The Toilet Tank Parts You Need To Know
The diagram below illustrates the key parts that work together to make sure your toilet flushes properly. To replace a toilet handle, we just need to understand these 4 parts:
- The Toilet Handle (also called a flush handle or flush lever)
- The Trip Lever (also called a lift arm or handle arm)
- The Chain (also called a flapper valve chain)
- The Flapper Valve
As you can see in the diagram above, (A) the toilet handle is attached to the trip lever, (B) the trip lever is attached to the chain, and (C) the chain is attached to the flapper valve. It’s really just one mechanism made up of several different parts.
Pushing down on the toilet handle forces the trip lever to move up. This upward action also pulls the chain up, which then opens the flapper valve. Once the flapper valve is opened, the water in the tank, using the force of gravity, flushes down into the toilet bowl. That’s really all there is to it.
Now that you have a basic understanding of the parts involved in the toilet handle flushing process, let’s start by replacing a toilet handle that can’t be fixed. You will be amazed at how simple it is.
How To Replace Toilet Handle: Instructions
Most probably your toilet’s handle has cracked, especially if it’s plastic. Other common breaks occur with the bolt that attaches to your toilet handle or with the long plastic piece (the tank lever) that attaches your toilet handle’s bolt to a chain.
Regardless of how your toilet handle breaks, here are your steps for replacing the entire toilet handle flushing mechanism:
1. Buy A New Toilet Handle
Most handles fit most toilets, but there are exceptions to consider. For example, does your handle fit on the front or side of your tank? Before you go shopping, here are a couple of broken toilet handle tips that will keep you from having to make several trips to the hardware store:
Find the brand and model number (or model name) of your toilet. Often, the brand name is displayed on the outside of the tank while the model name/number is behind, underneath, or on the inside of the tank (don’t worry, the water inside the tank is clean). Write down the information and take it with you. You might get lucky and find an exact match.
Also, remove and bring with you the actual toilet handle mechanism — both the handle and trip lever (that long plastic or metal piece). Or simply take several photos of the toilet handle mechanism (both outside and inside the tank).
2. Remove The Tank Lid
Now that you have your new handle parts, here’s how to remove the tank lid before you replace the toilet handle (heck, this part is so easy, we don’t even need to show you a photo):
- Carefully remove the lid from the top of your tank; most residential toilets are made out of porcelain which can be chipped or damaged easily. You don’t need to be as careful with wood or concrete toilets.
- Place the lid on a thick towel and wrap it. For more protection, please it gently in the bathtub where no one can trip over it.
- NOTE: This project does not require you to turn off the water to your toilet.
3. Unhook The Chain
The next step in replacing your broken toilet handle is nearly as easy as removing the tank lid:
- Unhook the chain from the trip lever (but do not unhook the chain from the flush valve). Remember, the trip lever is that long plastic or metal piece that’s between the handle and the chain.
- NOTE: Remember which hole — there are usually 3 or 4 holes in the trip lever — you unhooked the chain from. Later, you will need to rehook the chain to that same hole in the new handle mechanism.
4. Unscrew Nut And Remove Handle
For this step, you might need a crescent (or adjustable) wrench:
- Loosen the nut that holds the handle in place. It is located on the opposite side of the handle, inside the tank. You might be able to unscrew it with your fingers. But if it’s on too tight, grab a wrench that fits.
- The nut is threaded in reverse (it’s a left-handed nut), which means you need to turn it in the opposite direction that you are used to. So make sure you turn the nut to the right (clockwise) to loosen it.
- With the nut now removed, pull out the handle from the toilet. Allow the tilt lever to slide through the handle hole as you pull out the handle.
- NOTE: Use a firm grip when loosening the nut, but be careful not to use extreme force as the wrench could slip off the nut and break the porcelain. If the nut still won’t loosen, spray it with WD-40 oil lubricant. This should remove any rust build-up that’s holding the nut in place.
5. Insert And Attach New Toilet Handle
The really fun part of how to replace a toilet handle is when you begin to see the light at the end of the tunnel. Now that you’ve successfully removed that broken toilet handle, you’re now ready to replace it with a brand new toilet handle mechanism.
- First, clean the hole where the toilet handle goes — inside and outside — with soap, water, and a sponge. Once thoroughly cleaned, dry off the area with a towel.
- Next, remove the nut from the new toilet handle.
- Slip the tilt lever all the way into the hole (from the outside).
- Now place the nut back onto the tilt lever (see photo below) and slide it up until it reaches the handle’s threaded base.
- Screw the nut onto the base by turning it counter-clockwise (to the left if you’re facing it).
- NOTE: Make sure you have a tight fit without overdoing it. Use a wrench if you need to.
6. Attach Chain To New Tilt Lever
You’ve reached the final step in how to replace a toilet handle. Now let’s finish what we started:
- Re-attach the flapper valve chain to the tilt lever.
- Make sure to clip the chain onto the same hole of the new tilt lever as it was in the old tilt lever.
- Now flush the toilet to see if everything works properly. If so, you’re done!
- NOTE: If the chain is set too tight, the flush valve won’t fully close, causing water to continuously leak into the toilet bowl. If the chain is too loose, not enough water will drain into your toilet bowl, causing a weak flush. In either case, simply try re-clipping the chain to a different hole in the tilt lever. Test it each time until you have the perfect fit.
