?Our house came with a Grohe kitchen faucet. I don't have the model number
but it's a single post-type faucet with controls and flex pipe for the wand
all in the same counter top opening. The problem is that it's loose and I
cannot figure out how to tighten it.
The part coming through the counter top seems to be nylon. There is a loose
rubber O-type ring that is half-way compressed with what appears to be a
piece of cast bronze with an open D shape. I cannot tell if the bronze
piece slides into a grove to wedge it down, screws on threads to compress
and hold the faucet in place or what it's supposed to do. When I try
turning the D shaped piece of bronze, the entire faucet rotates and it seem
solidly locked to the nylon piece.
Have you gone under the sink to see how it is fastened? A wise
person taught me years ago to install the faucet with the sink out on
a table-top or on the counter. That way you can get at everything,
and tighten the faucet properly. Once the faucet is tightened down,
then you mount the sink in the opening. One of the best pieces of
advice I have ever gotten. Even with the faucet wrenches that you can
buy, it is still much easier to tighten everything down while you can
get at things easily.....
Yes, I was under the sink this morning, with flashlight, looking for a way
to tighten it. I'd assumed that it was typical, with a threaded "nut" that
would cinch the faucet to the counter top. Instead, it was some strange
thing using the mentioned cast bronze "d"-shaped device. I don't know
whether to try turning it, or treating it like a wedge and squeezing it into
the fitting. That's where I'm hoping someone familiar with a H. Grohe
kitchen faucet installation can help.
In this particular kitchen, it is now virtually impossible to remove the
granite top to get to the faucet's underside, due to the length of the
Your advice is very well appreciated, however, since I "dry fit" most things
Not to bust your balls but this is the very first thing I saw when I did
a google search on Grohe faucets:
If you will select the faucet that most closely approximates yours, then
follow the links to More Details > Technical Product Information.
That's where it has its installation instructions along with exploded
Many thanks, Jay, for the excellent link. I can see the D-shaped piece in
the exploded view. It's probably my computer's resolution, but I can't see
how it's fastened in. The dimensional drawings suggest that the disk is
wedged in place with screws, similar to a disposal.
