KO-83064 GENUINE PART GP83064 FLAPPER FOR SELECT ONE-PIECE TOILETS

perfect fit! Toilet works great now no mor leaking.

Doesn't work so great if you end up ordering the incorrect part. Don't simply rely on the toilet's model name and number. Kohler is known for switching up the internals in their toilets and only adding minor revision indicators (aa, bb, cc, etc). You need to compare the part to be replaced with this photo. What you don't see in this photo is an opening at the bottom with a white styrofoam disk inside the flapper. The original part may also be made of black rubber, as was the first one I replaced (and that material was rotting/flaking after about 5 years while the red ones have hardened/discolored but didn't flake off). Look for the same shape. This is the perfect replacement part if it matches the part to be replaced. It works great if selected correctly, where it should fit perfectly. Nothing should have to stretch or be pulled. The arms will sit somewhat loose and the rubber should mate nicely with the valve surface. If it doesn't fit perfectly, then the wrong part was ordered. I will put out that there are also functionally equivalent aftermarket parts from Fluidmaster and Lavelle/Korky, and both have been suppliers of Kohler flappers at one time or another.

Just the part I needed for my Kohler toilet.

Perfect fit, Chai very light and floats up to and some times slides out of hole. S hook needs to be crimped. Need to adjust chain slack to a minimum to prevent tangle and slipping off flush arm

Perfect fit for our older Kohler low profile toilets. Installation is super easy and these seem to last at least a few years with daily use.

STOPPING "RUN-ON" IN YOUR OLDER 1-PIECE KOHLER TOILET 1>> Turn the screw in the center of the top of the balcock mechanism ¼ turn to the right. > Repeat as necessary, but don't be too quick to repeat. Give it a chance to work. > The effect is to lower water level of the reservoir. I don't know why this reduces run-on. A toilet may work fine for 6 months and start running, which is fixed by a 1/4-turn, then it's fine for another year. Sometimes it may take as much as full turn (in 1/4-turn increments over a week's time) to completely stop the running on. 2>> If #1 does not solve the problem then: a> Turn off the water to the toilet. b> Remove the float. c> Remove the flapper and clean* it thoroughly with a cotton cloth. d> Clean* the seat of the flapper (in the toilet) with a cotton cloth. If you have very hard water, you may have calcium deposits on the seat which are not easily removed by rubbing. Use a cloth soaked in vinegar, or a product such as "lime-away" to clean off calcium deposits. e> Coat the flapper and the seat with a thin layer of silicon grease**. Permatex 22058 Dielectric Tune-Up Grease, 3 oz. Tube f> Reinstall the flapper and the float, turn the water back on. Even if #1 and/or #2 fixes the problem, you should still perform #3-4 while you are working on the toilet--You've already done half the work, and it takes only a few more minutes. 3>> Remove, clean*, grease**, and re-install the ballcock plunger and (o-ring) gasket. 4>> If the cover ("top assembly") of the ballcock mechanism is broken or cracked, then replace. Lasco 04-7175 Toilet Ballcock Repair Top Assembly for Coast Brand 1B1X a> Turn the water to the toilet back on. 5>> If #1-#4 do not solve the problem then a> Replace the flapper (including greasing** it). b> Replace the plunger and (o-ring) gasket (including greasing** them). Lasco 04-7183 Toilet Ballcock Repair Kit with Plunger and Gasket for Coast Brand 1B1X . See my instructions under that product, particularly for how to adjust the screw in the top of the balcock mechanism. IMPORTANT Compare the Amazon photos with the parts of your toilet to be certain that you are ordering the right parts. * "Clean" generally means to rub with a cotton cloth (not just a paper towel) until no more black comes off onto the cloth. You can use a little soap if that helps. **DO NOT use petroleum grease (or "petroleum jelly"), it will rot rubber parts. Really. Seriously, DO NOT use petroleum grease. GENERAL NOTE Even when you've done all these things, you may experience intermittent slow "running" of your toilet. Don't panic. > It can take a week or longer for the new components to "settle in". Excess silicon grease can cause components to be "sticky" for a few days. So be patient. > If the running is significant, try #1, repeat as necessary. If still a problem, tighten the 3 cover ("top assembly") screws (see my instructions under that product) > This toilet will run a little intermittently under the best of circumstances. So don't be panicked by an intermittent very light flow. > Click on “Stoney” just below the product title to see my other reviews, or leave a comment to ask a question.

Easily installed in less than a minute... both of my toilets now operate perfectly with a very solid flapper seal and absolutely no leaks. This OEM Kohler flapper #83064 works if you have an earlier Kohler Rialto with a square drainage box and metal side lugs. I called Kohler direct to confirm. Apparently some later model Rialto toilets have a different drainage box (plastic and rounded) that requires a different type of Kohler flapper - you cannot always rely on the pictures shown on the back of the package - call Kohler if you are not sure.

I searched the web and found I need GP83064. As soon as I receive the flap, it obviously doesn't fit. Then I noticed this flap work with a square overflow pipe. Mine is a round pipe. I went to local home depot, bought a Kohler GP49114 and it perfectly fit. Should have gone to local home depot in the first place. Any way, the parts list on the web is not always reliable. Since this is not what I want, I have no idea whether this work or not, give it 3 stars in the middle.

Satisfied. Problem solved.

All good.

Good for older kolher toilets

Parfait

Works and fits as advertised.
