American for the win

Korky's enclosed floater doesn't get stuck/snagged as easily as Fluidmaster's. Height adjustment is also a bit easier with Korky. I will admit that Fluidmaster seemed to fill a little bit faster and a little quieter, but I prefer Korky's better reliability and simpler installation. And Korky's is Made in the USA at a very competitive price!

Easy installation perfect fit.

the fill valve was very easy to install. directions were easy to follow and it only took about 15 minutes to install. I did not need any tools for the installation on my particular unit. everything is just hand tightened down and work perfectly and is very quiet.

Very easy to assemble so many I keep getting. This is the 3rd one I have purchased. Not due to problems but bc I have had such good results with. 1 was a different house. others were to replace others (older model) and one was several years old @5 probably had more life in it but had to change another part so decided to change it as well. It is a little tricky to get the "right fill setting " to make sure it doesnt let out to much or too little water. I always have to check instructions for the little metal thingy to see how it goes. But very easy less than 10 mins to install. I like that I can do it myself instead of paying a professional to do it
