Work well with hyper tough flush value

This item works well with the hyper tough flush value. I replace the green flapper because I didn't want to go through the trouble taking off the flapper and adjusting it with a screw driver With the fluid master universal flapper, you can easily adjust the flapper with your hand while fill valve is filling the toilet. Start with 5 because if you start 9, water will come out from under the toilet. This means too much water is being used. The extra water got no way to go so it just comes out under the toilet. Keep adjusting until your toilet flush properly and make sure no water coming from under the toilet. If it doesn't flush properly at 5, that means you need more water. Go one number at a time until it right If does flush properly, you can try go to with less water and see what happens. The more water you save the better I guess. I am no plumber this is just base on my experience working on my two toilets and what I read online .

Love the new Fluidmaster adjustable water flapper

This Fluidmaster 2" flapper replaced my 15 year old leaky Fluidmaster flapper. The new one seemed improved and was easy to replace by following the simple directions on back of package. I noticed that my old flapper was set on the max level, so I set the new one on 6 and my American Standard toilet flushes easier than ever since a plumber replaced my original toilet and he also installed the kit and flapper inside tank, me never aware of that it was an adjustable flapper. I'm very happy with purchase at Walmart.com. I purchased on sale, it arrived at my front porch the next day via free delivery by Walmart. No more running water noise every 20min lasting for 10 seconds. I saved money by doing this myself.

Great money saver

I was not aware my old flapper had stopped working until I got my water bill and it was 2 times the normal amount had my neighbor check and ordered this item. Needless to say my next bill was back to normal This is an awesome product and has continued to work well these past months. Thank yo for offering this item but mostly for all the dollars saved
