Icon of a person with a question markHave you ever asked yourself…

  • Why did my water bill go up so much?
  • Why do I always have to jiggle the handle to get the water to stop?
  • Why does my toilet sound like it’s running (when I haven’t even flushed it)?
  • How much water will I waste if I didn’t install the new toilet parts correctly?
  • Should I use chemical cleaners or dye tablets in my toilet?

Icon of a LeakAlertor deviceWhat is the LeakAlertor 6000?

The LeakAlertor is a smart device that electronically monitors your toilets for leaks, imminent overflows, and other water wasting problems.  The LeakAlertor identifies the faulty part then  alerts you both visually and audibly to toilet overflows, leaking flappers, or stuck wide-open flapper/flush valves BEFORE YOU LEAVE THE BATHROOM.

Water Loss Rate
Billing Unit Type
Per Unit Cost

Water Loss Rate options are: Low (2 GPM), Average(3GPM), or High. These rates are based on a water pressure of 60 PSI, and allow for the variances in tank size, fill valve operation, and supply line size. GPM=Gallons per Minute.

Choose HCF (Hundred Cubic Feet), 1000 G, or 100 G. The billable unit is located on your water bill. If you’re unsure which billable unit is used by your agency, we recommend selecting HCF. The majority of water agencies in the United States use one of these three billing units. 1 HCF = 748 gallons of water. 1000 G = 1,000 gallons of water. 100 G = 100 gallons of water. The total number of gallons used during the billing period (typically one month or about 30 days) is divided by the billing unit measurement (HCF or 1000 G) then rounded down to the nearest whole unit to determine the number of billing units charged. For example; if 10,000 gallons of water were used during the billing period, this would equal (13) HCF billable units, (10) 1000 G, or (10) 100 G billable units.

Enter the amount of your combined water and wastewater usage charge per billable unit. This is located on your water bill. (if you receive separate water and wastewater bills, combine the usage charges from the two agencies). If you don’t have your water bill handy you can select from the National Average cost, or use choose from one of the cities closest to you from the drop down menu.

How does the LeakAlertor 6000 work?

The rise and fall of water inside the tank is the heartbeat of a toilet. The rate at which the water rises and falls, under varying conditions, determines the health of the toilet. The LeakAlertor is a diagnostic tool used to monitor your toilet’s health. In the simplest terms, the LeakAlertor uses complex mathematical functions to determine when these changes in water height indicate a toilet leak, wide-open flapper, or imminent overflow on any tank-based toilet. The LeakAlertor then alerts users with simple flashes and beeps.

Wide-Open Flapper


Leaking Toilets

What is a “Phantom Flush”?

Have you ever heard your toilet periodically make a noise that sounds like the water is running, but it hasn’t been flushed recently? What you’re hearing is called a phantom flush, the unintended and unseen escape of water from a toilet that is not operating correctly.

A phantom flush occurs when water leaks from the tank into the bowl due to a faulty flapper (or another similar failure). As the water level inside the tank goes down, the float drops. This opens the fill valve briefly, allowing it to refill the partially empty tank.

If the failure causing the phantom flush is not corrected, a repetitive cycle of leak…fill…leak…fill is created. This cycle can waste 50 – 200 gallons of water every day, making leaking toilets the #1 cause of unintended water use in the home.


What causes a “Phantom Flush”?

Below is a list of reasons why the repetitive “Phantom Flush” cycle can occur.

  • Flapper is not sealing properly because:
    • It’s the wrong size or model for your toilet.
    • Something is stuck under the flapper lip.
    • It has deteriorated or warped from hard water and/or cleaning solvents.
    • It is physically defective.
    • It has a pinhole in it.
  • The chain is not working properly because:
    • It’s too short and holds the flapper open slightly
    • It’s too long and gets stuck under the flapper
    • It gets kinked and holds the flapper open
  • The fill valve stops working correctly (leaks or doesn’t fully close)
  • The float height is set improperly
  • Fluctuations in water pressure throughout the day
