Product Overview

Only Fluidmaster has toilet flappers with built-in Microban protection. The Microban protection keeps the flapper cleaner by fighting flapper breakdown due to bacteria on the flapper itself. Toilet flappers made with Microban technology are more resistant to premature deterioration than other flappers. The Microban additive operates on the cellular level to prevent uncontrolled growth of microorganisms that can damage the flapper. The 502 Universal PerforMAX High Performance Toilet Flapper for 2 in. flush valves works best in toilets with 1.28 - 3.5 Gal. per flush or higher. The 502 is adjustable for optimum performance and water savings, is chlorine resistant, and has a solid frame for ultimate reliability. Flappers with a solid frame do not twist and provide the best seal. Replace or fix your toilet flapper with a Fluidmaster toilet flapper.

Customer Questions & Answers

Fluidmaster Adjust-a-Flush 2" Toilet Flapper ---how does this adjuster work? What happens in turning the dial?

Asked by: Anonymous
Set to "9", the flapper will stay up for a long time. Smaller numbers will make it drop faster, limiting the amount of water that makes it out of the tank before the flapper stops it.

How to get the flapper to go down by itself?

How to get the flapper to go down by itself?
Asked by: nuhippy
I just sat over the exposed back basin of the toilet with a phillips head screw driver and made very minor adjustments to the screws on the inlet pump. Then I clipped the plastic off the flush handle innards in the water basin. That way as the flap descended it would not catch anything on the way down and restrict the toilet from stopping when needed.

how do I treat ghost water loss?

I hear water running out and I hear more water going in. What is going on?
Asked by: seacaptain1
The most common solution for your situation is to replace the flapper. As the flapper ages the material it is made of can disintegrate causing it become distorted and not to seal correctly on the tank discharge valve. You may also try lifting the flapper valve and looking for an obstruction that would cause the flapper not to seal properly.

W can this be used in a BRIGGS 4438 tank flapper

I need a flapper for a Briggs 4438.
Asked by: nanato3
You should be able to use this flapper, the part number is 502 if your flapper is designed with the two plastic clip on arms. just measure the chain length, once you remove the old flapper it should be equal to the new 502 flapper. snap this flapper on, clip the chain to the flush arm middle hole. and give it a try. make adjustment as needed.

2 in. Universal PerforMAX High Performance Toilet Flapper with Microban is rated 4.3 out of 5 by 292.
Rated 5 out of 5 by from The 2 in. Universal PerforMAX High Performance Toilet Flapper with Microban from Fluidmaster was ... The 2 in. Universal PerforMAX High Performance Toilet Flapper with Microban from Fluidmaster was an easy replacement. Un-click old flapper by lifting up on prongs on hinge stubs and click the new one in. Next size the chain and set length of pull chain. Be sure to remove excess chain. I set the setting on flapper to 5 and it works well.

This is the only flapper that I could find to replace the original flapper on this particular designed tank. It attaches to a narrower tube than what is standard and snaps on very good. The snap on handles are made of sturdy material unlike most on the market which is made out of one piece rubber. This justifies a couple of dollars more. I had actually gone through a couple before I found this one. I had previously lost a lot of water from the tenant apartment where this toilet is. It appears to be tight and holding the water without leaks. However, it is too early for me to give it 5 stars for now, but I found no fault with it.

I flushed the water to empty the tank. I used a small wire to hold the part up that lets the water back into the tank. Once the water emptied out I remove the old leaky flapper and this new flapper fit on the prongs first try. I found the chain was a bit long. I did not want to cut it and make a irreversible error in judgement. So I simply put a loop on the hook and after two tries I said "Senior Girl Power, I did it"

The adjustable setting gradually changes over a few days & required a readjustment to restore the full flush. When removing the unit to make this change, the right side ear broke off. Apparently exposure to a week of cold Texas Panhandle water temperatures was more than the ear could take. Repair was not possible, unit discarded. Replaced it with a lower cost, non-adjustable Fluidmaster flapper which works fine & is more flexible.

I have used the Korky flappers for several years and constantly experienced it hanging open and not closing. Well, this time I spent about $6 including tax and purchased this flapper. It is simple and works perfectly! It never hangs and is designed such that it can't hang open. Great product and super price.

Rated 1 out of 5 by from Unhappy The chain keeps sticking to itself causing the flap to remain open and the toilet to run, which completely defeats the purpose of why I bought this in the first place. I would return it but have already thrown away the packaging. I prefer zero stars but the app doesn't allow that option.
