Water won't flush down toilet but flows down drain fine

[jmiller5580]

Water will not go down the toilet, just fills back up the bowl. We have taken the toilet off and snaked but came back with nothing. Poured about 10gallons of water from a bucket down the drain in the floor and it flows fine, never coming back up. We even bought a new toilet and put it there and it does the same thing. We snaked the toilet as well and no clogs either. We tried forcing water through the toilet thinking it may be airlocked and water can be forced down it but still when it is flushed in either toilet it fills the bowl instead of going down on its own. Is it possible for the pipe itself in the floor going to the septic to be airlocked? If so how do we burp the system to fix it? Please help! Have been without a functioning toilet now for 6 days in the house...

Have you opened up the septic tank to have a look? My guess is the field is saturated or clogged and the tank is full.

We did dig up the septic tanks last night and there is no water coming out through the end of the pipe going into the tank, it appears that it is backing up into our bathtub grease trap which is why it appeared to go down the pipe fine through the bathroom floor. We believe the slope on pur pipe is not enough and it is flowing so slow that build up is getting in the pipe after so long because we have had this happen before. We are going to try to rot-rooter the pipe tonight and see if we can get the build up out and then consider the thought of having to replace that pipe and redo the slope so that it is correct, hopefully without having to replace the whole system if possible.
