45 minutes of searching and nothing yet. Toto drake eco version, about 2 years old. Tank is st743E, bowl is elongated and the handicapped version. fill valve says "e-max by toto" on top and is green.
Upon flush, the fill valve cycles on and off about once per second until the tank is full. Never did this before. Fill valve seems to work correctly except the cycling on and off. No leaking in between flushes.
Is this fill valve able to be disassembled and cleaned? With a fair amount of pulling, I cannot seem to get the top cover off. It seems to be one piece to me. Am I not holding my mouth right?
Thanks in advance for your time.
