Toilets account for up to 30 percent of an entire household’s water usage. In the average American home, the toilet is the single largest user of water on a daily basis. One of the easiest and most effective ways to reduce water waste in your home is to replace your older toilet bowl with a newer, more efficient model, as older toilets can use over three gallons of water per flush.
How to Remove a Toilet Bowl - Turn the valve clockwise to shut off the water supply to the tank.Remove the lid to the water holding tank and flush the toilet as many times as necessary to remove as much water from the tank as possible. When no more water will exit the tank, place some old work towels inside the tank to help soak up the remaining water. This will help to keep it from getting all over the floor when you remove the supply hose. Keep in mind, there will still be some water left in the toilet, even when you are removing it. For the water left inside the seat section, use a cup to remove as much as possible.
Gently start rocking the toilet back and forth to break the seal. Once it is loose, you will be able to lift it over the flange bolts to remove it. It is heavy, so having a second pair of hands may be helpful for this part of the job.
Lift the bottom part of the toilet and set it down over the drainage hole. Both flange bolts should come through the holes on the base of the toilet with the base placed evenly over the wax ring. Make sure that the toilet is centered and properly seated.
Check around the toilet for any leaks, especially where the tank meets the base. Flush the toilet and check again for any leaks. About a week after using the new toilet, double-check the flange bolts to ensure that they haven't loosened. If they have, re-tighten.
