Repairing a Leaking Toilet, How To Repair a Toilet

Leak-Stopping Steps to Save Water and Save Money

Because a leaking toilet will waste water at an astonishing rate - as much as 750 liters a day - it deserves your full and fast attention before it dents the local water supply overall. Happily, if you can identify the problem, it’s usually easy to fix. There’s an 8-step process that should help you determine if your toilet has a leak, and fix it. First, remove the lid from the toilet tank; add a few drops of food coloring or a capful of colored fabric softener to the water in the tank; wait 10 minutes; check the water in the toilet bowl for signs of the added color. If it does, your toilet has a leak. Next, shut off the running toilet; in the tank, mark the water level with a marker or pencil; wait 10 minutes; if the water level has fallen below the mark, the flush valve is causing the leak. If the level doesn’t fall, check the overflow tube to see if water is running through it. If so, you’ll need to replace the toilet fill valve.

Where the Toilet Meets the Floor . . .

Another cause of a leaking toilet and other toilet problems is at the seal where the toilet meets the floor. This is a bad leak that will eventually rot the floor, the subfloor, or even the framing around the toilet and allow sewer gas to escape into the bathroom. A small pool of water where the toilet meets the floor may indicate that much more water is trapped beneath it. If you’re fortunate, this will require only  that you replace the pan connector (the piece that fits between the bowl of your toilet and the wall) and then set the toilet back in place. You’ll have to remove the toilet, but you can accomplish the entire project within about an hour.
