumps is actually connected to an accumulator tank. The smaller 2nd pump never kicks on unless the "main pump" is switched off. I chocked it up to the smaller second pump as being a back up.

What’s wrong with tearing both pumps out and putting in a large surge tank and A strong fresh water pump. Simple is good. Jack
