Re: Bilge pump non return valve.
Just to clarify ... we only talking electric pumps here ?
Our manual emergency pump (Henderson type) has been unused for many years and I suspect that its rubber flappy thing has perished. Yes there is a seacock on the through hull.
I'm about ready to rebuild the thing but what of adding a check valve into the line as back up ? Is this OK ? Is this stupid ? Is this simply not necessary ?
