Excellent Quality Replacement Flush Valve
I installed this Fluidmaster 3-inch dual flush valve in my two-piece toilet, and the quality impressed me right away. The plastic feels sturdy and well made, not flimsy like some cheaper replacements. The instructions were easy to follow, and installation was straightforward with basic tools. After installation, the dual flush works smoothly, and the toilet seals properly without any leaks or phantom flushing. It restored the toilet to like-new performance and has been operating reliably. Overall, this is a solid replacement part with good build quality. If you have a compatible toilet and need to replace a worn-out flush valve, I would definitely recommend this product.

Perfect replacement for my Glazier Bay toilet
The unit was quite easy to install. I had no issues with the fit or operation of this item. I did not replace the tank bolts or the seal between the tank and the toilet base. As I should expected 20 year old seals are not the best. After a minor leak I replaced both the bolts and the seal and everything is great. I would recommend if you are changing this item to also do the bolts and seal.

Excellent Upgrade – Saves Water and Works Flawlessly!
I recently installed this dual flush valve in my toilet, and I couldn’t be happier. The installation was straightforward, and all the parts fit perfectly. The valve operates smoothly, giving a solid flush every time without any leaks or issues. The dual flush feature is fantastic – it’s easy to choose between a full flush and a half flush, which has noticeably reduced my water usage. The materials feel durable and high-quality, and it seems built to last. Overall, this is a reliable, eco-friendly upgrade for any bathroom. Highly recommend for anyone looking to save water and improve their toilet’s performance!
