I just installed 2 toto aquia the CST416M model, one of them is working perfect but the second one the water keep running inside the bowl from the four rim-holes in the back of the bowl, the water comes down slowly but it's annoying. so i called toto usa they aske me to check and clean the flush valve seal, so i did but nothing changed, then i switched the flush valve from the other toilet that is working good but no luck the water kept leaking inside the bowl.
and i can't figure out why the water is leaking only from the four rim-holes in the back. so any suggestion would be appreciated thanks.
