Toilet has been running water constantly after flushing unless the water is turned off. So I replaced the flapper and now it seems to be still leaking, possibly worse.
Before I could have sworn if I turned the water off, it would stop running. Now when I turn the water off, it still runs until the tank empties. I am not 100% sure that this didn't happen before, but I am roughly 80% sure. Of course this doesn't make any sense, because it was leaking, making the trickling water sound constantly. So it is possible that it is exactly as before. I don't remember if the tank held the water before this. It drains pretty slowly.
In any case, I put the old flapper back and still the same...
One thing I noticed is that the water drains through a tube that the flapper is attached to. I see the water draining at the bottom of this tube even when the flapper is closed. Is THIS where the flapper actually drains through, or is there possibly another leak with this tube? I've compared it to another toilet in my house, and it appears that the water drains through this tube in the tank when the toilet is flushed. So this could still be an indicator of a bad flapper.
Pic of tube I'm talking about below. What's interesting is that the water in the tank drains down to where the tube is stuck into another tube. Slightly just above the line where they connect. But then it stops draining. So I'm not sure it's the flapper, as I would think that if it was the flapper, it would drain all the way down. Then again, I am also not sure that it isn't a leak in the seal where the two tubes are connected, as it doesn't drain right down to this point, just a few millimeters above it. Shouldn't it drain right to the line if this is where the leak is? Or just not enough pressure from the weight of the water to force it through the slight leak at that point? And if so, easier to just replace the toilet? I've done that before and although one of my coworkers has complained about how hard it is, I find it relatively easy and I've heard that if the flapper repair kit doesn't fix the issue fixing the internals of the toilet is a big job. Might be more time involved than direct cost, but would prefer to just be done with it.
I'm about to head to Home Depot to get a full fledged repair kit, but if it doesn't work, I might look at replacing the toilet. I've replaced toilets before, and from what I understand the repair for the leaking tank is a big job. SO it might just be easier to replace with a new toilet.
