Review on Water-Saving Toilet Flapper Compatible with TOTO Flapper Model THU140S - Long Lasting Rubber Seal, 3-Inch Replacement - Includes Stainless Steel Chain and Hook - Easy Installation (Pack of 1, Blue) by Anthony Boylan

This toilet seat worked much better than the universal seat I first installed on my Toto toilet which kept leaking water. However, unlike the original damper that has served us well for 16 years, this damper requires a gentle touch to achieve full flushing. If you either press too gently or hold the pin for too long, not enough water will flow to completely flush out the solids or toilet paper. As a result, you'll need to do a few resets to get everything right.
