My toilet runs by itself for a short amount of time occasionally. I've read on the internet that that is caused by a bad flapper or bad flapper seat. It’s only been doing this in the past week or so.
All of the internal parts of the toilet have been replaced by the plumber recently. They also were replaced less than a year ago. I'm not impressed with my plumber but my landlady is paying for it and likes them so ok.
Before I condemn the plumber or the parts he uses, I want to be sure it wasn't anything I did.
The toilet has overflowed too many times in the past. I now flush my poop down in the first flush and take as many flushes as I need to flush however much toilet paper I need to use. If I hear the whole thing go boom as it hits a horizontal pipe nearby, I know that everything has gone down.
Additionally, in an effort to prevent the toilet from overflowing I have done two things:
(The toilet is using a Wolverine Brass Big Orange harsh water flush valve #57732 and a Fluidmaster Pro 45 fill valve.)
1) I lowered the water adjustment adjustment rod for the float cup to a lower position.
2) I put a plastic jug in the tank to take up space, and filled it with water to keep it in place.
The water level in the tank is noticeably lower maybe by an inch or more than what it used to be measured by where the stain on the tank wall is.
Have I caused this new problem of the toilet running by itself? If so, what do I do to stop it?
One thing the plumber said might play into this. He said that the new parts he put in this latest time would be a more powerful flush than what had been in there before. He thought that would be good for preventing the toilet from backing up. It did have a more powerful flush but it also caused the toilet to overflow more often when it backed up. That’s why I lowered the level. I want less water in that bowl so I don’t have to worry about it overflowing again. I still watch it (and listen to it to be sure it makes all the right noises) to be sure it flushes ok.
Many thanks. I always appreciate the help I get here. I'd be happy to add any info if needed.
