How it Works


The DripLet uses two easy-to-install devices that communicate temperature readings and automatically initiate dripping when freezing temperatures are detected.


Arctic Setting

The DripLet technology now offers an 'Arctic' setting to accommodate modern, energy-efficient homes designed to withstand extreme cold temperatures. This feature allows you to tailor the dripping technology's activation, ensuring it only functions when the outdoor temperature reaches extreme lows, thereby preventing unnecessary water drippage.

The Interior Device

  • Installed underneath a kitchen or secondary sink such as bathroom or mudroom

  • Connects to the hot and cold water lines and the drain line

  • Turns water dripping on and off automatically based on the exterior sensor’s temperature readings

  • Powered by electricity (with battery back up) or battery

  • Interior temperature reading backup


The Exterior Sensor

  • Installed outside within 80 feet of the interior device

  • Measures ambient temperatures

  • Communicates temperature readings every 15 minutes

  • Powered by battery


Easily install the devices and then set and forget. Your home is automatically protected.


What the experts say...

Let all faucets drip during extreme cold weather to prevent freezing of the water inside the pipe, and if freezing does occur, to relieve pressure buildup in the pipes between the ice blockage and the faucet.


Allow a slow drip from your faucets to reduce the buildup of pressure in the pipes. Even if the pipes freeze, the release pressure in the water system will reduce the likelihood of a rupture.


When the weather is very cold outside, let the cold water drip from the faucet served by exposed pipes. Running water through the pipe - even at a trickle - helps prevent pipes from freezing.


A trickle of hot and cold water might be all it takes to keep your pipes from freezing. Let warm water drip overnight, preferably from a faucet on an outside wall.

  • Why leave faucets dripping in cold weather?
    Leaving faucets dripping in cold weather can help prevent pipes from freezing and bursting. When water freezes, it expands and puts pressure on the walls of the pipe, which can cause it to crack or burst. Dripping a faucet allows for a constant flow of water that can help prevent water from freezing and reduces the pressure on the pipes.
  • How does running water keep pipes from freezing?
    When water is left to sit in pipes in freezing temperatures, it can freeze and expand. The expansion of the water increases the pressure within the pipe that ultimately causes the pipe to burst. The DripLet allows for a controlled flow of water that reduces the likelihood that the water within the pipes will freeze. In the event the water does freeze, the DripLet allows for the increased pressure to escape reducing the likelihood of a burst.
  • How does DripLet work?
    DripLet’s solution is very simple to use. It is based on the premise that while we all mean to drip our pipes, sometimes we aren’t around, we forget or we’re not sure what the best way to do so is. The DripLet magic is in the two DripLet devices. One device is installed inside the home under a sink, and the second device, the sensor, is installed outside to measure the ambient temperature. When freezing temperatures are a threat, the sensor communicates with the interior device to automatically turn on the dripping mechanism. Once temperatures are back to a non-threatening level, the interior device automatically turns the dripping off.
  • Why do I need an automatic faucet dripping solution?
    In freezing cold weather, water freezes and expands causing burst pipes. This is very costly for homeowners, not to mention the hassle of fixing and replacing pipes and the inconvenience involved. Even a crack as small as 1/8th of an inch can spew out more than 250 gallons of water per day, averaging $20,000 in costs. In 2022, State Farm paid more than $181 million for approximately 9,000 claims from frozen pipe damage. According to the Insurance Information Institute, 1 in 50 insured homes has a claim of property damage from water or freezing each year. DripLet's automated dripping solution helps ensure that your home is protected before there's a burst, whether you're home or away on vacation. DripLet's automatic solution will also stop dripping once it determines that freezing temperatures are no longer a threat. In other words, once DripLet is installed your home is efficiently protected all season long with or without your involvement.
  • Should I let hot water drip to prevent freezing?
    In the event there isn't hot water in the pipes due to power outage, gas outage or another reason, it's important to ensure the hot supply line doesn't burst either. We therefore recommend that both the hot and cold supply lines be connected to DripLet to prevent burst pipes.
  • Can DripLet run solely on batteries?
    Yes. Both devices, the interior and the exterior ones, can run on batteries. The interior device can run either on electricity (with a battery back-up) or on battery, and the exterior one is powered by a battery. We do recommend connecting the interior component to permanent power, when possible. The power usage is very minimal and the devices hibernate when they aren’t communicating. Batteries should be replaced once a year, before the start of the winter season.
  • Where should I install DripLet?
    The interior device should be mounted under the sink and we recommend installing at least one per floor of your home. The exterior device should be installed no more than 80 feet away from the interior one, preferably near a window and protected under a roof or an awning though it is weather-proof. One exterior device can connect to multiple interior devices. The exterior device is intended to ensure accurate temperature readings.
  • Is it difficult to install DripLet?
    DripLet can be easily installed by a plumber or a handy person about as quickly as installing a faucet. In a typical home, the DripLet is mounted to the a wall or inside a cabinet, under a sink. The DripLet is connected to both supply lines which can be connected by using two tees. The drain line for the DripLet should be connected to the sink drain line, below the height of the DripLet to ensure proper drainage. Ideally, there's a power outlet nearby to connect to as well.
  • How much water does DripLet drip?
    DripLet uses a water restrictor that limits the drip to two gallons per hour, when activated. The DripLet offers two protection modes: Standard- The DripLet activates when ambient temperatures are just above freezing. This mode is ideal for homes located in regions where freezing temperatures are intermittent. Arctic - The DripLet activates only when ambient temperatures are near zero degrees Fahrenheit. This mode is ideal for homes located in regions where freezing temperatures are constant during the winter months and the homes are built to withstand such temperatures.
  • What happens if the two devices can’t communicate?
    No worries - your home is still protected. The interior device also has a temperature sensor that kicks-in if it loses connection with the outdoor temperature sensor. In other words, the interior device on its own can protect a home. The exterior device is required to get more accurate temperature readings but it is not essential to protect the home.
  • How do I know when to replace the batteries on the devices?
    The device sounds an alarm when batteries need to be replaced. It also has a low battery light indicator. We recommend replacing the batteries once a year, before the winter season.
  • What makes DripLet stand out compared to other similar solutions?
    DripLet is the only automated pipe dripping solution that provides the complete preventive protection package. By turning dripping on and off automatically in the home, DripLet mitigates water damage. DripLet is easy to install, while allowing for continued use of water. It is the only solution with multiple temperature sensors and also offers a battery back up. Driplet is also more affordable and easier to install than the standard automatic shut-off valve.
  • What is the added water utility cost of using DripLet?
    Burst pipes and insurance claims can cost you tens of thousands! Installing a DripLet for automated dripping is a worthwhile investment. The DripLet device drips around 2 gallons of water per hour. Please see some example estimations below: Example 1: 2 DripLets in a home, Price of Water $0.02 / gallon Estimated water utility daily cost*: $1.92 Estimated water utility monthly cost*: $57.60 Example 2: 1 DripLet in a home, Price of Water $0.05 / gallon Estimated water utility daily cost*: $2.40 Estimated water utility monthly cost*: $72 Example 3: 3 DripLets in a home, Price of Water $0.015 / gallon Estimated water utility daily cost*: $2.16 Estimated water utility monthly cost*: $64.80 *The examples above assume a continuous drip. However, the DripLet only drips when freezing temperatures are a threat. If installed in an area where daytime temperatures rise above freezing, water utility costs will be lower.
