• A bucket or bowl (to catch water when you remove the water line).

My TwoFlush dual flush system lever handles to not fit into the tank hole! The bushing looks to big. What do I do?
Go bushing-less!! Leave the bushing out, once completely installed the handles will have some play but the unit will function, Call 1-866-TWO-FLSH (896-3574) and they will send you a spacer that will improve the fit of the unit.
My lever arms came apart, what should I do?
We recommend gluing the two pieces together with household glue. Uninstall the arms, dry them, glue them, let them set for an hour. Then reinstall arms. You can do this one arm at a time so the toilet remains functional.
I cannot completely flush the liquid waste?
The large foam slider allows for more or less water to be flushed for liquid waste. Hold the riser tube firmly and slid the foam slider upwards for less water and downwards for more.
My TwoFlush dual flush system does not two flush any more what do I do?
What might be happening
is the handles are to tightly installed in the tank.
Uninstall the handles and reinstall without a spacer or in a configuration
that allows the handles to have some play in them. Also ensure that
the 2 arms do not contact or rub against each other.
