Review: 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!
Review: 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.
