How to Install a Toilet Lift Arm

Toilet lift arms get a lot of use and after a period of time fail to operate.

Though the part is not expensive, it will not take you long to appreciate its worth after lifting the lid a few times and plunging your hands into the cold water to flush the toilet. There is no need to call a plumber unless you are ready to pay about ten times the value of the part for a service call. .

Shut off the water to the toilet by closing the shut-off valve usually located at the base of the toilet near the wall.

Remove the tank lid and lift the chain to manually flush the toilet. Hold open the drain plug which covers the drain inside the tank until most of the water is out.

Remove the nut holding on the lift arm with a pliers and take out the defective part. Notice the threads are reversed on the nut, so you will be turning the nut in the opposite direction.

Insert the new lift arm and tighten the new nut with a pliers. Be careful not to over-tighten the nut, or you could crack the tank.

Connect the chain to the lift arm using the attached hook.

Replace the tank lid and turn on the water.

Things You Will Need

  • Pliers


  • Different areas on the lift arm connect the chain. If the toilet does not completely flush without holding the lift arm down, hook the chain closer to the end of the arm.
