I didn't consider this unit to be noisy - actually quieter than the model that replaced it and didn't cause water hammer at shut off like the new one. The problem with that one is the problematic Leak Sentry system and that's the reason I got rid of it.

Fluidmaster400LS Rp4 Fill Valve, for Use with Most Toilet Tanks Including 1.6 Gal Models, Black, Pack of 1

Fluidmaster400LS Rp4 Fill Valve, for Use with Most Toilet Tanks Including 1.6 Gal Models, Black, Pack of 1

Q: It says American made and orgin of China. Which is it?

There is no origin on any component or the instructions but the bottom of the box says "assembled in Mexico".

Q: To make this short, one of my Fluidmasters decided not to work one day. Refill would not shut off; had to keep the tank lid off and move the float va

Check for some dirt or other foreign material in the valve and float. Also make sure that the float height adjustment is set correctly so that it shuts off below the top of the bowl fill tube. Otherwise the water cannot get high enough for the float to turn off the valve.

Q: Does this work on most toilets, even if their original system was not this brand?

Yes it does, it is a universal fill valve that will replace many of the older types of toilet valves
