The supply line is blocked, tank is too high, etc
That is a fill valve and is part of the ballcock system. When someone pulls the lever, that pulls the chain and lifts the flush valve flapper and empties the tank into the bowl. That causes the float to drop, opening the fill valve and allowing water from the supply to enter and refill the tank.
Because water flows downwards, and by help of which we can get a evenly distributed water supply in the house.
The water is fed to the house by gravity, so a pump is not required.
Yes, if your house has a septic tank water from the sink and bath will eventually goes to the septic tank. However if your house is equipped with a fully dual grey water/black water sewage system, water from the sink and bath will first go to the grey water storage tank, the toilet will fill its tank from the grey water storage tank then flush through the black water pipes to the septic tank.
I believe that you fill it with coolant, as the tank's name suggests.
If it is a small amount of water add a can of Heet to the tank and fill it with gasoline. If it has allot of water you will need to pump all fuel out of the tank, add a can of Heet and fill the tank.
No, a hot water tank heats water by itself.
Bad fuel fill.
== == Two possible problems............... The main shut off valve in the house is closed from the in-coming city water supply line, or the city supply line is shut off at the street .
If it is just the toilet that doesn't have water, then the pipes are probably not frozen. If it is the whole house than maybe yes. If you have water at other faucets, look at the toilet and see where the blockage is. Disconnect the supply line under the tank and see if water is coming through the shut off at the toilet if there is one.

Shut the water supply to it and drain it.
