Re-assemble valve by reversing the above
procedure. Note: If the main valve is worn out, (look inside cap),
cleaning will not suffice, and a Lavelle
replacement cap assembly = $3.99
will be required.
Note: if the fill valve turns on and off by
itself, or runs continuously without spilling into the overflow tube,
the problem is not the valve. The fill valve is running due to a
slow leak in the tank, probably caused by your flapper being either worn
out, or out of alignment.
