    • High performance toilet fill valve
Size: Universal, for 2 In.
I recently upgraded to the Fluidmaster K-400H-039 High Performance Toilet Fill Valve, and I couldn't be more pleased with its performance! This product has made a noticeable difference in the efficiency and functionality of my toilet. Installation was a breeze! The instructions were clear, and I had it set up in under 30 minutes without any need for professional help. The adjustable height feature is fantastic, allowing it to fit perfectly in my toilet tank without any hassle. What I love most about this fill valve is its quiet operation. Unlike some other models I've used in the past, this one fills the tank quickly and efficiently without the loud noises that can be disruptive. It's a significant improvement in my bathroom environment. Additionally, the valve has a powerful flush, ensuring that my toilet is filled effectively after each use. The anti-siphon feature adds an extra layer of security, preventing any backflow and ensuring clean water supply. The quality of the materials used is evident; it feels sturdy and durable, promising longevity. I've had it installed for a few weeks now, and everything is still functioning perfectly without any leaks or issues. Overall, I highly recommend the Fluidmaster K-400H-039 High Performance Toilet Fill Valve to anyone looking to upgrade their toilet's performance. It's efficient, quiet, and easy to install, making it a fantastic choice for any homeowner. This product has truly transformed my toilet experience! ... show more

    • Quick, Simple Installation. Flawless, Silent Performance.
Size: Universal, for 2 In.
Changing out a toilet tank float is never my favorite project. When it became necessary, this item installed simply and flawlessly. The necessary level adjustment took only seconds. Installation took only a few minutes and it has performed perfectly and silently for months. I could not be happier

    • Easy even for an old lady
Size: Universal, for 2 In.
The toilet valve and flapper were quick and easy to install, even for this senior citizen woman. It works just fine and the flapper makes a good seal. It does seem very slightly noisier than the old valve but not enough to bother me.

    • Just what I needed!
Size: Universal, for 2 In.
10/10 I do recommend. It was pretty straightforward with installation. I did it myself. It felt durable. My toilet wasn’t filling with water & was also leaking water into the bowl. I changed this piece out & both problems were solved 🩵
