4 Common Causes & Solutions for Your Jacuzzi Dual flush toilet Keeps Running

In this chapter, we will break down the reasons behind a faulty dual-flush toilet and the way of getting rid of them. 

1. Flapper Gets Worn Out

Whether you have a normal or dual-flush toilet, a defective flapper or toilet seal is the main culprit behind a malfunctioning toilet. The rubber tube may get worn or out of alignment over time. 

You can follow the below steps to check for a faulty or worn-out toilet flapper. 

  • Start with shutting off the water flow to the toilet tank and flush your toilet to remove every single drop of water.
  • You can use a towel or sponge to pick up the remaining water.
  • Locate the toilet seal by removing the flush valve canister and check for the crack. 
  • If you find the flapper gets worn out, you must replace it with a new one. 

Solution: Replace the Flapper

Replacing a toilet flapper is not rocket science. Just follow the step-by-step guide below to change the cracked seal. 

  • Shut the water supply off to your toilet tank by turning the shutoff valve dial clockwise.
  • Flush your toilet to empty the tank and use a towel to sponge out the remaining water.
  • Detach the worn-out flapper valve by unclipping the chain. Then, remove the flapper by pulling out the flapper edges.
  • Purchase a new toilet flapper or flush valve seal
  • Attach the newly flapper to the toilet flush valve
  • Customize the chain length
  • Test your new flapper

2. Defective Float Cup

You can also find a float cup attached to the body of your toilet fill valve. Generally, the float cup connected both the toilet tank and the waterline. The mechanism of this element is to fill your toilet tank with water. 

If it gets damaged or broken, it comes up and sets its height to a higher position. Consequently, the fill valve starts filling your toilet tank with water continually. And you know the overflowed water runs down to the bowl. 

Solution: Replace the float cup

Here is the step-by-step method of changing the float cup valve. 

  • Shut off the water flow to your toilet tank and drain it.
  • Remove the hose out of the top and then screw off the washer.
  • Lift your cup valve and twist to the side to remove the handle, and you can find the cup valve. 
  • Now, you can find a gasket at the bottom. So, reach down there and use your hand to pull it out. If the gasket is worn out, you should get a new one from your local market. 
  • Get a float valve cup and also a new gasket. 
  • Put the gasket back into its place first. Afterward, take your new cup valve and keep it over the gasket. 
  • Reattach the top washer. Finally, put the hose back into the top.

3. Clogged Fill Valve

Dirt or debris may enter your toilet and make the fill valve clogged. Therefore, sometimes dirty water also causes your toilet fill valve to be blocked. In this case, prevent water from flowing to your toilet tank and pull the lid out from the fill valve. Then, check whether there is any debris or dirt that clogs up your toilet valve.

Solution: Clean the Fill Valve

To get rid of this problem, just remove the debris from the fill valve. You can also use a brush to pick away dust. Once you clean the valve, test to see whether the problem is solved or not by recapping the fill valve.

4. Broken Zip Tie

Every dual-flush toilet, like Jacuzzi, features a zip tie to hold the base of your toilet valve in its place. If the valve wobbles around or doesn’t stay in its position, your dual-flush toilet keeps running. Sometimes the zip tie may break down before the entire assembly.

Solution: Replace the Zip Tie

The only way to solve this problem is to replace the damaged or cracked zip tie with a new one. It will be better if you can change and place two zip ties to ensure the base of your fill valve won’t wobble.
