Step 6Install the lock nut
Find yourself an appropriately sized nylon lock nut that will thread onto the end of the rod.
I can't remember what size mine was, and they may vary between tanks anyway.
Make sure you use a nylon lock nut for this instructable.
When I first had this idea, I used a regular nut and everything seemed to work fine for a few weeks until I heard the toilet running. The nut had loosened and the rod had rotated so that it was now in a "V" position...which was actually using more water than before.
I threaded my lock nut onto the rod with the nylon insert facing away from the threaded plastic valve assembly. I figured the fatter end of the nut would have the most friction against the valve assembly in this direction.
Threading the nut nylon end first onto the rod can be tricky. It helps to flip the nut around and run it onto the threads "normally" once or twice to "cut" some threads into the nylon insert.
