>>2928671It's a bit of a shitshow right now, I have another toilet that's much more respectable so this one has been neglected.
Problems started when water started to come up over the relief valve and I would have to try to bend the arm of the floating device to adjust it, though it was tricky to get it right and not end up with it too low. There was no other way to adjust it. A few days ago with too much force applied to the valve it simply came apart.
The screwdriver is holding up the arm of the float device as it's the only way I could get it to shut off. There is no isolation valve anywhere - I tried to see if I could twist that indent you see with a screwdriver and could maybe shut it off that way but it's not possible. And yes it has to be that high and in that position despite how the floating device never went remotely that high. It actually took about 20 minutes for me to get it in that position to stop the valve. There is no way to turn off the valve otherwise except to go out in the road and turn it off there which turns off the water for not only the whole house but the farm also - old houses man. I've purchased isolation valves though I really don't know where they would go.
That nut there - should that go clockwise from this perspective side open it and take it off? That's how the analogous nut on my new device would go. Maybe I could try to hold the nut at the other end in place with my fingers while I unscrew this one. I genuinely have no idea how you would ever get to the other nuts, it's in a hole in a wooden panel, with a drainpipe and other pipes and electrical wire around. It's like they put it in first and then did everything else on top of it - drainpipe, other plumbing, electrical wires - all built on top of it and now no proper access to it.
