  • Do I need an electrician? What about a plumber?

    No. The installation process is just like installing a regular pull-down faucet with an addition of one more component and a few easy-to-connect wires. Because the faucet works on batteries, there is no need to hire an electrician to assist with the installation. Even the batteries are included in the box. With DIAMOND™ Seal Technology, the integrated supply lines mean everything is included in the box.

  • How do I know if my Pilar faucet requires grounding?

    Grounding is not required on Pilar faucets manufactured after February, 2009.  If the solenoid does not have a green grounding wire (see image), it does not need to be grounded.

  • How do I know the “Touch” feature is “on”?

    A LED indicator light at the base of the faucet will shine blue when the “Touch” feature is activated. If the handle is in the “off” position, you may tap the spout or handle to turn off the light.

  • How does “Touch” actually work?

    Every person has a characteristic called capacitance. Capacitance is an electronic term that has units of measure called farads. Capacitors are electronic components that store electrical energy. A human body typically has 22 pico farads of capacitance. A result of this capacitance is often felt in the winter months via static discharges that occur when walking across a carpet and touching a metallic object. Walking across a carpet generates energy that is stored in the body’s capacitance. This energy is discharged when touching another object at a different voltage potential.

    A capacitive touch sensor is basically a sensing device that measures capacitance in its environment. When a touch sensor is connected to the faucet, it first establishes a baseline level of capacitance. Once this is established, it then looks for an increase in capacitance that occurs when a person touches the faucet (the human body’s 22 pico farads). The sensor detects the increase in capacitance and either turns on water flow or turns off water flow. When the person releases the faucet, the decrease in capacitance is also detected.

    Touches and grabs are distinguished by measuring the duration of the person touching the faucet. Touches are defined as being less than 300 milliseconds, and grabs as more than 300 milliseconds.

    There are two capacitive touch sensors in the Pilar® faucet with Touch20® Technology. The first touch sensor is connected to the handle and the second sensor is connected to the spout. If a touch sensor is connected to anything conductive (wire, metal sheet, metal bar, etc..) that conductive element becomes an extension of the touch sensor.

    In the case of the Pilar® faucet with Touch20® Technology, the first sensor is attached to the handle which is made of brass. Since brass is conductive, the entire handle of the Pilar® is a touch sensor. The second capacitive sensor of the Pilar® is connected to the spout. As the spout is also made of brass, the spout is also a touch sensor. However, depending on what is defined as the spout, there may be two exceptions:

    1) At the base of the spout is a black plastic insulating ring. It’s function is to isolate the spout from a sink. This black ring is not touch sensitive.
    2) The pull down wand is isolated from the spout via an insulator. Because of the isolation, the pull down wand is not touch sensitive. This arrangement is intentional to provide the most intuitive operation of the faucet.

  • I have a cross-flow of hot and cold water.

    If there’s a cross-flow of hot and cold water, it could be that the check valves are not properly installed on the supply lines.  Make sure the ferrules are screwed onto the check valves and that the hot and cold water lines each have a check valve installed.

  • Is it easy to install?

    Yes. The installation process is just like installing a regular pull-down faucet with an addition of one more component and a few easy-to-connect wires. With DIAMOND™ Seal Technology, the integrated supply lines mean everything is included in the box—even the batteries.

  • My faucet turns on and off by itself.

    If your faucet turns on and off by itself,

    1. The grounding clips may not be properly installed. Make sure they haven’t been bumped off with use and that they’re in the proper place and secured with tape. Also check for proper grounding. Grounding is not required on Pilar faucets manufactured after February, 2009.  If your faucet does not have a green ground wire, it may not require grounding.



    2. The spout may be in electrical contact with the sink. Make sure the spout insulating components are in place.
    3. Remember too that the faucet automatically shuts itself off after 4 minutes if there is no activity.

  • My handle or spout does not respond to touch

    If the handle or spout doesn’t respond to touch,

    1. Check the batteries.  Make sure the batteries are new and properly loaded in the battery box, and that power is available.
    2. Another possible cause is that the grounding clips are not connected. Make sure they’re properly installed as described in the Maintenance and Installation Guide, and that the faucet is grounded to an electrical or plumbing line. Grounding is not required on Pilar faucets manufactured after February, 2009.  If your faucet does not have a green ground wire, it may not require grounding. Check to be sure all electrical connections are solid.

    3. It is possible that the spout is in electrical contact with the sink. Make sure the spout insulating elements are in place and, again, check for proper grounding.
    4. The valve may simply not be turned on. Make sure the handle is in the ON position and that power is available.
    5. It could also be that the user is not touching the faucet properly. Make sure the touch is not too long or too short — it should be deliberate, like striking a key on a piano. Don’t use fingernails or a dry cloth to touch the faucet.
    6. Finally, the unit may need to reset. Disconnect the battery, wait 30 seconds, then reconnect the battery.

  • The LED does not come on

    If the LED does not come on, it may be there’s no power. Check the batteries.

  • Water & electricity…isn’t that bad?

    The faucet features DIAMOND™ Seal Technology, which has PEX waterways. This means that the waterways are lead free so once inside the faucet, water does not come into contact with metal contaminants nor any of the specialized “Touch” components, alleviating any electrical safety risks. Touch20® Technology operates on 6-Volt batteries and according to electrical safety codes, anything less than 24V is considered safe.

  • What are the safety features?

    When operating the faucet in “Touch” mode, an automatic shut-off feature will stop the flow of water after four minutes if the water is left running with no activity.

  • What if my cat/kid/etc turns it on?

    Touch20® Technology is a sophisticated technology that can detect the difference between a tap and grasp. However, should the faucet be activated accidentally, the automatic shut-off feature will stop the flow of water after four minutes if the water is left running with no activity.

  • What if there is a power outage?

    The Touch20® Technology is powered by four C batteries, therefore the “Touch” function will still operate during a power outage. Even without battery power, the faucet will operate with manual function

  • What if you grab it? Does will it continue to turn itself on/off?

    No. Touch20® Technology is a sophisticated technology that can distinguish the difference between a tap and grasp by measuring the duration of the contact with the faucet. Touches are defined as being less than 300 milliseconds, whereas grabs as more than 300 milliseconds.

  • What size batteries? How many? How long will they last? How do I know they need to be replaced? What if I don’t replace them in time?

    Touch20® Technology is powered by four C batteries. Ordinary batteries will last up to two years with standard use. The LED indicator light on the base of the faucet will start blinking red when it is time to change the batteries. If the batteries are not replaced in time, the faucet will still function with manual operation.

  • How do I control water flow/volume?

    You control water flow manually with the handle, just as you would operate any standard faucet. When operating the faucet in “Touch” mode, the water flow setting remains the same as the previous use.

  • How do I turn it off and on?

    There are two ways to turn the faucet on and off.

    • You may choose to operate the faucet as you would  any standard single-handle faucet by moving handle to the on and off positions.
    • Or, once the faucet has been turned on using the handle, simply touch the faucet to start or stop the flow of water.
