Ok so don't laugh, but I'm pretty pleased with myself this morning after fixing the toilet all by myself last night!
It's my first venture into DIY plumbing, so after couple of videos on youtube, and a quick trip to the hardware I managed to replace the mechanism inside the tank and to the total surprise of my wife, it all works :)
$13 all in all, would have probably cost about four times that to get someone in.
Youtube is my favourite learning reseource. Last weekend I also managed to replace my cars cabin air filter, so now the car smells far better too.
Edit, sorry I see there is a DIY section. Mods feel free to move this thread if needed.
