Topic: Unusual toilet flapper (1 replies, posted in Bidet & Toilet Repair)
Just removed an old toilet flapper and both holes to connect to the flush valve are different sizes. Never seen this before and just wondered if anyone knows what make it could be. Obviously the flush valve has 2 different sized connecting lugs too.
