Some proper horror stories on this thread. OP – that does sound nasty, but nothing beats unclagging drains.
Our toilet started backing up (rented house, years ago) and the back yard began filling with sewage. Phoned the landlord and his wife told me to come round and borrow their telescopic unclagging rod thing.
I lifted a manhole cover in the back yard and was faced with a two metre deep pool of raw sewage. I was instantly and wretchedly sick, which only made things worse, as I now had to kneel in the pool of sick to get near the pool of shite.
Half an hour of ramming this pole up the drain running toward the house passed before it dawned on me that the blockage might be in the drain running away from the house. By this time I had nothing left to puke (it was a very hot Summers’ day). My method was; run out into the back lane, take a deep breath, run back in and shove the pole in, run out of air, take a deep breath, retch bile into the very pool I sought to diminish, repeat ad nauseum (literally).
Finally, the reason behind the blockage became clear – it seems it’s common practice round these parts to place a roof tile over the entrance to the main sewer system to stop rats jumping out of your toilet. The tile had slipped and completely blocked the outflow.
Took weeks for the stench to clear and my mind has never been right since.
