Drop-in toilet tank cleaners can be hard on a toilet. Many contain strong chemicals, such as chlorine bleach, that sit in the tank water all day and can wear out the rubber flapper, gaskets, and seals faster, which can lead to leaks and a running toilet.
Why They Can Cause Problems
A toilet tank holds the same water for hours between flushes. A tablet dissolving in that water keeps rubber and plastic parts soaking in cleaning chemicals. Over time, flappers can warp, crack, or soften. Fill valve parts and tank-to-bowl gaskets can also break down. Some toilet makers warn against these products in their care instructions.
Signs Your Tank Parts Are Wearing Out
- The toilet runs or refills on its own
- Water trickles into the bowl between flushes
- The flapper feels soft, slimy, or stiff and warped
- Leaks appear where the tank meets the bowl
- Colored water from the tablet keeps showing up in the bowl long after flushing
Safer Ways to Keep the Bowl Clean
Clean the bowl with a brush and a cleaner made for porcelain once or twice a week. If you like the convenience of an automatic cleaner, look for products that clip onto the rim of the bowl instead of sitting in the tank. Wiping down the outside of the tank and under the rim also helps.
If You Have Used Them for a While
Stop using tank tablets and check the flapper and fill valve. If they look worn, replacing them can stop leaks and save water. Bring the old flapper to the store or note the toilet model to get the right size.
A dye test in the tank can show whether the flapper is still sealing.
If your toilet keeps running after you stop the tablets, getting the tank parts replaced usually solves it. If other fixtures are acting up too, you can have the rest of the bathroom checked at (833) 603-1840.
