I really hope someone can help me solve this problem.
I have three identical toilets in my house, two have had the flushing mechanism replaced (one is still the original). Both replacements are a Dura Silent Flush mechanism. The one that was replaced most recently, has not worked really well since it was replaced… the others work fine. All the innards look identical on the two with the same (replaced) mechanisms and I have tried simply swapping the lids, to make sure it was not a button issue.
The problem is with the flush, it barely works on the half flush side and only works on the full side if you hold the button in (and, even then, the flush is not as robust as the other toilet). I can push the levers with our the lid and the toilet works.
Any clues as to what the problem might be? I am happy to send photos or video if you can help me identify the problem.
