Correct, it's a float for the sewer flap. There are quite a few of these around but this is quite an old one.Panic! wrote: ↑02 Feb 2018, 8:25 pmI've never seen one of those before. But I suspect you're right about it being some sort of sewer relif valve. There appears to be a cylinder above it, and a trap door in the far wall. It would be great if you could stick your camera down there and get a shot looking upwards and further in.
I suspect the weight normally holds an overflow door closed and the cylinder is a float that opens the door. Or it could be a flood gauge. The cylinder flips a switch that somewhere indicates the drain is flooding.
All speculation of course. Which drain is it in? Or Which suburb is the drain in? Please don't advise the exact location.
LOL. Yeah, I remember that ones. I also remember hunting along there for drains with Id back in the day and popping manholes only to find they were sewers. Yuck.
Yup from memory there was a disk in the roof of the alcove which connected to it all and looked like it would move if i lifted the weight, very quickly decided I didn't want to be involved with that at all.Panic! wrote: ↑02 Feb 2018, 8:25 pmI've never seen one of those before.

I didn't poke my head in this one, but I did on one of the cleaner ones further up and you could get a good look of the system in there, that's when i got a bit of smell but it just didn't seem strong enough to be crap but hey I suppose that's a good thing.iso wrote: ↑05 Feb 2018, 3:52 pmCorrect, it's a float for the sewer flap.

As for lack of smell, pop the hatch and catch a whiff
There's the chance it hasn't operated in a very long time, so no guarantee you'll get any stench...
The one at the outfall of Dwellers' Tomb is probably the most active I've encountered... yuck.
