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.

    Took 15 minutes to pull the old one out, install the new parts and fine tune. The only tool I needed was an adjustable wrench to loosen the old nut. Works great and the instructions are really good, plenty of pics and info on adjusting the tank water height and bowl water height. Don’t over tighten the nut! Hand tight then add a half turn!

    5.0 out of 5 stars Good quality and full flushing control

    D.H. · August 8, 2025

    Easy to install and very adjustable to increase flushing power and/or toilet water height. Inexpensive but the plastic is durable enough to hold up for years.I’ve installed this same model in numerous toilets and have never worried about their quality.

    Simple to install, making this an easy fix... I wish there was a better way to adjust the height of the float to fit the tank.

    Fluidmaster toilet valve refill has a long history of offering a good product at a reasonable price for the "do it yourselfer." Once installed they work perfectly with no running. Now, there is one thing I need to caution you about. These kits have different sizes on the toilet flapper so please make sure you order a kit with the right size flapper. Unfortunately, I was not aware of there being different size flappers I had to make a quick run to a box hardware store to get the right size flapper. Otherwise, no leakage, quality, water saver, and durability all in one unit.

    5.0 out of 5 stars Great Product!

    When you need to fix a leaky toilet, you want something that works the first time you install, this is it, pretty easy install, just make sure you get everything tightened up after, Great Product!

    5.0 out of 5 stars These are good replacement fill valve kits. Anyone can do this replacement

    Fluidmaster K-400H-039 High Performance Toilet Fill Valve with 2-Inch Adjustable Toilet Flapper Kit arrived as pictured and described with no surprises, thank you. These are good replacement fill valve kits. This one ha a flapper specifically for the 2" diameter tube. If you're not sure which kit you need to order, simply measure your pipe diameter under the flapper valve in your toilet with a measuring tape. It'll either be 2" or 3" in diameter. These are easy to install and the included hardware does not require any tools for installation. You simply tighten the connections by hand with your hand. You can easily adjust the water level in the tank up or down without any tools required as well. These last very well. My area has very hard water and is prone to calcium/lime buildup so I usually get around 5 years out of these valves. Which reminds me, while you're doing this replacement it's a great time to pour in some vinegar to your tank and the tank drain to keep everything working as it should. The vinegar will safely dissolve/remove any calcium/lime buildup from the tank and the bowl drain area (this also cures slow flushing toilets due to calcium/lime deposits). And it's only a few bucks per gallon. Anyone can do this replacement, if you're a first timer, watch a few videos before you begin and you'll ace the install like a pro.
