commode occasionally runs already replaced flapper still doing it

Ok, just checked it. A little hard to see since it's black PVC, but upon looking with flashlight it seems fine. I ran my finger around it and felt smooth all the way.

I have a slight problem where I can hear my commode running. It does this for about 15 seconds maybe 4-5 times a day. At first I thought the flap needed replacing and did that, but still doing it. To help maybe rule out the flap completely, I placed a weight on top of the new flap, the colored the tank water. After an hour, I could see some color in the bottom of the bowl. I am using a Fluidmaster valve, could this be going bad? Thanks.

Is it possible the float valve is set too high, and water is running into the overflow pipe ?

Did you check the rim of the opening the flapper sets on for a defects ?

The top seal can be replaced on a Fluidmaster...something like a quarter turn, after you remove the black cap. You may even find it dirty...

Apparently that is not an EPA approved commode. They do that to tell you to replace with a government approved very low flow commode. If you don't in about a week it will explode.

I heard yours exploded, right?, LOL!

You still fiddle with that? I'd replace the fill valve as well. I had always good luck with Korky brand. Logic tells if flapper does not fix the problem, next thing to try is new fill valve.

Unless it's overflowing into the overflow tube, no. If the valve is leaking and the flapper is sealing, the tank would be overflowing.

I had no trouble getting flappers for my toilets when I first lived h here, but the hardware store I went to closed, and no place else sold the model I used. Then I was at a custodial supply house that I guess really was wholesale (because it was so cheap), and required a letterhead statement from a business to shop there.

The flappers, same name brand, were about a dollar a piece (Isn't that cheap?) so I bought 24 of them!

The first one worked fine, but the next one took 4 months to seat right. I would take the lid off and use a stick to push it into the pipe, and then it would seal until the next time I flushed the toilet. After the 4 months, it's been working fine for years.

I haven't needed a third until now, and I'm waiting to see if it will be perfect like the first one or the same way.

You can prevent this by planting a rose bush in the toilet.

And you will FERTILIZE it daily :)

I have nothing here approved by the EPA. They and them that follow them are limp wristed types all.

Did you know that FrozenNorth was a net cop?

That is because of all the weight of the BS it had to support and wasn't up to the job of holding him and his "friend" at the same time. He should be using the hopper at the cement plant...

I replaced the Fluidmaster valve this morning, and the flapper last week. The food coloring test is still showing up at the bottom of the bowl after about 15 min. Not sure what else to do. I am considering trying the Korky kit that supposedly "repairs" the flapper by using a ring that is siliconed in place under it. I suppose if that doesn't work, I'll have to pull off the tank and replace those parts.

Perhaps if you quit top-posting, the Toilet Gods would be appeased and stop your toilet from leaking...

Amen

I used the Corky kit which basically provides a ring that is silicone applied to the seat. It says to allow 15 min after resetting, but I let it sit for 2 hours before refilling the tank. Same results, I can see traces of food coloring working from the tank into the bowl. When I shine a flashlight down the overflow tube, I don't see anything leaking in from the side.

I guess I'll shut off the water and see what happens. Just for clarification, by tank "leaking down" are you meaning the water level dropping inside the tank versus not? Since the occasional running of the commode is so infrequent, I guess I'd better carefully mark the initial water level. Since the family needs the water tonight, I will have to try this tomorrow.

Let it fill, then turn off the water supply. If the tank leaks down, it's the flapper. If it doesn't leak down, its the valve.

There is, but I don't trust it and leave it alone. A few years back, I had serious issues getting it to fully close off the supply line and it wanted to start leaking, so I carefully opened it back up and left it that way. Definitely don't want to have to start soldering the pipes with a new valve!
