Introduction: Installation of Dual Flush Converter Kit From Home Depot
Installing toilet total repair kit/ dual flush upgrade purchased in a big box home improvement store. Kit is supposed to be a no tool no tank removal. This doesn't apply our canister style Mansfield brand toilet.

Step 1: Removing Parts
Shut off water and flush water from toilet tank. Remove tank from bowl by remove all bolts holding toilet tank to the bowl.
Remove original valve from tank & all parts. To remove this style of overflow tube it worked better to insert pliers through the bottom of the overflow tube an hold the nut on the outside while turning the tube clockwise. When removing flush handle remember that flush handle nut is a reverse thread.
Step 2: Installing New Valve
Follow instructions included in your kit, ours involved turning and adjusting the valve height and tightening one plastic nut.
Step 3: Installing New Dual Flush Converter
Install dual flush converter onto the new flush valve (to replace Mansfield, canister style flush valve per kit instructions).
Step 4: Installing Assembly From Step 4
Install whole assembly from step 3 into toilet tank. Rotate the flush valve and dual flush converter so that the control line isn't interfering with the water inlet valve. Also, make sure to leave room to access adjustments on dual flush converter. Finally, leave room to access tank mounting bolts.
This flush button uses a quick release to snap it to the flush control on the other side.
Step 5: Final Connection of Tubes
Now connect the refill tube to the overflow tube.
Step 6: Putting Everything Together
Now you can reattach the tank to the toilet and reconnect the water supply. It is a good idea to check the supply tube though. You should get a new one if yours is cracked or broken such as this one.
Step 7: Finished
There is a minor, unavoidable interference between the seat and buttons that doesn't effect operation. The flush adjustment procedure was straightforward and everything seems to work fine.
The bottom portion of the dual flush converter (step 3) did leak a small amount, probably caused by rotating the parts to clear the tank mounting holes. To stop the leak, just remove the dual flush converter valve (twist and lift), then push down and wiggle the lower portion of the assembly (last photo in step 3), then carefully re-install the dual flush converter valve.
There's a plastic stop on the inlet valve that holds the valve off (step 4, first photo) which was great for troubleshooting. Let the tank fill, then lock the valve off overnight and check to make sure the tank is still full.
We have a be nice policy.
Please be positive and constructive.
