I thought I had this problem solved.....

New Sherwood pump with one piece bronze casting

Global run-dry impeller...

But no.

The global impeller has started to shred itself and we had code 7 after 173 hours.

Admittedly that's nearly twice what we were getting from the Onan pump and impeller, but its still not very good !

Cheers
