GROHE31380DC0 Single-Handle Kitchen Faucet, SUPERSTEEL, H 21 1/4" x W 4 7/8" x D 9 1/4"

Great. Take out the restrictor and you get great flow/pressure. Looks great and works well

J'ai acheté un robinet neuf, mis ce qui m'a été livré était usagé, et même très usagé a en juger la quantité de calcaire incrusté sur le bout du robinet (voir photo). Très très décevant pour un achat de 800$ supposé être neuf !(sans parler de l'état général du reste et de la boite au moment de la livraison).

I am pretty fussy (okay very fussy if you ask my kids) about taps, faucets, shower heads, etc., but this one meets all my criteria. It really works well, the spray faucet works very well, and the bar is super handy for putting a dishcloth on it to dry, when we are not having company. I have had it over a year now, and no problems.

We have had the faucet for about 20 months. Now the faucet portion of the tap does not stay in either spray or flow. It is somewhere in-between and is accompanied by a loud buzzing sound. Grohe is sending a new faucet (although it is backordered and will take a minimum of 2 weeks), but it took over an hour on hold (I gave up the first time after 30 minutes after listening repeatedly about how important my call was)

It has a hefty, well-built feel to it. The ~9" reach feels a bit short, but the spray can hit every corner of the sink just fine. Going to the full-size faucet would likely solve the reach but the size would take over our kitchen window. The finish on the chrome looks good, nozzle and flow work well*, and the handle offers great adjustment.It took me 1.5 hours to uninstall the old faucet but less than 30 min to install, test, and clean up the new Grohe K7. The method of installation is well thought out and easy to access even behind a deep sink. It comes with 3/8" hoses that attach with a 16mm (5/8") wrench. The collar locks below the sink with a single "bolt", measuring at maybe 14mm. You will need a helper to balance the faucet while the collar is locked below the sink; a socket, extension, and ratchet preferably to secure the faucet; then a wrench to attach the supply lines to the shutoff.* Our faucet worked wonderfully for two days, installed as it came out of the box. On the third day, flow was half of where it should have been. After fiddling with the handle on and off a few times, flow slowly decreased to a mere trickle. Slowly pulling the handle out would increase water flow slightly, followed by a slight thunk and a decrease in water flow. Without the head installed, water still trickled from the hose. I located the water restrictor/check valve (part number 7 in the K7 parts diagram) and removed it. Success! Water flow is now stronger than it was even when first installed. Blowing out the valve produced some debris, but re-installing the valve brought water flow to a halt. With the valve out again, a swift bang on the white end of the restrictor separated the diaphragm. I was able to pick out a large amount of rubber debris from the blue/grey end of the restrictor. Snapped back together and reinstalled, flow is now back to the original flow.[UPDATE AFTER FOUR YEARS OF OWNERSHIP]I've dropped my rating down dramatically. The flow restrictors are a problem, as mentioned above. For the latter two years we've used ours without the flow restrictors because they get clogged rather quickly. Now it flows too much, but can be regulated with the main handle.The bigger problem is the continued failure of the spray heads. The flow/spray switch wears out prematurely after a year and a half of use. As it wears, it is unable to keep the head in spray mode fully without holding the button. Once worn, it oscillates between flow and spray while emitting an awful honking sound. One can hold the button to get spray, but it honks when the button is pressed, then again when it is released. We are on our second failed spray head- that's right, two spray heads with the exact same failure mode!
