Grinder Pump Install for Basement Bathroom elect Q..


Hi all: Planning a basement bathroom install and I've been reading up on grinder waste pumps for pumping up the sewage waste to the main stack. They all seem to be 115vac plug in. Not hard wired. So my questions are first, how do I run the cord from the pump to an outlet? I want this to be concealed and not some ugly cord up the wall... Second, would it be better to plug it into a GFCI recept. or a same breaker? Third, does the pump need a dedicated circuit or can it share the 20A circuit for the bathroom? Fourth q is would it be overkill to install a 20A GFCI breaker on the circuit for the bathroom and GFCI outlets throughout?
Thanks!!!

You run a new dedicated non GFI 20 amp. line to the pump.
A bathroom can not share outlets with any other room.

The grinder pump might not be in the bathroom. I don't think it needs a dedicated receptacle but I think I would probably put it on one.
The cord could follow the pipe to the receptacle. The cord should not be hidden inside a wall.

Most, if not all sewage basins come with gas tight lids. Within this lid is a gas tight grommet to feed the pump and/or float cords through.

Also consider an alarm float as well

my following question has nothing to do with the original question. Are you on a sewer system or a septic system (tank, leach field, etc.) I ask because a girder pump will cause damage to a septic system as solids would be ground up and enter the leach field where the aerobic bacteria will not digest the ground up solids.

if on a septic system you would need a effluent pump that is capable of pumping solids.

Just thought I should ask ....

Good luck!
