Recommended tools for toilet installation

  • Regular Screwdriver
  • Wrench
  • Carpenter's level
  • Plastic scraper
Removing your old toilet
  1. Shut off the toilet's water supply and flush the toilet until the tank is empty. Use a sponge to wipe it dry.
  2. Disconnect the water supply line from inside the tank.
  3. Remove the bolts that connect the tank to the bowl and remove the tank. You may need to use pliers to hold the nut in place (from underneath the tank).
  4. Wipe any excess water from inside the bowl.
  5. Remove the bolts at the base of the toilet. This can be difficult, so using oil to loosen the bolts may be necessary. If they cannot be removed, you can use a hacksaw to cut them off.
  6. Rock the toilet back and forth to break the seal between the toilet and piping. Remove the toilet and put it aside.
  7. Wearing rubber gloves, stuff the drainpipe with a rag to keep the fumes from escaping into your bathroom.
  8. Remove the closet bolts from the closet flange, and with a plastic scraper, remove all old plumbers putty from the floor.
Installing your new toilet
  1. Install new closet bolts into closet flange (see Fig 1).
  2. NOTE: You can pre-cut the closet bolts to the desired length to put on the bolt cap by doing the following:
  • Temporarily install the closet bolts
  • Set the toilet and place the washers and nuts into the bolts
  • Mark the length needed
  • Take toilet out of the place and remove the closet bolts
  • Cut the bolts to required length
  1. Turn new toilet upside down onto a soft surface to avoid scratches and place new wax ring around the waste flange (see Fig 2).
  2. Run a bead of plumbers putty around the base of the bowl to get a water-tight seal with the floor.
  3. Lower the toilet onto the closet bolts so that they project through the mounting holes in the base of the toilet (see Fig 3). Make sure that the toilet is level, and place shims under the toilet if it's not level.
  4. Using a rocking motion, press the bowl down to seat the toilet into the flange.
  5. Loosely install rubber washers, followed by metal washers and nuts onto the T-bolts. Alternately tighten the bolts until toilet is firmly seated on the floor. Be careful not to over-tighten them, as this can damage the toilet. Tighten the bolts slowly and with caution.
Installing the tank
  1. Turn the tank upside-down and install a rubber gasket around the threaded outlet. Turn the tank upright. (see Fig 4)
  2. Insert tank mounting bolts with metal washer followed by rubber washer from inside the tank through the mounting holes. Secure with metal washers and nuts on the other side by using a wrench.
  3. Lower tank onto bowl so that tapered end of gasket fits into bowl water inlet opening.
  4. Use the metal oval washer and winged nut to secure tank to bowl, tighten the nuts alternately until the tank is seated evenly on the bowl surface, making necessary adjustments. CAUTION: Do not over-tighten the nuts, severe damage may accur to the tank and bowl.
  5. Connect the water supply line, tighten coupling nuts and turn water back on.
  6. Installing the tank lever handle
  7. Turn clockwise to remove plastic nuts from lever arm.
  8. Insert lever arm through the hole in the tank. Screw the plastic nut counterclockwise to tighten it (see Fig 5).
  9. Hook the chain onto the lever. With the lever at rest, the chain should only be long enough for the flapper to close.
