Can a basement floor drain be tapped into to run the drain from a nearby newly installed basement toilet into it?

If you just plan on putting the toilet on top of the floor drain the answer is no. The floor drain if it leads to a septic system or city sewer would have a trap in the line which will not work with a toilet. Depending on the size of the pipe 3" minimum you could cut the floor and tie a toilet into the line. It would also have to be properly vented. I would consult a plumber on the job. Its also possible that the floor drain just goes to a dry well which could not be used. Even if it could not be used there are other ways to install a toilet below the septic or sewer line.


Is it due to the size of the toilet or just the bad installation if the water tank of the new toilet is about 2 inches away from the wall?

Probably it is due to the size of the toilet tank. If the toilet is a low flow, or under 2 gallons per flush, the tank will be considerably smaller than an older toilet tank, which might hold as much as 25 gallons. The only critical thing in istalling a toilet is if the drain pipe lines up with the drain opening. Unless you move the toilet drain, the new toilet is going to sit in the same place. If you have a gap between the wall and the tank, you might want to put a block of wood or something to help anchor the tank. Newer tanks are smaller due to the reduced water need with the current flushing technology.


What is wrong if the sink and the bathtub will drain but the toilet wont flush?

The toilet itself is plugged or the pipe from the toilet to the drain is plugged. It may be that the tub and sink have their own drain pipe that may connect to the main away from the toilet drain. Plunge the toilet or sometimes if you fill a 5 gallon bucket with water and pour it into the toilet as fast as it will take it, that will flush out the line. It is a greater amount of water all at once an forces out what the clog is.
