yeah, when installing the RODI yesterday I twisted the copper lines to the faucet, so the faucet needed to be removed and replaced, the rusty bolt was the one holding the faucet to the sink
there's no way I could fit anything large up there, so like I said I beat the crap out of it all until it broke through and I got it out and installed the new faucet
now IM going to go with hose hook in the bathroom for the RODI and not do any under sink install
