2400 SD Maxum

[Maxum2005$]

How do I turn on pump for rear and front shower heads.

I don’t know this model but if it has a cabin there should be a red rocker switch for the pump. If no cabin I would think there would be a switch at the helm or near battery panel.

By Fridge possibly.

On my 2004 2400SD instrument panel, it's the last switch to the right...between the nav/anchor light switch and the 12 volt outlet...and it's labeled 'water'.
