I have two Mansfield toilets in our house, both of which use the #40 flush lever. Over the 12 years that I've lived in this house, I'd estimate I've had to replace each one at least four times -- it seems like every 18 months or so one of them breaks. The break point is always the same: just below where the plastic arm meets the locknut (marked with a red arrow in the image below).
Today it happened again, so I am going to have to buy yet another one of these cheap plastic things.
- Is this normal?
- If it's not normal, is there some underlying reason why this keeps happening?
- Is there an all-metal version of this that I won't need to keep replacing? I've been unable to locate anything, but I thought the folks here might know better than me...
Edited to add: Several people have asked whether the flush lever, before breaking, seemed to require an unusually large amount of force, as this might indicate that the flush valve seal needs replacing, and would lead to us placing too much force on the lever. The answer is No. We have not noticed any stickiness or resistance when using the levers. Each time the lever broke, the pattern was the same: it was turning very easily and working just fine, and then suddenly it was broken. Sorry if that ruins the most likely theory.
