I bought on in 2008 to use at Sister place....pumping 75' with a 2' rise
I ran 12VDC to dump line area and just plug it in
3/4" garden hoses
50 gals black...roughly 10 minutes then I shut it down for 5 minutes then pump 70 gals of grey for another 10 minutes then flush while running with clean water
Have used it over the years at numerous places....but Sisters is the longest distance
Once a year I disassembly the head and clean impeller and chopper plate ...usually hair
Impeller is nitrile (synthetic rubber)
Chopper plate metal
Haven't had any real issues in the 12 yrs I have owned/used it
