I've got a problem that I think has only started occurring in the last week or so, my toilet seems to keep draining for up to hours after it was last flushed, and weirdly so it seems to be affecting the en-suite upstairs as well.
I'll start by adding I know little to nothing about plumbing/toilets
The downstairs one (that was flushed most recent) has the water level just about inline with (i think) the overflow valve, and it's just currently constantly draining at a slow steady rate. Image
At the meantime the upstairs one is seemingly very low level in the tank, but just isn't filling up, even if I manually try adding more, this one is also draining, just very very slowly. Image
Is there a simple fix? Do I just need to put more water in the whole system, or is there something I'd possibly need to get a plumber in for?
I've watched a few youtube videos, mostly about replacing the cistern for a new one (which I've just bought, doesn't solve the problem) although I think the issue specifically seems to be that the water is just going in the overflow, there doesn't seem to be a problem with the valve at the bottom, when I flush it, it does stop for a little bit until the water hits the overflow valve and then just keeps going, it's as though it's never told to stop filling the tank back up
