Check manufacturer specs…everything looks fine. Should be able to handle water loads but it varies. Yes they have backflows or I think they’re called return valves in a self contained macerator unit like that. I would never plug a poop pump into a GFCI outlet.
The manufacturer will more than likely state that it should be plugged into a GFCI outlet.
Personally, I wouldn’t do it nor would I plug a sump pump, refrigerator, freezer, etc. into a GFCI just because it’s a mechanical device and mechanical devices can fail.
Just a plain ole’ dedicated outlet for me;-)
I 100% agree with Joshua. I don’t know why they didn’t go with a grinder pump in a pit over that little macerator pump? with a toilet, sink and washing machine on it. I trust the professionals know what they’re doing.
I was curious to the reason why JLF thought a GFCI was not needed.
Any outlet withing 6 feet of water should be GFCI. I drill that into my clients all the time.
As far as a failing GFCI, I’m sure it happens but that is a thing I DO NOT drill into my clients.
They are nervous enough
