Most of my writing is about websites and software, but I also love good tools, equipment, computer hardware.
I have a leaky toilet tank flow valve, that controls when to turn off the water when you flush. My friend who frequently repairs houses, likes the Korky fill valves better than FluidMaster, because of the ease of installing them. To set the height of the valve in the tank, you simply turn the stem, pull it to the correct height, and lock the height by turning the opposite direction. They work well, last long, and are inexpensive.
You probably want to replace the flapper, the plastic that covers where the water flows from the tank into the toilet bowl, each time you replace the flow valve. You’ll also replace the flapper if the tank leaks; if you listen carefully you may hear a little water flowing, or put a few drops of food coloring in the tank and see if it appears in the bowl without flushing.
If you just need the fill valve, you can buy it separately.
