How do you fix a toilet handle arm?

A loose or broken toilet handle arm is a common issue that can often be fixed with some basic tools and plumbing knowledge. In this comprehensive guide, we will walk through the steps needed to remove, diagnose, and replace a faulty toilet handle arm so you can get your toilet flushing properly again.

What is a Toilet Handle Arm?

The toilet handle arm, also known as the toilet flush lever, is the arm that connects the flush handle to the flapper valve inside the toilet tank. When you push the handle down, it lifts the flapper valve via the handle arm, allowing water to rush from the tank into the toilet bowl. Once the tank empties, the flapper valve closes, and the tank refills.

The handle arm is made of metal or plastic and connects to the flapper valve lift rod with a ball joint. It’s this ball joint that often becomes loose or corroded over time, preventing the proper transfer of motion from handle to flapper. Replacing this small part can often fix phantom flushing issues or toilets that keep running after flushing.

Tools and Materials Needed

Fixing a toilet handle arm is generally a quick and straightforward repair. Before getting started, make sure you have the following tools and materials on hand:

  • Adjustable wrench
  • Needle nose pliers
  • Replacement handle arm kit
  • Rag or paper towels
  • Gloves (optional)

Handle arm kits can be found at most hardware stores and home centers for around $10-15. Kits contain the metal arm and necessary washers, bushings, nuts, and fasteners. Make sure the replacement matches the original handle arm style from the manufacturer.

You may also need a screwdriver to access the tank hardware beneath the lid. Make sure to turn off the toilet’s water supply before beginning work.

Removing the Old Toilet Handle Arm

Start by taking the toilet tank lid off and setting it aside in a safe place. Flush the toilet one last time to empty the tank. Use a rag or towels to soak up any remaining water in the tank.

Disconnect from Handle

Look inside the tank for where the arm connects to the white plastic flush lever via a small lever nut. Use an adjustable wrench or needle nose pliers to loosen and remove this nut. Detach the arm from the flush lever.

Disconnect from Flapper

Next, locate where the handle arm inserts into a lift rod that connects to the rubber flapper valve. The arm likely has a ball joint that drops into a hole or opening at the end of the lift rod. Carefully maneuver the arm to detach it from the lift rod. You may need pliers to work it free.

Remove Arm and Lift Rod

With the arm detached at both ends, you can now fully remove it from the tank. Note how the lift rod attaches to the flapper valve before removing. In most cases, it’s held on by a simple wire loop or retaining clip. You’ll need to reattach the lift rod the same way when installing the new arm.

Also, inspect the condition of the lift rod. If it is severely corroded, bent or cracked, a replacement lift rod may also be needed.

Installing a New Toilet Handle Arm

With the old arm removed, installing a new one is straightforward. Make sure the water supply is still turned off during this process.

Attach Lift Rod

First, insert the lift rod back into the flapper valve opening just like it was originally attached. Secure it with the flapper clip or retaining wire.

Connect Arm to Flapper

Now insert the new arm’s ball end into the hole or opening at the top of the lift rod. It may click or snap into place. Give it a light tug to make sure it is securely connected.

Connect Arm to Handle

Move back up and connect the opposite end of the replacement handle arm to the flush lever. Insert it into the appropriate opening and secure with the small handle nut. You want no looseness or wiggle room when properly attached.

Activate and Test

With the new toilet handle arm securely installed at both ends, turn the water supply back on and allow the tank to fill. Press down on the flush lever and make sure the motion transfers smoothly to lift the flapper high enough for a full flush.

If the flapper does not raise all the way, adjust the arm position or connections points as needed. You want it to open without resistance and close fully when the handle is released. Flush a couple times to verify proper operation.

Common Toilet Handle Arm Problems

Some common issues that occur with toilet handle arms include:

Loose Connections

Over time, the nuts and fasteners that hold the arm in place can come loose. This affects how the arm transfers motion from the handle to the flapper, resulting in a poor or incomplete flush.

Corrosion

Corrosion buildup can deteriorate the arm and lift rod over many years, eventually breaking down the material and ball joint connections. A corroded handle arm should always be replaced.

Cracks

Repeated stress can cause plastic handle arms to crack near connection points or in the middle of the rod. Any cracks mean the arm needs replacement.

Bending

Applying too much force when pushing the toilet handle can bend metal arms over time. A bent arm may still function but is more prone to detaching or breaking off completely.

Troubleshooting Toilet Handle Arm Problems

If you’re having trouble with a loose, disconnected or non-functioning toilet handle arm, try these troubleshooting tips:

Check Connections

Inspect where the arm attaches at both ends. Tighten any loose nuts or fasteners securing it in place. Proper positioning and no wiggle room is essential.

Remove Corrosion

For corrosion buildup, remove the arm and use steel wool or abrasive brush to gently scrub away oxidation. Replace any deteriorated parts.

Adjust Flapper Chain

If the flapper valve isn’t lifting high enough, the chain connecting it to the handle arm may need adjustment. Loosen the chain and adjust length as needed.

Check for Cracks

Thoroughly examine plastic arms for any fine cracks or damage. Even hairline cracks mean the part should be replaced to prevent breakage.

Replace Bent Arms

Do not attempt to bend severely bent metal arms back into shape. Always replace bent arms with new ones to restore proper flushing function.

Preventing Future Toilet Handle Arm Problems

To help prevent toilet handle arm failures down the road:

  • Avoid applying excessive force when depressing the flush lever.
  • Make sure the arm has some play and is not too tight.
  • Occasionally remove arms to clean out any grit or buildup.
  • Lubricate ball joints and pivot points with plumbers grease.
  • Replace plastic arms every 5-7 years as preventive maintenance.

Proper toilet handle arm care and maintenance will keep this small but vital toilet part working smoothly for many years.

When to Call a Plumber

While a loose handle arm is an easy DIY fix, some situations do warrant calling in a professional plumber, such as:

  • The arm is severely corroded or damaged beyond repair.
  • Removing the old arm proves too difficult.
  • You can’t get the new arm properly aligned or connected.
  • Other tank parts like the flapper, lift rod or fill valve also need replacing.
  • There are leaks coming from the tank connections.
  • You don’t feel comfortable completing the repair yourself.

An experienced plumber can quickly diagnose any issues and get your flush handle operating smoothly again.

Conclusion

Replacing a broken or malfunctioning toilet handle arm is an easy, inexpensive DIY project that can resolve many common toilet flushing problems. With some basic tools and plumbing knowledge, anyone can remove and install a new handle arm in under 30 minutes. Just be sure to turn off the water, disconnect supply lines, check for corrosion, and properly secure all connections. A smooth, properly functioning handle arm is key for a strong, reliable flush.
