I'm replacing our kitchen sink. It has a Grohe Lady Lux faucet that I'd like to reuse.

Can anyone tell me how to get it out of the sink?

From what I can see (the sink is out) there's a horse shoe shaped nut on the bottom but turning it will damage the supply lines coming from the faucet.

Thanks,

Al Sharff

You don't have to do anything under the sink. All can the hard work can be done from above:

1. Pull out hand spray as much out of the rigid goose neck as possible
2. Pull on the rigid goose neck. It will pull out
3. You will expose and see brass-like-nut on top of the column
4. Take crescent wrench and unscrew it. It has fine thread so it will take many turns to unscrew it. Eventually you will hear the U-shaped washer to drop down under the sink.

Of course, if you access, it can be unscrewed from the bottom, too. . Remove water supply lines, hose. There is an deep nut. Take crescent wrench and unscrew. That "horse shoe nut" is really a washer, not a nut. It slips over long threaded brass bolt and around water supplies, and holds faucet against counter top.

Sorry, I tried to locate exploded view of this faucet that shows with removed spout exposing the brass nut - but could not find one...

Thanks for your help. I needed to tighten my faucet and did not know how to remove spout. It simply pulls off and I was able to tighten faucet with a wrench from above.

Exactly. Grohe makes this part of installation very easy, doesn't it. No crawling under the sink and working with tools in tight spaces. :D

Thanks so much! This information was very helpful... my husband isn't too good with his hands and normally we have to pay a plumber but you made it so easy that he actually did it hisself!
Thanks Again for your help!!

Replacing the sprayer house should be a 20 minute job max if you use the quick release that is connected to the spray hose under your sink. If you release the sprayer hose using the quick release in the picture below, then you can easily get to the end of the hose and remove it from the quick release and pull the house through from the top.

I spent about an hour looking at the horse shoe nut from the bottom of the sink trying to figure out how to remove it. After reading your post, it was a breeze. Thanks! Of course, I waited until Christmas eve to try this, so this was a real life saver. I guess it always pay to do your homework first, before tackling a job.

biljeemike: LOL ! Good to know you were able to fix it after all. Happy Holidays to you ! Milo

Wow... thanks for the great advice! I too spent an hour trying to figure out how to remove the horse shoe shaped nut and then went to Home Depot to look for a special tool. One of the store associates was kind enough to look up Grohe tool on his computer in the store and I just happened to see the question "how do I remove a Grohe kitchen faucet" and asked him to go back. I saw your answer and couldn't believe it... I would have never figured it out.

Had it installed in about 40 minutes (I'm slow)... thanks again!

I was trying to tighten mine form the top, but the nut is so tight that the wrench just slips. (Using an adjustable wrench, but fully tightened). The flat sides "indentation") of the nut are slight, so I guess the wren is able to skip against the soft rounded brass at the edge of the flat side.

As much as I don't like this advice, you can always try using a pair of water pump pliers to grab the metal and unspin the connection. If you hold firm, it should NOT harm the faucet in any way, but it should get it started turning...;)

I assume that's the generic name for Channel Lock pliers. Tried it. Might be losing my grip, or that's one stubborn nut. (My wife calls me that all the time, maybe it's just payback.)

massplumber2008 · May 23, 2014, 03:45 PM

You could purchase a cheap plumber's wrench (grip won't be issue with that tool)...try that!! Back to you...

Do you mean a standard US pipe wrench or one of these Plumber wrench - Wikipedia, the free encyclopedia

FYI: There is a brass nut under the sink on long threaded faucet column. It secures faucet to the counter top. If there is enough space, you can take basin wrench and help it from down underneath. Once it gets loose, finish unscrewing it from the top. Hope that helps. Milo

Thank you, massplumber2008, that worked.

The advice given by another to use the plumber's wrench under the sink does not work too well. The Grohe unique mounting/fastening system doesn't work well without their special tool.

To go under the sink, you need a special tool. Above, the plumber's wrench... or even a tight-fitting standard wrench, will do the job.That sucka was really tight!
