When your toilet starts running constantly, it’s usually because the refill tube that sends water into the bowl is leaking. You can easily replace the tube yourself in just a few minutes.
The toilet refill tube is a tube that goes from the water supply line to the fill valve in the toilet tank. It is used to fill the toilet tank with water.

What is the purpose of the refill tube in a toilet?
The overflow tube is an important part of a toilet’s design. It helps to prevent water in the tank from overflowing into the bowl in the event that the ballcock (a device that controls the flow of water into the tank) malfunctions.
To remove the old water assembly, unscrew the mounting nut with an adjustable wrench.
Does a toilet need a refill tube
The refill tube is an integral part of the system, as it tells the overflow tube how much water to input into the bowl. Without a properly functioning refill tube, the toilet bowl will either have no water, or overflow with too much water. A properly functioning refill tube is essential for a toilet that flushes properly.
If your refill tube is too long, you may need to shorten it in order to stop your toilet from running constantly. To do this, simply cut the tube to the desired length with a sharp knife or scissors. Be sure to measure the tube before cutting, so that you don’t cut it too short!
Does toilet refill tube go into the overflow tube?
The Refill Tube must be located above the Overflow Tube. If it’s pushed down into the Overflow Tube, it can siphon water from the tank into the bowl causing the Fill Valve to cycle on and off.
To install a new overflow tube and flapper assembly:
1. Grab the new overflow tube and flapper assembly from your kit.
2. Insert the new overflow tube back into the toilet tank.
3. Make sure it is sitting flush against the bottom of the tank (you may need to tilt the tank for it to feed all the way through).
4. Set your level up to the line indicated on the fill valve.
How do I know if my fill tube is damaged?
If you’re hearing constant running water from your tank or your flush isn’t powerful, there’s a good chance your fill valve is bad. You can test this by adding a few drops of food coloring to your tank. If the food coloring doesn’t leak into the bowl, you’ll need to replace the fill valve.
The flapper is a small rubber or plastic disk that covers the hole at the bottom of the tank. It’s connected to the handle with a chain or rod. When you lift the handle, the flapper lifts and water flows from the tank into the bowl. The flapper regulates the amount of water that passes from the tank into your bowl during the flush cycle. The refill tube is the small plastic tube that’s connected near the top of the ballcock mechanism on one end and to the inside of the overflow tube on the other end. The refill tube allows water to flow from the tank into the bowl to refill it after the flush.
Can I replace a toilet fill valve myself
If you have a little spare time and feel confident following instructions, hiring a plumber may not even be necessary. Toilet fill valves are replaceable parts, so fixing a broken valve is a matter of opening the toilet tank, taking out the damaged part and putting a new one in its place.
If you begin to notice strange sounds coming from your toilet, it is likely that the fill valve is beginning to deteriorate. A broken fill valve will allow too much water to enter the tank, which will increase the amount of water that is sent down the drain with each flush. To avoid this, it is important to regularly check your fill valve and replace it if it is broken or damaged.
How often should you replace toilet fill valve?
The fill valve is a vital part of your toilet, and it’s important to replace it every five years or so. The fill valve is constantly exposed to water, so clogs or leaks are inevitable, and the assembly itself usually lasts about five years. By replacing the fill valve regularly, you can keep your toilet in good working order and avoid any potential problems.
To unthread the mounting nut from the fill valve shank, disconnect the refill hose from the fill valve, and remove the fill valve from the tank, you will need a Phillips screwdriver and a wrench.
How do I stop my toilet from running randomly
If you turn the adjustment screw clockwise it will raise the water level.
If your toilet is running constantly, the issue is most likely with the flapper. The flapper is the rubber seal between the tank and the bowl and when it’s worn, water can seep into the bowl. This will cause the fill valve to cycle on as soon as the float falls below the cutoff level. To fix this, you’ll need to replace the flapper.
How do I stop my toilet from running intermittently?
If your toilet keeps running or runs intermittently, it may be because you’re not getting a good seal. Try a different flapper if the toilet won’t stop running. If you just can’t find a flapper that seals, consider replacing the entire toilet overflow tube/flapper. On most toilets (two-piece), this means removing the tank.
If your boiler’s overflow pipe is leaking water, it may be due to one of two things: either the boiler has built up too much pressure due to the expansion vessel failing or losing its charge, or the pressure relief valve is not seated correctly, causing water to pass by it. If you suspect either of these issues, you should call a qualified technician to come and take a look at your boiler.
What does a broken fill valve sound like
A toilet making an air noise or a whistling or hissing sound is a sign that the fill valve is not closing and sealing properly, and air or water is leaking from the fill valve. If the fill valve isn’t closing properly, begin by replacing it. If this doesn’t solve your problem, call a plumbing professional.
The fill valve is located at the back of the toilet. To remove it, simply unscrew the retaining nuts and lift it out.
Are toilet fill valves universal
Most toilet fill valves are compatible with other valves of the same type. For example, a universal float cup valve will usually fit the tanks of most toilets brands that contain a similar valve. This makes it easy to find a replacement valve if you need one.
The supply line for a toilet typically measures 3/8” in diameter, but the length can vary from 9” to 20”. Make sure to measure accurately to ensure you are buying a part that will match your installation.
What is the black tube in toilet tank
A fill tube is a small plastic hose that is normally clear or black in color. It connects to a vertical plastic tube which is known as the overflow tube. This is all contained within the toilet tank. A damaged orbroken fill tube is one of the most common problems we see with toilets.
The flush valve is the large, round valve located at the bottom of the toilet tank. If the hole in the bottom of the tank is about the size of an orange or baseball, you need a 2-inch seal. If the hole is more like the size of a grapefruit or softball, you will need a jumbo 3-inch seal.

A toilet refill tube is a flexible tube that is used to refill the tank of a toilet with water.
Without a toilet refill tube, your toilet will not function properly. This tube is responsible for bringing fresh water into the bowl so that you can flush your waste away. If your toilet is not flushing properly, it is likely because the refill tube is not working correctly.
