leaking tank
Kraemer

About every 2 min. my toilet tank refills. The refill is only for about 5 secs but it is continuous every 2 min. I have replaced the flapper-the original flapper shows no signs of damage or wear and even with the new flapper my tank is still refilling every 2 min.. What else should I be looking for?

Where is the waterline in set? If it is above the overflow tube, then you can replace the flapper all you want, it won't affect the "leak". Set the waterline so that it is at least a 1/4" below the top of the tube. There should also be a line stamped into the tank that the waterline should not exceed, below the line is fine, over is not.

If the flapper valve is good there is a chance it's misaligned and not sealing properly or the seat is messed up or debris is causing a bad seal. The overflow tube could be leaking. Maybe corrosion or broken. As mentioned, check the fill levels. Take the lid off and watch what is happening. It may become apparent once you watch it for a while. Some food coloring dripped in carefully may show where the leak is.

First make sure you got the right flapper for this toilet, flappers are not all the same. Make sure the flapper is solidly seated. It is also possible that the flapper seat may need cleaned or replaced.

No...the water is not above the tube. This leakage just began two days ago. The tank has been fine for the past 3 year. Thanks for your thoughts.

I will check the tube. Thanks for your suggestions.

Yes, the new flapper purchased is identical to the old flapper. I will check the seat a little more closely though. Thanks for your suggestions.

My sister's toilet has a similar problem. What I discovered was there was a factory-installed flaw in the porcelain where the flush valve is installed. The rubber gasket held for a while, but eventually it started leaking there more noticeably, and I couldn't even make a new gasket seal properly. I patched it together for now, but I need to replace the whole toilet this week.

I've ran across a few leaking flapper-seat/overflow tube assemblies that looked good to they eye but still leaked, giving these symptoms. If I have to go into a toilet for repairs the second time, I just remove the tank and replace everything in it and under it. If the old tank-to-bowl hardware is solid brass I reuse that, most of the new stuff is only plated and will rust in time. Not expensive, doesn't take long to do, and it's a guaranteed fix for anything except bad porcelain.

There are less than 10 parts in a toilet.

Wall nipple, angle stop, fill supply line, fill valve, flush valve, flapper, tank to bowl bolts and washer, toilet wax ring and toilet to floor flange bolts.

Replacing ALL OF THEM is not expensive and will give you the best results. You just have to pick parts that are compatible with your tank. Oh, almost forgot: you have to install them correctly.
