It's been now some weeks that my wc is behaving strange, leaking water when refilling. I found the time today to open it and I noticed that, after discharging, the refill mechanism seems to work fine but the water does not come out from where I expect it. I'll add some pics and explain.
on the left there is the valve, a fluidmaster 747 (pretty cheap standard piece it seems). Basically, when it refills water drips out from the top part, not where a hose is supposed to be attached (missing here, who know why, it has not fallen inside) but from the back, in a jet that sometimes is able to drip outside of the cover and makes the area below permanently wet. Sorry for gif quality but weight limit on images gave me trouble.
I'm not sure if this is the normal operation and it is just oriented wrong or what else happened here, how can I fix it so that water does not drip outside? It is cheap, but I would like to avoid replacement, also just so you know, I'm a tenant if it is relevant for any advice.
