You can pull this whole faucet and examine the A ring (between the faucet body and sink top) and even reconnect the water lines (and handle with cartridge) while you have it out, and inspect the hot water tube where it connects to the cartridge seat.

When you removed the cartridge what did you see in the valve body where the seats would be?

I follow HK's logic, and this would be an out of the ordinary situation, but something you can ask Grohe about.

As you see I like videos for general instruction and insights. Watch a few.

Now, do you know how to remove that faucet w/o damaging under-counter tubing ? Do you still have the dedicated "Star Wrench" Grohe supplies with each new faucet ?

No I don't have the "Star Wrench" anymore. The faucet needs to be loosened from above counter, right?

I actually just tried pulling out the arm and it doesn't move. Is this part just pulled out? I just to need to use more force. Just don't want to damage any other part.

I didn't remove the cartridge just exposed it to see if there are visible leaks coming from it above counter. I didn't want to remove the cartridge because I was afraid I could damage another part that may cause another leak. I wanted to at least just isolate the real leak.

Turn Water Off

1. Unscrew the handle.
2. Remove the metal hose, undo water supplies
3. Pull out the arm ( spout )
4. Unscrew the threaded rod ( if you don't have the Star Wrench, use pliers or Cresent Wrench. The threads are very fine. It will take many turns to unscrew. Be patient. Keep turning, until you hear the "U" shape brass nut to fall down to the cabinet ). It is a very common problem. Now the faucet is loose, ready to be lifted from the counter )

Hope that helps / Let us know how you did

Milo

PS: FYI - I am enclosing an image of similar problem we have recently attended on behalf of Grohe / warranty call. Almost identical to yours. Cause: bad seal between sink and granite counter top. Water seeping through, dripping through faucet hole. Now you know why I was mentioning it before.

Awesome! Thanks for everyone's help! This will have to wait until the weekend as the family needs the kitchen working. Just need to continue draining my bucket under the counter. :-)

I would like to add: Newer Grohe faucets have water supplies screwed into the body via 1/4" IP threaded end. There is an O-ring behind the thread as well. These supplies are screwed in by hand, no tools. The "O" ring makes the seal. Once you take the faucet out, try to twist it CW ( tightening it ) to see if it needed to be screwed in. If it leaked from that connection - all you will need is a new "O" ring. Just twist the supply CCW, unscrew it and take it down to the store to buy new O-ring.

Let us know how you did

This guy is at least 10 years old. You think this o-ring set-up will be here? Anyway, I will watch out for this. Thanks again.

Home Depot or Loews has everything you may need.

I took out the faucet this afternoon and took some picture to show what is inside.

First picture shows the supply lines. I think they look clean.

Second picture shows the output line. You will notice that there is some green deposits around the base. Could this be the leak?

Third picture, I was trying to show the condition of the rest of the output line. Not sure if it is visible but it is visibly "dirtier" with deposits than the supply lines.

I also tried attaching the faucet back to the main supply and turn on the water. I did see the contraption (lime green color) close to the output line get wet. It looks like it's a ball valve. Is this normal?

Unfortunately, aside from the ball valve getting wet, I didn't see any drip despite waiting for at least 10 min. I ran out of time this afternoon so I had to stop at 10 min. I may try again tomorrow.

What is really weird to me is that if the leak is coming from the output, why does it stop when I switch off the hot water source? Shouldn't it continue leaking even with just the cold water on? I definitely did not detect any leaks in the supply pipes going into the main valve.

Here's the picture of the supply lines.

Here's the picture of the output line with the green deposits.


Lastly, the picture of the condition of the rest of the output line/pipe.

Call Grohe, as Mark said earlier, they owe you a new faucet.

[green_garden]

Call Grohe, as Mark said earlier, they owe you a new faucet.

No, that is not the hot water supply line with the green deposits. That is the line going to the flexible hose.

[Milo Dolezal]

The faucet is 10 years old. Sorry to say, but I doubt Grohe will replace it free of charge. I think it is time to upgrade your kitchen faucet with new one.

[green_garden]

I understand. Just wanted to see if it was a quick fix like a cartridge replacement. But it looks like it's a bigger problem.
