Today I found a slow leak in my kitchen faucet. It’s a pull-down style faucet with small copper tubing going through the counter, and the leak is where that copper meets the braided supply line. I don’t see any way to put a wrench on the copper pipe, so how can I fix this? I’m not sure, but it seems like maybe this fitting is meant to be permanent from the factory?
I don’t know the brand of faucet. The stem is a square, and I took photos of some identifying marks. If anyone can identify this, that would be helpful if I need to order a part.
