Bilge pump outlet backflow

Just started getting backflow into the bilge from the electric bilgepump. Flushed the hose, no blockage, new pump, no improvement. Another sailor suggested the checkvalve in the outlet hose may need replacing. Does anyone know where this may be located, and how to access ?


Hi Bruce,


There are a couple indicated on the grey water layout diagram in the resource section of the website.

Thanks, I did see that but didn't correspond to where the hoses lead on our boat. Must have been switched around at some point. Think it will be a job for the boat yard experts at next lift
