Plumbing adventure

OK. A plumber I am not. I thought it would be an easy thing to replace the faucet under my bathroom sink after all, you just take a connection off here and then replace it there (of course after the water is shut off to the area). Well, I didn't take into account the old plumbing in my house. I took everything apart (with a bit of coaxing to some of the old parts). I reassembled it just as it was before... Oh did I mention that it took a hammer and chisel to remove the old one?!? I put everything back together in order... easy stuff right? WRONG! When I reconnected the hot water the old valve started to drip. I thought it may not be too bad until I can put some putty in the leaky spots... Wrong again! It started to drip, then drip a bit more and then just pour a small stream from there. SO, I though we will just go on to the cold water and come back to this part. Cold water connected fine... only a minor setback with a thread that didn't want to match up but eventually I convinced it. Looks good for the cold so I turn it on as far as it should go. No problems. Then a slow drip from the NEW lead line. Then more of a drip. I look at both connections. That is not the problem. They are both dry. It is the NEW lead line that has a hole in the tube!! Today I stopped at Lowe's and picked up a new lead line. However, when I got it home I discovered that what I picked up from the area that said "Faucet lines" was actually a toilet line. The connector is not the same. I called it a day and will try again tomorrow when I have a bit more patience. I told the family that if I tried to do much plumbing around here, they would soon discover I have a whole new vocabulary :) Well, tomorrow is another day...
