Hey guys, I have this bathroom faucet, the Kohler Fairfax Centerstand, not sure this is the precise model but this is it (https://www.us.kohler.com/us/fairfax-centerset-bathroom-sink-faucet-with-lever-handles/productDetail/sink-faucets/422218.htm). The hot water supply line burst, Kohler sent me a replacement hose but on the faucet side I am dealing with rounded hex so am having a hell of a time unscrewing this hose. I have tried channel lock pliers, monkey wrenches, vice grips... on the verge of losing my mind. Since the hose has a threaded post above the hex part I haven’t bothered trying to cut the bolt part since that would just still leave the threaded rod piece. I have called a real plumber, but they are all booked up for the next two weeks.

Since it’s not coming out should I just start tearing it apart with the cutting wheel on my Dremel or try something else. Replace the faucet?

It is brass. I have not tried a basin wrench. Don’t have one but would be open to getting one if you thought it might do the trick.

I’d use visegrips and lock them on tight.

If that didn’t work then kohler would be sending me a new faucet.

Kohler has a bad habit of putting things together at high torque.

A left hand thread ?
The way he has the faucet pulled up it appears he’s working on it from the top standing in front of the faucet..

If this is the case then turning the connection clockwise would unscrew it.

Same as standing over a faucet and unscrew ring the aerator, you turn it clockwise to remove it.

Looking at the tool marks on the brass hex, it looks like he’s turning counterclockwise which would tighten it.

What I would use on something like that would be 410 Channellocks, they are better than a pipe wrench on small fittings. a vice grip sqeezes the fitting flat, making it really hard to get apart.

I would use a crescent type wrench or open end wrench, no squeezing just rotation.
If I felt it rounding over, then for sure switch to the open end wrench, maybe after some penetrating oil.

I don’t know. Thinking I am F’d here. Tried clockwise/counterclockwise. Might contact Kohler like Twowaxhack mentioned, maybe just replacing the entire faucet makes sense. I just replaced my kitchen faucet last month no problem and didn’t run into anything close to this. Kind of defeated here. Feels like I could probably knaw the thing off with my teeth at this point. It just doesn’t want to budge.
