My lovely son has done the biggest poo known to man this morning in our only toilet.🙈🙈🙈It has flushed but is stuck in the waste pipe. I’ve done everything suggested online put washing up liquid down poured a bucket of water down and bicarb and distilled vinegar and plunged with the toilet brush. But the water is still coming up quite high when flushed. I am trying to clear it before anyone else needs to use it. He has autism and is totally unaware of the drama he’s caused. Any suggestions of anything else I could try please? And Happy New Year.
