Review: Works Great..After Solving the Problem! - My Kohler is a K4634 and after 20 years of faithful service I replaced all the parts. The steel plate, seals and the Kohler canister upgrade and new water fill valve. Everything was easy to replace..the original flapper set up not so much. I couldn't get the big plastic nut on the bottom of the tank to move so I took it apart in pieces on the work bench with a screwdriver/chisel and hammer. Don't try it in the bathroom. After adjusting the fill valve and a test flush I was back in business with a quieter, upgraded toilet. Problem was inconsistent flushes. Fluids poor to ok flush, solids very disappointing. Weak water pressure and loud bubbling noises. Sometimes two flushes were required. Now think fluid dynamics, the fix is easy. If you take a full gallon jug, turn it upside down to empty it you get an air lock. Same thing happening in the tank. The fix; 3 inches of duct tape, cut in half length wise. Put two layers of tape on the top of left or right side of the tank under the cover. No more air lock and a power flush every time. Review: works great - always check the toilet brand Once I did that it fits perfectly ,works great ## Features - 3" Toilet Canister Flush Valve Kit: Features a 3" canister with a 3" outlet - Identification: Look inside the back wall of the toilet tank to identify tank model number - Compatible with Kohler Cimarron tank model number K-4634.

Tube had hardened after 8 years of use. When replaced tubing, I found the 1059289 Canister Flush Valve Stop Kit (the plastic piece to which the tubing attaches) had cracked, no longer able to twist lock. I will either replace it (original black plastic piece is discontinued - 'appears' to be replaced by flush-valve-repair-kit-1229656 with larger yellow plastic piece) or drill a hole and insert a pin to hold it in place. The teflon tape idea or some 'reversibly' applied rubber cement, might be needed to hold tubing in the valve stop item. **Q: how do I install kohler 1083980?** A: In a nutshell, the lower two components in the image go under the tank and everything else goes inside. If you can't use the installation being replaced as a guide for installing the new one, this site (http://www.plumbingsupply.com/kohlertoiletparts-cimarron.html) also kind of helps visualize how it all fits together with the tank plate. **Q: where do i find toilet model number/** A: On back of toilet tank- you will have to remove it to see it **Q: Will this flush valve fit the 1.6 Gal model?** A: I replaced the flapper (old style) Kohler pn:1024385 with this canister upgrade and while it does work, my wife & I both agreed that old style provides stronger flushing, don't recommend if you want to retain original powerful flushing. Nowhere in documents do I find if this new style was to try conserving water, but suspect it might be part of new design. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great..After Solving the Problem! *by D***B on June 21, 2022* My Kohler is a K4634 and after 20 years of faithful service I replaced all the parts.
