The Cause of Leakage—Is It Really the Fill Valve?
A toilet leakage may be due to two main valve defects: a malfunctioning flush valve or a fill valve. There is a shank inside the flush tank, not attached to the float. That is the overflow tube. If water level is below the top of the tube, then the problem lies with the flush valve. If water is overflowing into the tube, then the toilet leak is due to fill valve malfunction. That being said if there is water leaking around the bowl, then it could be the toilet seal or even a constantly running toilet flapper.
What Exactly is a Toilet Fill Valve?
Fill valves, or ballcocks are devices that regulate water flow in your toilet. Traditional models have these valves attached to a float via a float arm, made of brass or plastic. The floats are empty ball-shaped structures, serving to open or close the fill valve according to the water level inside the tank. Flushing will empty the tank, causing the float to droop to the bottom.
This opens the fill valve and water enters the tank from the supply line attached to its base. When water level reaches a set height, the float that has risen with the water closes the fill valve, cutting off the water supply. This height can be adjusted in most modern fill valves. Thus the toilet is set for another round of flushing and the process repeats time after time after time. As you can see, it’s extremely important to have the best toilet fill valve so that this process runs smooth every single time.
Types of Fill Valves
- Plunger or Piston Type: These are the traditional ballcocks, almost exclusively made from brass. The lever principle outlined above raises or depresses a plunger in the valve, to allow water in or to cut off the supply.
- Diaphragm Type: These ballcocks, made either of brass or of plastic, functions similar to the plunger type. The main difference is a button replacing the plunger of the traditional type.
- Floatless Type: This is made out of plastic, and eliminates the use of ball and rod. A diaphragm at the tank’s bottom senses the pressure inside the tank and lets in water accordingly. It is great for low profile tanks because of it smaller size.
- Float Cup Type: These newer type valves were developed in the 1950’s with a float cup that moves along the fill valve shank. The cup’s height is determined by the placement of a spring clip connected to a pull rod that turns the valve on or off.

Korky vs Fluidmaster Fill Valves – Who Do I Prefer?
After doing a bit of research on toilet tank fill valves, you most likely have ran across the companies Korky and Fluidmaster. Both of these companies are pretty well known and respected in the plumbing industry. I have used both of these companies for a quite a few different toilets over the years, and to put it simply, you can’t go wrong with either of them. That being said, for everyone of my toilets at my house I actually prefer to use Fluidmaster valves. The reason being that I personally have had less Fluidmaster valves break than I have Korky. I will be completely honest, this could simply have been luck on my part, and it is really just personal preference. Korky makes great products that are durable, but after using Fluidmaster for so long, I find myself sticking with them! That being said, when you are looking for the best toilet valve, either of these companies are a great start!
