I purchased two Toto toilets 17 months age. Both have # SS114 toilet seats. Both have the same problem. That is that the soft close seat no longer soft closes. The bottom part (that you sit on) will soft close if it is lifted, but the top seat cover just falls when let go. They both worked for a little over 12 months (the warranty is 12 months). I've looked on Toto's website for fixes or adjustments, but didn't find any.
So my question is: Can these be fixed? And if not what OTHER brand of soft close seats to replace them with that is reliable and won't quickly fail?
