I only need to flush the toilet twice about once every 200 times. Not sure what you are doing that would require it that often. And yes mine are for all intents and purposes brand new.
The one we had in the building I worked in for almost 28 years, never had a toilet that would flush just once when you deposited something in it. Sometimes it would take two or even three times. I bugged the crap out of the folks in charge to get them to put in a new toiled and they STILL haven’t. Both my husband and I have a bathroom and there are many times when we can’t flush it down well, and I have a brand new one. I don’t want to go into detail about our potty problems but this one’s hard to figure out.
