Toilet doesn't flush strongly enough and i'm sure lots of other people are going through or went through the same problem. Here is a simple solution for it; no need to call the plumber.
Your fill valve may not be set to the right level: Check the manufacturer's instructions to set the fill valve to make sure the water level in the tank is correct. For instance, most Kohler tanks have a proper fill line marked inside the tank. And a good rule of thumb, if there is no line, is to keep the water level a half-inch below the top of the overflow tube inside the tank. Some of you will read this and will still not understand what it means; just try it, open up your toilet and it is very very easy.
