My problem is different - been in the house 7 years, and about a year ago our kitchen faucet just stopped wanting to swivel. I've taken it apart, greased it, and reinstalled it including tightening the nut under the countertop as best I could. That helped for about two weeks. Now, it's basically bound up, fortunately on the correct side of the sink. Everything else works fine, but it is a cheaper builder's grade model so I'm thinking of replacing it.
I'd have no problem doing the install myself, except the dang faucet wrench that I have won't fit in the tiny little space where the nut is under the counter. Trying to find a good solution, perhaps some kind of extension... I hate paying plumbers for stuff I should be able to do... perhaps that'll change when I'm no longer in the accumulation phase and need things on which to "blow that dough!"
