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

Nice replacement flapper

Fits my Rosario just fine!

Excellent works as intended

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

The only one that fits old Kohler. Works like a charm.I’m installed it on a Kohler K3434bb and it fits perfectly.

STOPPING "RUN-ON" IN YOUR OLDER 1-PIECE KOHLER TOILET1>> 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. Tubef> 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 1B1Xa> Turn the water to the toilet back on.5>> If #1-#4 do not solve the problem thena> 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.IMPORTANTCompare 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 NOTEEven 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.
