Unhappy Toilet still drips and refills

I've tried 2 new fill valves, toilet to tank seal, flush valve and tried 2 flaps, cleaned the flap seat many times, different chains...

you can hear like drips abt 5 secs apart, then the water runs to fill the tank for abt 10 secs. every 15 mins.
what am i missing?? or what should I replace or adjust again?

Put some food coloring in tank and see if water is going there. Last time I had this problem was tank to bowl seal.

Where is the bowl fill tube that replenishes water to the bowl through the overflow located? Is it clamped above the fill tube and pointed so water flows into it, or is it just shoved down the tube? If shoved down the tube it will siphon water out and cause occasional refills.

thx... comes from the side of the fluidmaster fill tube to the clamp above the top of the flush valve. not inserted at all into the flush valve tube.

i tried that a while back... it was going in so i replaced the bowl to tank seal, but I'll try it again. If it migrates to the bowl, is it another tank to bowl seal or another flush tube valve?

EDIT: it is leaching into the bowl. So, which alternative to fix?

Its the flush valve and flapper. What brand/model toilet do you have?

You need to buy them together in a kit... replacing a flapper on a old flush valve often doesn't remedy the leak. And some finnicky ones need brand specific parts... like Kohler.

OK, I'll try it again... this has been doing this for months and I'm sure I put in a new flush valve kit, and it still dripped, and I then put a seemingly better flapper on it. thanks

The other possibility, but I would imagine you would have observed it by now, is that sometimes the flush valve gets caught up in the chain and prevents it from dropping properly to completely seal the tank.

Over the years I have had the best luck with a brand called "Korky". There are several slightly different models, you have to have the right one.

I bought a Fluidmaster PerformMAX kit so I will replace the whole flush valve. I'll edit later if it's successful. The replacement flapper seemed good, fairly heavy, had a nice rubber connection line to the handle... no way to get twisted up like chains I've used in the past.

It's not usually a flush valve issue. It's a leak between the flapper and the seat.... where the red arrow is. Be sure to change the entire assembly in the circle and not just the flapper.
