410 Express no fresh water with leak center compartment

[DGAM]

With fresh water hose connected from shore all water systems work fine.

When using holding tank water (full) i get no pressure , no water service anywhere and leak in center compartment 45 angle top left corner dripping appears to be coming from head sink shower direction

leak is forward of sump box coming from top left corner of compartment looks like from bath area

weird that there is no water pressure anywhere

sometime the pump works others it doesn't with facets open

what is robbing all the pressure and stopping the fresh water pump intermittently?

so far can't seem to find the leak strange that non of the fresh water facets work ( aft , kitchen,

any ideas
