Gurgle Tap Filter F38

Back to FAQs Gurgle Tap Filter F38

  1. What is the use of "shower mode"?

    It is another mode of waterflow, by which the water exit is dissipated, allowing wider radius of water stream.

  2. Can I use hot water for F38?

    Do not allow hot water to flow into the Gurgle. It will damage the membranes. It is fine for water that does not exceed 35ºC.

  3. During installation of the Gurgle Tap Filter, do I need to remove the filter cartridge first?

    Yes, by removing the filter cartridge, installation is easier due to less obstruction from the filter cartridge. When installing Gurgle, you should remove the current aerator cap presently on your current home tap, before affixing the washer and/or adaptors provided in the Gurgle package.

  4. When installing without an adaptor, I cannot get the Gurgle base unit tightened to the tap.

    Looking into the mounting collar, there is a Strainer provided (ie: rubberized ring with metal gauze). Remove this and replace with the Washer instead (ie: rubberized rings without any gauze). There are 2 sizes of washes that come provided in the package. Try out the larger Washer first (3mm thick) into mounting collar, and affix to your tap.

  5. The adaptor seems to be screwed too deep inside, so the mounting collar cannot be fully tightened against the adaptor.

    Remove the adaptor from the tap. On the top half of the adaptor to be fitted on the tap, wrap it with about 10-20 rounds of Teflon tape. Proceed to mount the Adaptor onto the tap, but screwing in only depth of about 2 threads.

  6. When switching between various modes, dripping is observed from the outlets under various modes : ‘PURE’, ‘TAP’ or ‘SHOWER’

    It could be signs that the Rubber-Ball Seal within the outlet had been dislodged, thus causing dripping. Follow the steps provided :

    1. Turn off the main tap and toggle lever of the unit.
    2. Turn on the main tap again. The flow should have regained and dripping halted.
    3. If problem persists, please call the local after sales service or local distributor for assistance.

  7. After installation, it looks like there is water leaking from under the Mounting Collar.

    For OUTER-Thread Taps (ie: taps with external tracks) :Your home tap's threadings should be pressing tight against the washer (ie: rubberized ring provided in the package), to provide a complete seal between the tap and the mounting collar. You will know the seal is complete when the mounting collar feels stiffly tightened.

    For INNER-Thread Taps (ie: taps with concealed tracks within) : Remove the Aerator cap currently present on your tap. Now for the Gurgle, place the Strainer (rubberized ring with gauze) or Washer (rubberized ring) into the Mounting collar.Next, using the appropriate Adaptor, place the relevant gasket onto the Adaptor. Wrap the thread that is to be screwed into tap with white tape. Go round the thread about 5 to 10 rounds at the top half of the adaptor that is to be mounted onto the tap.Using a coin (S$0.20 or S$0.50), insert firmly into slot of the Adaptor. Screw in the Adaptor into the Tap first. Once secured, proceed to mount the main body onto the Adaptor.

  8. When switching from ‘PURE” mode to ‘TAP’ Mode or from ‘PURE’ mode to ‘SHOWER’ mode, a distinct decrease in flow-rate is observed.

    The Rubber-Ball inside may have dislodged in-between switches. Follow the steps provided:

    1. Turn off the main tap and toggle lever of the unit.
    2. Switch to one desired mode.
    3. Turn on the main tap; the flow rate should have regained.
    4. If problem persists, please call the local after sales service or local distributor for assistance.

  9. Upon the first use, how do I flush the FC38 cartridge?

    To flush the Filter cartridge, please do the following:

    1. Mount the base unit to the tap (check for leakages).
    2. Fit the cartridge to the tap.
    3. Toggle the Lever and set the Mode to “Pure”.
    4. While pressing the Air Release Button, turn on the tap.
    5. Release the button only when the water starts flowing out from the button.
    6. Let the water run for 5 minutes prior to use.

  10. What is the purpose of the Air Release Button located at the top of the filter cartridge?

    The purpose is to release any air that may be trapped within the cartridge. When air is removed from the system, it prevents bacteria breeding, and thus extends the life of the cartridge.

  11. How do I know if the water pressure in my house is too high?

    Homes generally have a water pressure at ~2 bars, and flow rate is 4.5 LPM at tape mode and 2.5 LPM at pure mode. For certain countries, water flow rates are much higher, causing water pressure likely to be high too. Thus, Gurgle users are advised to cut down the water flow rates for reduced pressure.

  12. Why is it that Gurgle tap filters can block most viruses when most other brands cannot? What can it remove?

    Gurgle's filter cartridge is based on Hyflux's proprietary membrane technologies. With a membrane pore size of 0.015 micron, which is one of the finest among tap filters in the market, it can block off most of the viruses, which other tap filters cannot. Additionally, it removes 99.9999% of bacteria, reduces chlorine and bad taste/odours with its 3-stage filtration system. Water clarity is also improved (reducing turbidity), while retaining water's natural minerals beneficial to health. Easy to install, with no electrical power needed, it saves you the hassle and cost of boiling water for drinking. Being it provides instant drinking water on demand, you prevent bacterial breeding from stagnation with water stored in containers.

  13. How often do I need to change the filter cartridge?

    The filter cartridge on optimal performance has a capacity span of 1000 litres, which depending on level of usage, should last between 3 to 6 months.

  14. My family will be traveling for 1 week, do I need to take any precautions?

    When not using the Gurgle F38 for a period of more than 3 days, it is recommended that you remove the filter cartridge, keep it wrapped in a zip-lock bag in the refrigerator to prevent bacteria reproduction which is more susceptible in hot and humid countries.

    On storing used/wet cartridges, it is recommended that such cartridges be stored no longer than 14 days.

    Do not place the wet cartridge in the freezer or at very cold temperatures like zero degrees celsius. Reason is if ice is formed, it could damage the fine membranes within, or the cartridge could crack due to the extreme temperatures.
