10 Best Toilet Repair Kits 2025 in the United States

The Kohler Genuine Part 1083980 Flush Valve Kit is specifically designed for Kohler Cimarron toilets, making it a solid choice if you have this model. Its 3-inch canister size matches the original parts, which helps ensure a good fit and proper function. Since it’s an official Kohler part, compatibility is reliable, and you can identify if it suits your toilet by checking the model number inside the tank.

The kit includes the flush valve itself but no extra components like gaskets or bolts, so you might need additional parts depending on your repair. Installation is fairly straightforward for someone comfortable with basic toilet repair steps, as it’s made to slot in place of the original valve. The plastic material is standard for these parts—it’s durable enough for regular use but may not last as long as metal alternatives in very heavy-use situations.

Water efficiency remains in line with the original toilet design, so it won’t improve or reduce water use but will maintain proper flushing performance. This kit suits homeowners or DIYers with Kohler Cimarron toilets looking for a dependable replacement flush valve. If you have a different toilet brand or model, this kit won’t be compatible. Also, if you prefer a kit with more installation accessories included, you might want to look for a more comprehensive set.
