My toilet won’t flush

A common tank type residential toilet will not flush unless the tank is full of water. Check the tank, if it is not filling there may be a problem with the valve, the plug, or you may not have water pressure in the line feed the toilet.
A commercial toilet will not flush if it is clogged, or if there is no water pressure in the lines feeding the toilet.

First of all, have you waited long enough for the hot water to make it to the faucet from the heater. This can take several minutes depending on the distance.
