Does anyone know how to access the shower sump pumps in both the forward and aft bathrooms in a 1980 410 Commander?  Neither of them are currently working and are in need of replacing.

Hi Brandon,

Good morning from the Lake of the Ozarks.  Just another day in Paradise and waiting for warm weather...  The aft sump for your 410 is midline in the aft end of the engine room.  Small panel you lift out.  Here you will find the shower sump and two bildge pumps.  The forward is in the v-berth.  Pull up the carpet and you will have an access panel in the deck.  Pull it up and you will have the shower sump and a bildge pump.  If you email me at I will send you the plumbing diagrams for your 410.  Have a great day.

Here is the plumbing diagram


Hey Charlene

Do you have one of those diagrams for a 42' Commander.

Hi Trey!

Unfortunately we don't have one for a 42 Commander.  As members share what they have we have included them in the Resource Collection Vol. 1 and now the Files section.  I checked RC Vol. 1 and we don't one.  Maybe a member has something that they would be willing to share.
