Frequently Asked Questions

Where is the unit placed for the best performance?

The LeakAlertor can be placed anywhere along the rim of the toilet tank. More important than the location, is to make sure that the sensors do not touch each other or the side of the tank. Be sure the sensors are clear of any parts inside the tank such as the flapper, fill valve, etc. If the sensors are touching each other, the sides of the tank, or parts inside the toilet, gently bend the sensors away from the obstruction. The sensors do not take a lot of effort to bend. While making adjustments, support the sensors by holding the protective plastic tubing between your thumb and forefinger, and make adjustments with your other hand.

My LeakAlertor isn't flashing any lights when I flush the this right?

No. The LeakAlertor provides an indication during every flush, even if your toilet is functioning properly. (See the Alerts Chart). If no lights flash at any time during a flush, you can test the LeakAlertor by pressing the reset button. Hold the RESET button until the RED lamp flashes. The unit will then flash all three lamps at once and beep. The unit then flashes just the GREEN lamp one to two times per second for approximately one minute. When the RESET is completed and the YELLOW lamp flashes flush the toilet. If the unit does not flash at all, the battery probably needs to be replaced. (See Battery Replacement Instructions)

How loud is the LeakAlertor?

We describe the audible alert as being louder than the “chirp” you hear when your home’s smoke alarm battery is going bad, but quieter than when the smoke alarm is actually going off. You should be able to clearly hear the LeakAlertor from at least 30 feet away, even if the bathroom door is closed.

What are the wires sticking out of the LeakAlertor?

The wires are actually “sensors” that connect to the circuit board inside the LeakAlertor. As the water rises and falls along the length of the sensors, the LeakAlertor is able to calculate the rate of change of the water height. The proprietary software developed by our engineering team analyzes this information in order to determine if your toilet is leaking, constantly running, or is about to overflow.

A leak was what?

I just replaced my flapper - do I need to reset my LeakAlertor?

Yes, simply press the reset button.

I just replaced by flapper, and my LeakAlertor is still indicating a leak... why?

Once the reset operation is complete if the LeakAlertor is still indicating a problem, unfortunately you probably still have a leak. We suggest contacting a local plumber to find out the cause.

The RED lamp is flashing, but I used dye tablets and there is no coloring in the bowl... why did the LeakAlertor indicate a leak?

The LeakAlertor is able to detect intermittent leaks and alert the user during the flush, even if the toilet has temporarily stopped leaking. Generally speaking, once a toilet begins to leak intermittently (periodically), the flapper will continue to deteriorate until the leak becomes virtually continuous.

What causes my flapper to leak?

The primary reasons that a flapper might leak:

  • The flapper deteriorates over time due to cleaning solvents, repetitive use and/or hard water.

  • A small piece of foreign matter may be lodged under the flapper lip.

  • The flapper in your toilet may not be the correct make, model, or size.

What should I do if my toilet is leaking or if the flapper is stuck?

In most cases, the flapper should be replaced. Flappers are readily available in the plumbing aisle of your local hardware or home improvement store. You can also call your local plumber to replace it for you.

General Questions

Ask the Engineers

Is the LeakAlertor 6000 able to collect information?

No, this is not an option with the LeakAlertor 6000. The software operating the LeakAlertor 6000 is very dynamic. It performs a wide range of operations in order to monitor and analyze your toilet’s operation. The LeakAlertor 6000 is designed for use in homes and small businesses, and although it is able to process a large amount of data, the 6000 does not collect or store this information.

Our LeakAlertor Wireless PRO has the ability to wirelessly transmit data by text and email and create notifications on a cloud-based Dashboard. The Wireless LeakAlertor PRO is designed with property managers in mind. 


Can the LeakAlertor be put inside of the tank?

No. The LeakAlertor 6000 is designed so that the enclosure hangs outside the tank, with the sensors inside the tank (as shown in the installation video). Only the LeakAlertor Connected and LeakAlertor SmartStop are designed to be inside the toilet tank. 

Can I bend the sensors?

Yes, but do so gently. The sensors do not take a lot of effort to bend. When you are adjusting the sensors, hold them between your fingers where they enter the plastic tubing for support with one hand, while you adjust the sensors with your other hand. You may need to adjust/bend the sensors during your initial installation if they are touching each other, the tank sides, or parts inside the toilet. Once the unit is installed, you should not need to make any further adjustments.


Can I move the LeakAlertor to a different toilet?

Yes. Unlike previous versions of the LeakAlertor, the LeakAlertor 6000 can be easily moved from one toilet to another. Press the reset button on the LeakAlertor, remove the unit from the current toilet, and place it on the rim of the new toilet. Press the reset button again, it’s that simple.


Although you can transfer the LeakAlertor to different toilets, we recommend placing a LeakAlertor on each toilet in order to maximize the opportunity to detect leaks when they actually occur, as well as identifying wide-open flappers and imminent overflows.

The previous LeakAlertor would go off when I was in the shower or using a hairdryer. Will the new LeakAlertor do the same thing?

No. The LeakAlertor 5000 – the previous generation of LeakAlertor – was designed to detect and analyze water movement inside the toilet tank through translational vibration. This occurs when water moving inside of the tank causes the tank to vibrate slightly, which produces distinct sounds. Unfortunately, hair dryers, bathroom fans, running showers, etc., also produce a lot of sound, which could sometimes lead to a “false positive” indication on the 5000. The LeakAlertor 6000 works in a completely different way. The LeakAlertor 6000 operates by directly measuring the rate of change of the water in the toilet tank, so vibration and sound is never a problem.

How do I stop the LeakAlertor from beeping?

Press and hold the reset button until the red light comes on (solid, not blinking). If you’re working on the toilet we recommend removing the battery until your repairs are completed.

The sensors go into the water...can I receive a shock?

No. The LeakAlertor is completely safe to use and harmless.

Can the unit get wet? What happens if I accidently drop it in the toilet or in the tank?

The LeakAlertor has been designed so that it can be cleaned or even sprayed with water without affecting its operation. If the unit is accidentally dropped in the water, remove the top cover and remove the battery. Leave the unit and battery somewhere safe for 48 hours to allow time for the moisture to evaporate. After 48 hours, install the battery and put the top cover back on. The unit should power up normally and can now be placed back on the toilet.

Do not attempt to dry the unit off with a towel, paper towel, hair dryer, etc. Doing so may damage the product and void the warranty.
