Apparently my original toilet valves were cheap because they both had problems and I replaced both with fluidmaster valves some years ago.
Two problems were apparent immediately which I solved:
- The chain had enough length to tangle around the flush arm when flushed quickly.
- The anti-leak grabby thing needs slack in the chain so that the weight of the chain will make it hold and the tank won't top-off.
Making the chain shorter left no slack to weight the grabby hook thing so it disabled the anti-leak. To address both of these issues I added a metal washer to the chain to give it a little weight. This seemed to solve these two issues.
Here is the issue
After the switch I noticed that if it has been more than a few hours since the last flush the tank fills instead of flushing. So the anti-leak feature has probably saved me a ton in water cost over time. Once the tank fills the flush works normally.
It was a manageable annoyance, but now as my 19 mo old son is going to be potty training I want to teach him the proper one-flush way of doing things.
Is this going to be a flapper issue? I can't afford a plumber.
