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!

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.

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.

it works
A bit pricey but does the job. Perfect fit as a replacement for the one that failed.

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.

Great fit for older toilet
Easy to install. Took less than 30 minutes with no previous experience. Changing the fill amount was a little harder but no issues.

A great flush valve!
Like many others, I needed to replace a few gaskets on my Aquasource T801 toilets due to the use of chlorine tablets in my tanks; but found factory replacement parts virtually impossible to locate. I found it better to just replace the entire flush valve with a known major brand like fluidmaster so that way I could locate any parts if needed in the future. While I had the tanks fully drained, I also took the opportunity to replace my fill valves, push buttons, and tank to bowl bolts plus gasket; all with fluidmaster parts. Both toilets are working even better than they did with the original parts and I now have peace of mind. Installation of all components took about 1 hour for each toilet. Overall, I'm happy with the fluidmaster parts; they seem very durable and I hope they last for a very long time. BTW don't drop chlorine tablets directly in your tanks if you expect your new parts to last! Fluidmaster also makes a tablet cleaning system which protects all of the rubber gaskets and seals which I've also installed in my toilets now.

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.

Perfect replacement for my broken dual flush toilet

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.
