Hi again all,

I've identified the faucet as a Grohe (how do you pronounce that ??) model
31771 or 31735. Thanks to Casino Knight for identifying the brand. Reed, thanks
for the exploded view, but that's a bathroom faucet. Jeff, you're right, the
fluted part is a wobble preventer. The nut is an odd size. 11/16 is slightly too
big, 5/8 is too small, 17mm is too big, and 16mm is too small.

Given that Grohe is a european brand, I'd expect that 17 mm would be the
correct size, and it's about twenty thou smaller than 11/16".

I have no reason to expect that it'd be a LH thread.

If a 17 mm deep socket and a cheater handle won't start it, you could
always try using the "chisel technique".

Take a hammer and a flat cold chisel (with about 3/8" wide cutting edge)
and use them to make an indentation on one of the hex flats, about 1/4
of the way from the end of that flat, on the LEFT side of top center.

After you've made a groove, place the chisel tip in it and tilt the
chisel to the right. Strike it sharply and the combination of the shock
plus the offset force should start the part unscrewing.

That one's worked for me many times, especially where I didn't have the
correct size socket at hand and the part had to be unscrewed "raaht now".

HTH,

Jeff

I've been trying
with the 11/16 wrench, but it won't budge. I have a few pipe wrenches that are
longer than the 11/16 wrench--I'll give them a try. The problem is that I don't
know if they are a regular or backwards thread. I don't want to push too hard
and either strip or snap the housing. I've flooded it with PB Blaster for the
last 2 days with no success. I guess that Grohe is not a popular brand, and
nobody has any info on them--I've never heard of the brand before. Has anyone
ever seen backwards threaded cartridges before ???
