there was a thread here a few months ago and folks voiced their experience/s w/FluidMaster valve kits. some loved them, some hated them (including me) because of a short life.
today i got a letter from them, responding to a "survey" i submitted that included my comments about the short life. they blame it on "Tejas" water(!), too many chloramines and chlorine, and say two years is a very good result for Texas. i am getting 18mos or less.
this is a big state but most municipal water is surface, so this makes some sense to me, but i almost never smell chlorine in the water, maybe once or twice in the past 10yrs. i test water for my aquarium and it never registers chlorine strait out of the tap.
anyhoo, the letter said they are sending two 400a valve kits as thanks for the feedback. just fyi, --Loren
