Review on Danco FLT231T Black Toilet Tank 🚽 Flapper Replacement – An Optimized Alternative Solution by Mark Allen

I like the concept of eliminating the unreliable flush levers that raise the shock; no chain to get stuck under the shutter, no lever to rust, bend, etc. However, after installing some of them, they all leak; It is enough that you cannot easily notice it. I filled the tank, shut off the water in the tank and the next day checked the water level in the tank and they are all leaking. I think the problem is how it attaches to the overflow pipe. To secure the clamp to the overflow pipe, a zip tie is supplied to hold the valve in place. Since the plastic clip is on one side of the valve, I think the pressure from the clips is enough to slightly "tilt" the black rubber gasket that sits over the toilet tank drain, allowing a small amount of leakage between the rubber gasket and allows drainage. Hole. NOW I can appreciate the wisdom of how the old rubber damper works. The weight of all this water evenly over the damper holds the damper tight against the drain. If there was a way to seal the danco tightly over the drain it would work, but I couldn't get it to work without leaking no matter how hard I squeezed the danco and tightened the zip tie. What a pity!
