How to Fix or Replace a Broken Toilet Handle

No matter your toilet handle problem, the first step to fixing it is to turn off the water using the shut-off valve behind the toilet. Also known as the stop or supply valve, the shut-off valve is typically a round or oval knob protruding from the wall or floor behind the toilet. To turn the water off, turn the valve clockwise until it won't turn anymore.

Once the water is off, flush the toilet to drain the tank. This step will prevent water from spilling out while you're working and make it easier to access the toilet's components. Then carefully remove the tank lid and set it on a towel or other soft surface.

Now that you turned off the water and drained the tank, it's time to fix the handle problem. The steps for doing so will depend on what, exactly, is wrong with the handle.

How to Fix a Loose or Wobbly Handle

If your handle is too loose or wobbly, look inside the tank for the arm that attaches to your toilet's flush handle. At the base of that arm, you'll find a nut that secures the arm to the toilet. Usually made of plastic, but sometimes metal, the nut is likely reverse threaded, which means you'll need to turn it clockwise to loosen it or counterclockwise to tighten it. 

Use pliers or a wrench to loosen or tighten the nut until the flush handle arm is better secured and no longer wobbly. Just take care not to over tighten it—it should be just tight enough to fully secure the arm. 

How to Fix a Broken Lift Chain

When you look inside the tank, you'll notice a chain or wire that connects your toilet's flush handle to a flapper at the bottom of the tank. If this chain is loose or detached, it prevents the toilet from flushing properly. 

If the chain is no longer attached, simply reattach it to either the flapper or handle arm, depending on where it's detached. If the chain is properly attached on both ends but it's not taut, you can shorten it by moving the hook or clip that attaches it to the handle arm to a higher point on the chain or wire.

How to Fix a Stuck Handle

Over time, mineral deposits and rust can accumulate on a toilet handle—especially if you have hard water—which can cause the toilet handle to stick. If you suspect this is the case, inspect the handle's components for any mineral buildup or corrosion. If you notice any, mix a solution of one part water and one part vinegar, then use a cloth or brush to scrub the affected areas until clean. 

How to Replace the Toilet Handle

If your flush handle has broken components, like a cracked nut or a broken handle arm, it's usually easiest to replace the whole handle. You can buy a handle replacement kit from the hardware store. 

To remove the existing handle, use a wrench or pliers to unscrew the handle nut at the base of the tank. This nut is likely reverse threaded so you'll probably need to turn it clockwise to loosen it. Then remove the handle.

Once you remove the old handle, replace it with the new handle from your replacement kit. Attach the handle arm to the base of the tank by sliding the washer onto the arm, followed by the handle nut. Then use pliers or a wrench to turn the handle nut counterclockwise to tighten it. But don't tighten it too much since doing so can crack the porcelain. 

Finally, attach the chain or wire to the flapper and the handle arm. The chain should be taut but not so taut that the flapper can't close. You can adjust the chain's length by moving the hook or clip that comes with it up or down.

Once you've diagnosed and fixed the problem, turn the water shut-off valve behind the tank back on and let the tank refill. Flush the toilet to ensure it's working, then put the lid back onto the tank.
