2002 400 sedan bridge - location of duckbills

[leh3324]

We have a clog. Pretty sure that something went down thru the master head. Read the posts about how to change the duckbills but how the heck do you get to them? It looks like I can only see the system from the floor opening outside the master stateroom. If this is the only access, we will have to remove the gray water pump system. Can't see any way thru the engine room. Help??

The sealand pump on my '00 400DB was just aft of the holding tank (port side) but it was not a factory installation so location could be different on yours.

I believe there are access panels in the port stateroom under the inside bed. If you open that area up there are several panels that can be removed. Also, at least on my boat, I can gain "some" access by removing the stairs (salon a/c unit area). That should get you to the pump and the duckbills, at least if it is the same set up I have.
