How To Fix Broken Toilets


To make simple toilet drain repairs, familiarize yourself with the many parts of the toilet and understand how it works. To understand how it works, take off the lid on the back of your toilet and flush.. You will see the chain lifting the flapper valve and water in the tank will flow through the flush valve, which opens into the bowl. The tank's waste water will be forced through a trap and into the toilet's main drain. When the drain is empty, the flapper valve closes and reseals the tank as the toilet is refilled with water by the ballcock.

Things You'll Need

  • Screwdriver
  • Gloves
  • Wrench
  • Familiarize yourself with the toilet parts. Remove the lid to the tank. Look at the handle, chain and lift arm, and flapper valve and that each are connected to one another. This will ensure that they are functioning.

  • Check the handle. If it is too tight, loosen it, and if it is too loose, tighten it. The lift arm might be broken or bent. If it is broken or bent, it may be out of adjustment, which would cause it not to flush. If it is out of adjustment, remove the lift arm and straighten it out. If it is broken, you must replace it. Purchase a lift arm at your hardware store; installation is fairly easy.

  • Jiggle the handle if you are having problems with the toilet constantly running.. If that does not fix the problem, adjust the handle or the lift chain assembly.

  • Check the float rod. Lift it above the tank's water level. Pull the float rod up above the water level. If the water stops running, push the rod down, bending it slightly, with the float resting roughly 1 1/2 inch below the surface of the overflow pipe. .

  • Check the float ball to see if it is touching the side of the toilet tank. If it is touching the side, bend the arm and reposition it away from the tank. Adjust the refill line that runs into the overflow tube in the tank if your water is splashing in the tank. The washers in the inlet valve may need to be replaced.

  • Check your float to see if it is leaking. If half the float or more is underwater, it may have a leak. A shutoff valve is below the tank. Turn it off. Flush the toilet until the toilet is empty. Unscrew the float . Check to see if there is water inside it by shaking it. If there is, replace it. If the flapper valve is loose, worn out or altered and will not seal the tank, the flapper valve must be replaced. Simply purchase a new one at your local hardware store.

Tips & Warnings

  • Parts of a toilet:
  • The ballcock -- the valve that supplies the water.
  • The float ball -- the ball that floats on the top of the tank's water.
  • The flush valve -- the connection of the flush and flapper valve set.
  • The lift arm -- the thin metal rod inside the toilet tank that connects to the handle to flush the toilet and lifts the flapper valve.
  • The main drain -- the pipe in the crawl space that carries waste water and waste to the septic tank or sewer.
  • The overflow pipe -- the tube to be fastened at the base of the tank.
  • The flapper -- the plug connected to the lift chain.
  • The tank -- the ceramic container located behind the bowl of the toilet.
  • The trap -- the drain the waste water in the toilet goes through when leaving the toilet.
  • If nothing seems to work, discuss the problem with your local hardware store.
