I've failed at home toilet repairs. Fortunately it's all stuff in the tank that's wrong so I've disconnected the water to prevent it from doing any more damage and I've got a bucket that I can use for flushing until I get a plumber out to take care of it. Why do people install toilets so close to corners such that there's no way to see what you're doing and can't get a wrench in the space? Maybe I'll give it one more try.
