How To: Fix a Constantly Running Toilet

031008_toilet.jpgOur friend mentioned the other day that their toilet handle kept sticking in the 'down' position and consequently the toilet would keep running for hours. They were going to call a plumber to fix it but we thought it sounded like an easy home repair. And since home repairs sometimes frighten us (we don't want to make an even bigger problem) we thought this would be good practice (um, someone else's home). To the internet we went, the solution after the jump:

First thing is to diagnose the problem. A running toilet could be a number of things (all fairly simple). So we diagnosed the problem and it looks like the toilet needs a new flapper valve since it is a slow continuous running leak of water from the tank into the bowl. We found a really helpful step by step for how to change it on Hammer Zone. We also ran across a bunch of useful toilet related how to's on suite 101 that we've kept bookmarked for future projects. We'll let you know how it turns out!

How many bathroom repairs do you do yourself?

Our toilet was constantly running because the handle got stuck in the "down" position, and it wasn't the flapper thing, it was the actual handle, or rather the metal arm on the inside of the toilet that's attached to the handle--it had gotten deformed so it would get stuck. We just bought a new handle-and-metal-arm combo from the hardware store--it was about $8--and I fixed it. I was very proud.

My upstairs toilet was running, and I was about to call the plumber, when I decided to have a look myself. I discovered that the chain (which is plastic, and light) had floated into a weird position and then a link of it got stuck on the arm, and it shortened and held the flap up, making the toilet run. I just had to untangle the chain to fix it. It's happened a few times since then, and I get a little thrill every time I control the situation.

My boyfriend dropped the deodorant in the toilet bowl and then, for some reason that still hasn't been sufficiently explained to me, flushed the toilet. Which firmly lodged the aforementioned deodorant in the floor outlet.

I ended up having to remove the entire toilet to pull out the deodorant. And then I replaced the old toilet gasket (unrelated repair). And then I re-installed the toilet.

How 'bout them apples. Yeah.

Sometimes the problem is that the floating bit isn't floating any more because it leaks. I've remedied this by putting a plastic bag around it and secured it with a twist tie!

I had that exact problem and spent a whole year pushing down the flapper every time I flushed. Finally, my (new at the time) boyfriend took me on a field trip to Lowe's to buy me a new flapper and then fixed it for me. He was seriously my hero. That was the best "Cure" ever done in this apartment. (Do you know what a pain it is to take the tank lid off and reach down in there every time you flush?!) :-)
