Title: You will be replacing this annually!
Review: I made the big mistake of replacing a couple of toilets in my house with Briggs 4400's. They use the Fluidmaster 400 tank fill valve and I have problems with them every single year. I have city water that is a little hard and it causes the black float to bind on the gray tube after about 1 - 1.5 years. I have tried cleaning the parts but you can't clean inside the hole of the black float. So every year or so I have to replace the thing. Fun.
