The amount of time that the pump operates is determined by the amount of water that is drained into the unit. If the amount of water from the sink is less them the amount flushed then the pump will run accordingly.

Zoeller makes the best unit out there do you research first

my son put a wet wipe down the toilet, now it makes a loud grinding noise when flushed

take the pump out and haul it outside and spray it off and check in the bottom of the pump to make sure there isn't anything stuck in there. then shop vac the bottom of the tank out to make sure there isn't anything funky in there that would get clogged in the pump. sometimes the out let line gets clogged as well you can buy a drain king ( it's a rubber deal that hooks on the end of a hose and when you turn water on it swells up and sprays water out) then stick it in the outlet pipe and let her rip and see if it lets the water through.

Shut down the power and pull the pump from the unit and give it a exam. There might be something as simple as a item that was flushed down the toilet (pencil, pens, combs, etc.) or just a hair clump. Check that the float is free to track fully up and down. Good Luck!

Could be that the motor is not sitting straight, instead it cuuld be tilted and when it pumps, it vibrates and makes a loud noise. Or could be something stuck on the impeller or pump cover plate. Pry open the lid with a flat head screwdriver then remove the motor and pressure chamber, therefore you can inspect it. Good luck.

I have included the installation instructions. It also includes an expanded veiw of the toilet. The troubleshooting area can give you ideas. From what I read, it is possible that something has feel into the grill. Hopefully this helps.

Sounds like a restriction in the outlet pipe, the 2 galls from a flush are OK but the bath or shower is more, especiallly if you have flushed before you shower, try drain unblocking chemicals or flushing the outlet pipe with mains water from a hose

I think a small plastic item has dropped into my saniflo toilet it keeps maing a loud noise evey few minutes. hat should I do
