Blocked soil pipe after installing replacement toilet

[Deleted member 120897]

Does it make sense though that when this is off completely and top of pipe open, that it flushes perfectly?

Yes, I’ve had this myself on jobs I’ve attended and it’s always been a blockage/partial blockage.

Yep blockage if you flush enough it will start to back up

Sorry for the late post on this but just wanted to say thanks for your help. It was a problem underground. Had a blockage underground and once fixed, everything worked perfectly. Thanks for all the help!
