@MLE_onlineI used to live in a terrace of cottages all connected to the septic tank behind my house. Our slum landlord who lived next to the terrace in a big posh house wasn't connected to that system.
Quite often the system would back up because some twat was throwing baby wipes down the toilet and our back garden would end up ankle deep in shit.
I decided to sort it myself and bought some drain rods.
Well I managed to clear it. What I didn't bet upon was a massive airlock that once dislodged caused a pressure wave to force itself back down the drain I was rodding from and cause an entire fountain of shit to come out absolutely covering me in months worth of human crap, baby wipes, tampons, towels and whatever else was stuck down there.
I was not impressed.
The landlord actually saw it from his garden too so I shouted "you fucking sort this out you cunt!" at him.
He eventually sorted it. And stole my drain rods.
