After arriving at the rental park model, I posted the blog entry Three Flush Toilet. The post was a tirade about the toilet needing three flushes to do what it should be design to do in one -- flush contents of the bowl.
Let's call it an operator error. About two weeks ago for some reason I held down the flush trigger a little longer than usual. A whole lot more water came swooshing into the bowl to send the contents to the sewer. With more testing and experimenting, I found that the toilet has a half -- and full flush. On rare occasions, I have had to do a second full flush.
I plead ignorance. Without operating instructions posted on the toilet, how was I to know the intricacies of how to flush this toilet.
