Toilet Flapper and Seals
Why do I need to adjust my flapper settings?
By opening or closing the white band, you are adjusting how long the flapper will stay open or how quickly it will close. The greater amount of holes that are exposed in the flapper, the quicker it will close. This feature of Korky toilet flappers helps our customers better match their original settings.
What are the signs that indicate I need to replace a toilet flapper?
The life of your flapper depends on a few external factors, such as what kind of water you use or if you use chemical tablets to clean your toilet tank. If your toilet is running or flushing on its own, sometimes referred to as ghost flushing, it is time to replace your flapper. For less than $20 and 10 minutes, you can replace your flapper, which often-times will fix your toilet issues. Most Korky flappers have a 5-year warranty. Our 2" Ultra 2X High-Performance Toilet Flapper (2017) and Large 3" 2X High-Performance Universal Toilet Flapper (3070) are both backed by 10-year warranties.
Which settings give you the longest flush?
For optimal performance and water use, we recommend matching the original toilet settings. A standard 2-inch flapper will follow these settings. For a large 3-inch flapper, view the instructions here. If you can't find your toilet model, reach out to our customer service team.
Toilet Flush Valve Seal
Can installing a new flush valve seal improve a hard-to-flush handle?
Yes! If the rubber of your seal starts to degrade, it can sometimes get sticky. That can make it hard to lift the canister with the tank lever. A fresh new seal won't have that stickiness to it, so you should get an easier lift from your tank lever.
Toilet Repair Kits
What is the difference between the 4010 and 4010MP?

The Korky QuietFILL® Platinum Complete Toilet Repair Kit (4010MP) includes the 528MP fill valve and 100BP toilet flapper. The flapper and fill valve both have the added benefit of optimizing water use in the toilet, and the ability to match original settings for the best flush performance.
Are toilet repair kits universal?
Korky toilet repair kits are designed to be universal and repair all toilet brands. Be sure to check what size flapper and flush valve your toilet uses. There are two sizes, standard 2-inch (more common) and large 3-inch (less common). If your toilet has a tower-style flush valve, you may have to replace the seal.

Are Korky fill valves quieter than older models?
Yes. Korky Fill Valves are designed with QuietFill technology and have been proven quieter in lab testing.
How do I adjust the water level?
For the Korky QuietFill Platinum series fill valve, refer to step seven of the installation instructions to adjust the water level in the bowl.
What is the difference between the 528 and the 528MP?
The QuietFILL Platinum Fill Valve (silver cap) is the high-performance version of the 528 QuietFILL Toilet Fill Valve (white cap). The 528MP (silver cap) includes a refill adjuster to deliver the right amount of water to the bowl to maintain the toilet's original performance.
How do you plunge a toilet correctly?
To plunge a toilet correctly, place your plunger into the toilet at a 45-degree angle, allowing water to enter the plunger head. Next, tilt the plunger upright and seal the outlet hole. Begin push-pull movements to unclog the trap way. Keep in mind that the power is in the pull movement, and remember to not break the seal of the plunger to the toilet bowl hole.
Wax Free Seal
Why is Korky WaxFREE better than a traditional wax ring?
Wax-free seals are better for a few reasons, the first and most obvious is that they are cleaner to replace than a traditional wax ring. Wax-free seals also have the benefit of not melting or freezing during weather fluctuations. Our wax-free is universal for any drain size or flange height, unlike wax, which is height-specific. During installation, you can change the height of the seal based on your closet flange, and also be able to seat your toilet multiple times if your alignment is off.
Can I install a wax-free seal if my closet flange is cracked?
No. If your closet flange is cracked or damaged, you must replace it before proceeding with your installation. Do not use sealants to fix a damaged closet flange, as this could cause a leak.
My toilet is unstable, should I tighten the bolts more?
Do not over-tighten the bolts if your toilet is wobbling after installing a wax-free seal. Over-tightening the bolts can crack the porcelain or your closet flange. Start by double-checking your measurements and making adjustments to which foam ring(s) you are using. If your measurements are correct, there is a chance that your floor may not be level, in which case, you can use shims to level the toilet.
