We just moved to a new house. One of the toilets is a Toto - I'm not sure which model. I've attached a picture of the number on the inside back of the tank (8536: 410), but it doesn't seem to correlate to any Toto model I could identify. Similarly the fill valve has the numbers 30 0505/10. While everything seems to work OK, there is no hose from the fill valve to the overflow tube, nor does any water come out from the place where a hose would normally be attached to the fill valve. Should I change out the fill valve? I have an extra Toto Universal Fill Valve but it doesn't list either the tank number or the fill valve number in its list of compatible models.
