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.

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!

Works well. Easy to replace
This was basically the exact replacement for the valve that came in the tank of a Glacier Bay two-button toilet. The upper part of the valve is the actual flush mechanism, and the bottom part attaches to the tank. Since it was the same part, I was able to separate the flush valve from the lower fitting and did not have to remove the tank. The upper flush valve connects to the lower part bayonet style. About a quarter twist, and they separate. Since there was nothing wrong with the lower part, I simply replaced just the flush valve. Only took a few minutes.

Exact replacement for my Glacier Bay toilet
A perfect fit for my Glacier Bay toilet, which had this exact flush valve in it from the factory. Installation is easy if you have moderate mechanical skills.

Replaces Glacier Bay N2316 Flush Valve
It's very difficult to find and source the proper OEM flush valve gasket for Glacier Bay toilet N2316. Rather than deal with that every time it needed replacing (the toilet in question isn't near anywhere we were likely to find the part) we opted to switch to this easily found Fluidmaster flush valve. In the process we found out that most of this model toilet produced after we bought ours (over 7 years ago) now use the Fluidmaster valve as original equipment. Fluidmasters instructions are great, the illustrations are helpful, and the parts fit properly. Pretty much anyone with the strength to lift the toilet tank from the bowl (it's NOT very heavy) should be completely able to handle removing the old valve and replacing it with this one. Just follow the instructions carefully. Only basic hand tools are needed. The only "difficult" part is sizing the included actuator rods for the new valve. Take your time and that will go fine as well. Installation went so easily that we purchased a second valve shortly afterward for when the other Glacier Bay toilet in this house needs the same maintenance.

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.

Would Recommend but Check all parts are there
Had to return product I received from Amazon since the product was missing the rubber valve that releases the water to flush hence the missing 1 star. Bought the exact product at local store and it works perfectly.
