10 Best Toilet Repair Kits 2025 in the United States

The Kohler Genuine Part GP1083167 Silent Fill Valve Kit is designed specifically for Kohler Class 5 toilets, making it a great option if you need to repair or replace the fill valve in these models. One of its standout strengths is the silent fill technology, which ensures your toilet fills quietly, adding comfort to your bathroom experience. It includes adjustable fill-rate inserts, allowing you to optimize water usage, which is not only eco-friendly but can also help reduce your water bill.

In terms of installation, many users find it straightforward, especially since it’s designed to fit seamlessly with Kohler toilets. However, it’s important to confirm the shank color of your current valve—black means this part is suitable, while grey indicates you need a different part. This could be a bit confusing for those unfamiliar with plumbing parts.

Durability is another plus, as the kit is engineered by Kohler to maintain the original performance of your toilet, promoting longevity of use. The material is primarily plastic, which can be a concern for some buyers who prefer metal components for their sturdiness. If you own a Kohler Class 5 toilet and are seeking a reliable, quiet fill valve, this kit is a strong candidate. However, if you're looking for a more universal or metal option, you might want to explore other products.

The KOHLER Silent Fill Toilet Valve Kit (GP1138930) is a genuine replacement part designed to work seamlessly with Kohler Class 5 toilets. One of the standout features is its Silent Fill Technology, which ensures that the toilet tank fills quietly, providing a more pleasant experience.

The kit includes multiple fill-rate inserts that allow users to adjust the valve for optimal performance and water conservation, making it a water-efficient choice. However, it is crucial to confirm the shank color of your current setup to ensure compatibility—this part suits grey shanks, while black shanks require a different one (GP1083167).

The kit is relatively easy to install, even for those who may not be particularly handy, and its plastic and metal construction suggests reasonable durability. It does a good job of meeting the basic needs for toilet repairs, and it's worth noting that the cap color may vary and the surfaces should not be cleaned with abrasive materials to avoid damage. This KOHLER kit offers a practical and efficient solution for those needing to repair or upgrade their toilet’s fill valve system.
