Mansfield Toilet With A Broken Lever

An abundance of force onto the lever can cause the lever to break. The usual cause is an old worn seal, or flapper on the flush valve. The flush valve is designed to move freely with a one finger flush. If you have a tower valve that uses a seal it could be curved, or bent causing the piece that moves up and down to sit over the seal instead of on top of the seal. This will create a suction between the seal and flush valve. This can lead to using additional force on the handle to flush the toilet, and will eventually lead to a broken lever. If you decide to use a metal lever, you may end up snapping the top piece of the flush valve rather than the lever. Once you have discovered that the toilet has become harder to flush it is best to replace the flush valve seal, or flapper before it leads to a broken lever.
