I have a downstairs bathroom connected to a tank with a pump to move sewage up & out to our septic system. When the toilet is flushed, the water drains slowly, the bowl almost fills completely and the sink & toilet both start to gurgle & bubble. The drain line from the washing machine sink is connected to the vent so I disconnected the drain at the vent, as I thought maybe it was a venting problem. I also eeled down into the tank. This didn't make any difference even with the connection left open.
I then opened the clean-out at the sewage pipe where it goes through the basement wall, thinking that maybe there was some blockage - everything was fine.
Could there be a problem with the toilet drain to the tank? Would the sink line be connected to the toilet line? My next thought is to remove the toilet & see if I can eel a problem out of this line -- I'm hoping for some help as the last time I did this I cracked the bowl & had to buy a new toilet.
Also, all the upstairs drains are working normally - so I figure it must have something to do with the tank/pump/toilet in the basement.
Thanks for any help.

I'd bet the farm that when you checked the lavatory vent you would find it clogged. Check it and tell me if I'm right. Regards, Tom

Turned out to be some blockage from the line to the tank in the basement and debris on the pump float that stopped the toilet from flushing properly. (Meanwhile I removed the toilet & didn't break it - but when eeling the drain line from the basement shower, the line disconnected from the tank & had to get a plumber in to open the tank & re-connect. Thankfully I didn't need to break the concrete to get at the pipe.)

I have the same problem and have already checked the vent and the float has been adjusted.
Could the blender/macerator be too small? What next
