You would think so Al but I think over the past three years I have not
had to change the rubber bands. I think I tightened them down a little
because the flapper was vibrating too much. I have noticed that rubber
bands tend to harden up if they sit around. Could it be that the slight
movement keeps them alive? In any event, it works real well for me and
it took about 1/2 hour to put together. BTW, I put two or three screws
on the pipe just as point to anchor the rubber bands.
Hope this helps.
