Topics & Questions Best toilet fill valve
Is Fluidmaster or Korky better?
The Korky gaskets material was very pliant and strong but I feel better than the Fluidmaster. Unlike replacement flush valve gasket sizes, there is also a larger range of sizes. Two inches are probably the most common. A couple of newer bathroom models use three inch valve….
How long should a toilet fill valve last?
Toilet valves usually last about five to seven years and sometimes more if they are not maintained properly. Eventually, a fill valve can clog or leak.
