It includes a fill valve, flush valve, gasket, hardware, tools, clip, and locknut, which means you have all the necessary components in one package. This can save time and effort as you don’t need to make multiple trips to the store.

The kit is compatible with most toilets that have a 2-inch outlet connection, making it a versatile choice for many users. The materials used are primarily plastic, which is lightweight and can be durable, but some users might prefer metal components for certain parts for added robustness. Installation is designed to be user-friendly, catering to both amateur and professional users. However, if you are not comfortable with DIY repairs, you might still want to consider professional help.

The kit also adheres to Proposition 65, ensuring it meets safety standards. The ease of installation and included instructional components make it a good choice for those looking to handle toilet repairs themselves. Durability seems adequate for general usage, although long-term wear might be better handled by higher-end materials. The kit is also designed with water efficiency in mind, potentially helping to reduce water usage. However, this aspect can be influenced by the overall setup of your toilet. In summary, the Fluidmaster K-400H-021-P8 is a solid and convenient choice for those needing a quick and comprehensive toilet repair solution, particularly for those comfortable with handling basic home repairs.

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.

Another strong point is its durability, highlighted by the use of stainless steel hardware and a 7-year warranty, which suggests a long-lasting performance.

Additionally, the PerforMAX fill valve is engineered for fast and quiet refill, with adjustable features that allow for customized water usage, promoting water efficiency. However, some users might find the adjustable components a bit tricky to fine-tune, particularly if they are not familiar with toilet mechanics. Despite this, the ease of installation and comprehensive nature of the kit generally make it a convenient choice for most homeowners looking to repair their toilet without needing professional help.
