How to Replace a Toilet Flapper Valve
If you have a toilet that’s constantly running, the culprit is likely a leaky flapper valve. Over time, flappers may become cracked or warped, which can allow water to leak out.
In fact, a faulty flapper is the leading cause of leaking or running toilets, according to Fluidmaster, which manufactures toilet parts.
Flappers have two important jobs: They provide a seal for the toilet’s flush valve and control the volume of water released to the bowl.
Nothing lasts forever, but your maintenance habits may be accelerating your toilet flapper’s demise. Drop-in bleach tablets, for instance, may keep the tank clean, but they also cause flappers to wear out faster than alternatives.
Instead, use Fluidmaster’s Flush ‘n Sparkle Self-Cleaning Toilet System, which works with the flush valve to clean the tank only when you flush the toilet. This protects your toilets’ parts.
There are two versions: one that contains bleach, which you can use if you don’t have a septic system, and one that’s safe for septic systems.
Installation couldn’t be easier. Just hang the Flush ‘n Sparkle cartridge holder inside the tank, connect it to the fill valve and flush valve, insert the cartridge, and flush!
Bleach never enters the tank, so you’re cleaning the bowl without damaging your toilet’s precious parts.
Now, back to the toilet’s flapper. When they do wear out, flapper valves only cost a few dollars and are very easy to replace. Watch this video to learn more.
