    Q:Is there any smartphone app I could download and change the water running duration?

    Answer This Question

    A:  No. You need to buy a 250 dollar remote

    by|Jan 17, 2022

      A:  Thank you for contacting Grohe Consumer Connections, there isn't an app you can use on your smartphone for this faucet. If you have any more questions or need assistance you can contact Grohe @ 1800-444-7643 Monday - Friday 7am-6pm ET

      by|Jan 17, 2022

        A:  The faucet is a basic plug-and-play device. I don't recall reading about any smart app in the instructions to change the duration of flow. That's probably because if you continue to hold your hands in the right location for the sensor to recognize them, the water will continue to flow

          A:  How long you have the problem issued. If it still under warranty you return and exchange a good. Leakage mainly cause by the valve seat area has dirt created or the sealing seat may be damaged. Since, manufacturer haven't release any repair program for fixing their problem . You may contact company for assistant. I'm not advise you do the repairing as it will void your warranty.

              Wonderful handsfree faucet
              [This review was collected as part of a promotion.] This has been an awesome product. The installation was a bit tricky as I had to deal with the battery pack also but after going through the instructions a couple times I finally figured it out. I works seamlessly when you put you hands under it. We have had no issues with the response time or the sensor which I was really worried about. The little switch on the side is nice for changing temperature but I'll be honest we don't change it much as most people in the house love the hands free part.

                good
                [This review was collected as part of a promotion.] Elegance for my guest bathroom and with the automatic ability it's more convenient for everyone. I like the chrome finish and the temperature lever. The flow rate is like all the other modern faucets and should help conseerve water.

                  Love but lacking
                  [This review was collected as part of a promotion.] The look of the faucet is sleek and beautiful. The downfalls are the directions describing how to change some of the programming and modes. We used the faucet in our main down stairs bathroom and had no issues performing the general install. This faucet does have a battery pack so curious to see how long that life lasts. While I do love the clean lines, I would like to see the technology modified where perhaps some additional function was placed on the temp control lever. This i feel would add to the ease of use. A lot of women get ready standing in front of the sink. Where we installed the faucet is in a pedestal sink. Setting hair dryers or straighteners on the small edge sometimes lets them slide into the sink and can trigger the water to turn on. Overall we are pleased with the look but would like to see some additional development put into functionality.

                    Good faucet with water saving features
                    [This review was collected as part of a promotion.] I used this faucet to replace an old one that was on a vintage lemon yellow porcelain bath sink from the 1960's. It works with power from a small battery under the sink. I do not know where or when the battery will need to be replaced. One thing I like is the operation of the automatic feature that cancels when your hands are removed from the area. This is far better than the faucets that come on when activated and stay on until activated again. Those can waste huge amounts of water. Installation was easy but I would like to see included a simple inexpensive plastic tool to use to tighten the mounting nut. Otherwise you may need a socket wrench with a long extension. The flow amount is minimal and there is no adjustment that I can see. However it may be possible to replace the aerator with a high flow version. You can adjust the temperature with a small valve on the right side of the faucet body.

                      May cause splashing depending on sink
                      [This review was collected as part of a promotion.] Very simple to install, no special tools needed. Should point down a bit more to prevent splashing. Overall design is great, easy to change water temp. For our install I would get again due to the splashing.

                        Touchless Faucet In Bathroom Sink Success
                        [This review was collected as part of a promotion.] Product was well packaged with individually wrapped/bagged components to protect the beautiful chrome finish. Included installation instructions were easy to understand. This was a replacement project and the actual installation time for the new Grohe unit was about 30 minutes. Removing the old faucet and cleaning the mounting area was the most time consuming part of the project. I found it useful to lay out all the components and to review the instructions a couple of times prior to starting the installation. I do suggest a second person (helper) firmly hold the faucet in position when tightening the retaining nut on the underside of the sink. The unit works perfectly and I can predict water savings as the faucet will not be left running when the user is not active at the sink. The ability to adjust water temperature is a real plus. This was a good product selection and I recommend it highly.

                          Great faucet for cleanliness and germ free washing
                          [This review was collected as part of a promotion.] This faucet was very easy to install. In fact I felt it was easier to install then most other faucets. It works very well as far as sensing your hands and if you need to turn off sensor for cleaning it's very easy to do. It's also easy to set temperature control. My only complaint is the spray of water sprays forward a bit and gets water all over front of sink. It could be my type of sink, it's oval. What I really like is not having to clean it every day, being touched is great!

                            Excellent quality, Contemporary design.
                            [This review was collected as part of a promotion.] Excellent facet, outstanding Euro-design, quality and manufacturing. Easy-to-install with all supplied inlet lines and metric-to-standard adaptors included. Automatic on-off features uses a small battery pack (supplied) that is easily installed with supplied hardware. We decided to install this facet in our guest bathroom, offing an impressive and easy way for guests to quickly activate the facet. Water temperature can be adjusted by a small lever on the side of the facet, however unless you have an instant-on water heater under the sink you'll likely not want to hold your hands under the facet (activating the infrared switch) to allow the hot water to flow to the facet from a remote water heater. Supplied with various self-cleaning programmable modes, likely best used if installed in a seldom used bathroom. If water conservation is a concern then the factory preset of "no cleaning cycle" will offer the most economical and efficient option. Gentle spray stays activated for a few seconds, well-suited for hand cleaning. Overall, an excellent and modern choice for an upscale and contemporary bathroom. Excellent quality, functionality, and ease of use made this a great choice for our bathroom!

                              [This review was collected as part of a promotion.] Touchless, elegant, and modern, what more could you ask for? After installing this, you will wonder how you managed all along to not have touchless. This product is very similar to the faucets you will find in high end restaurants or hotel rooms. Having the convenience of touchless is a new found must have moving forward!

It is a great addition to my bathroom. No more turning on handles which controls the amount of germs in the bathroom. Grandchildren and Great grand children are impressed. This is truly a water saver also. This would be a great addition for any home.
