i started smelling the sewer again this morning, and i started freaking out. it might have been paranoid, but i took action - and noticed that the drain had indeed drained almost entirely, very quickly.
it's probably draining out through something upstairs that needs to be flushed. i guess that's what's happens when he leaves for days at a time...
as more data is collected, i understand it better.
as it is, i've decided that i'm not fucking around with this anymore. i'm not waiting to react. we've now got a schedule.
every 12 hours i will dump 30 litres of pure water down the hole. that's about what it took to fill it up this time. i'll then add another 5 or so litres of dish soapy water.
this will happen until we get a plumber down here...
the liberals are supposed to do better than this
