I turn off the water source, flush the toilet, then quickly dump a gallon of water into the bowl and siphoning action eliminates most of the water from it. Then a big sponge at the base of the tank to absorb what water is left. Two bolts and a quick disconnect of the supply line, and the toilet is easily removed. I then use a putty knife to scrape out the old wax ring residue. If you have any other questions, feel free to post away and we will help you with this job!
