Is there a way to check through the floor of a house where the element that obstructs the flushing of the toilet flush is? (maybe 1 little child toy !!!). But this may also be from a pipe bend !!!
If your system has always worked well until then it is not a problem of structure but a problem of shutter. You can rent a pipeline inspection camera that allows you to determine the exact location and may also be the nature of the plug of your pipeline. Consult the FAVREAU-LOCATION website for more details on the rental of this type of equipment. Then it will be necessary to use a rotating or pressure ferret.
