A while back I noticed a slow leak from the toilet tank to the bowl in the guest bath, and got as far as putting it on my ToDo list, but then forgot about it. Then a few days ago we started noticing a periodic high pitched hum coming from somewhere. It lasted only a few seconds each time, and we couldn't figure out where it was coming from. Finally, I did note that it was occurring on a regular 19 minute cycle, so I positioned myself in various rooms at the appointed times, and finally isolated the sound to the toilet in the guest bath
It's a two piece 1.6 GPM Toto toilet that we purchased in 2003. To my memory it has never been worked on in the 11 years since we bought it. I can't find the model number, but a picture is below, along with the enlarged numbers from the toilet (top two superimposed images) and lid (bottom two superimposed images.
I think I read somewhere on this forum that the flappers are of two types, a blue and a red type, but I can't find that reference now. Here is an image of the tank and flapper, which looks green to me.
It being a Saturday, the plumbing supply store where we bought the toilet is closed, so I guess it will have to wait another couple more days.
But I did make a video showing the end of the 19 minute cycle. It is at
(I don't know why the video displays upside down on YouTube).
Apparently the slow leak lets the level drop a half inch or so over the 19 minutes, and the fill valve comes on just slightly--causing the high-pitch hum. I don't know if the bubbles coming from the bottom of the fill valve are normal or not. I suspect I have two separate problems with the flapper and the fill valve. Two days later the periodic humming has stopped, but the flapper is still leaking.
