Review on 🔧 Toto THU123 Replacement Valve Cap Assy: Top-Quality Solution for Optimal Performance by David Forleo

This Toto THU123 inflation valve cap is perfect for my Toto Drake 2 with ST743E01 tank. I have water in the tank through the drainpipe. The water has risen above the water level mark on the fill valve. I was looking to replace the entire inflation valve assembly but tried this THU123 valve cover. The replacement was a very easy job in 2 minutes. After installing a new valve cover the problem went away. Saved me time, the mess of emptying the tank, and the added expense of a valve fill assembly. Very happy with the result.
