“Dad! The toilet handle is broken and it won’t flush!” Probably an easy fix I thought to myself. Better check it out to be sure.
I removed the cover from the toilet tank and saw that the lift chain connecting the handle to the flapper valve had broken. It was 5 years old and not surprising. A new flapper valve and lift chain costs about $5 and installs in minutes.
In this photo, the broken plastic lift chain is obvious. Don’t worry about the brown sediment on the bottom of the tank, it’s minerals that have precipitated out of the water over the years. The tank contains clean uncontaminated water.

Materials and Tools:
- Korky 1.6 Flapper Valve, includes the lift chain. Cost is about $5. Widely available at hardware and home improvement stores.
- Pliers
Installation:
The Korky installation manual is available here in addition to the following photos and tips.

New Korky Flapper Valve
Step 1: Shutoff the water supply valve to the toilet.

Step 2: Remove the old flapper valve by slipping it off the mounting arms. Remove what’s left of the broken lift chain from the lift arm.

Step 3: Adjust the lift chain by moving the metal clip to take out the slack when the lift arm is down with flapper valve is closed. I adjust the clip such that there is one extra link of slack. This avoids leaks and provides for a positive flushing action. Too much slack will allow the chain to kink and interfere with the flapper valve.
Adjust New Lift Chain
Step 4: Open the water valve to fill the tank. Flush the toilet to check for correct operation. If needed, readjust the lift chain by moving the metal clip up or down a couple of links. When you’re satisfied, cut off the excess lift chain to prevent it from getting tangled. I like to leave an extra 3 links in case a later adjustment is needed. Replace the tank cover.
