I have an American Standard toilet from 1985. Inside the tank it reads 4083 and M-3A. I have replaced the valve and flapper assembly 3 times in about 20 yrs. I last replaced the flapper kit less than a year ago. Eventually, these assemblies become unreliable and the toilet begins to run after every 2 or 3 flushes. Sometimes the chain attached to the flapper gets kinked and other times the metal flush handle itself just catches. Jiggling the handle will correct either problem but I don't always know it's running until sometime later.
Is there a flapper kit you can recommend that is somewhat trouble free?
