I took a break from some computer work 3 months ago and decided to fix a slow leak from my kitchen faucet. Cap on cold water valve had trouble gripping when replaced so I added teflon tape to tighten it up. I started doing my dishes in the sink and the thing blew clean off (90lb pressure here!) and I was OMG what do I do? Hand on faucet top to stop the 5 foot geyser. Tied a sponge on the top with a giant plastic bag at hand, turned off water to the house, bought new faucet at local HW store, couldn't install it because the nipple out the wall had deteriorated (galvanized and super old). Bought die to try to repair threads on nipple, no soap. Bought diamond hole saws so I could recess the die into the wall enough to get the nipple to accept the new faucet, still no soap. Called plumber friend (just retired) who came over and we couldn't get the old nipple out the wall with internal pipe wrench.
Finally went to Yelp and got plumbers calling me left and right, a couple came over next day, the second one removed the nipple with a better internal pipe wrench, then went after the cold water one and it was even worse. All this time I'd had cold water but now I would have none until both nipples were replaced. I had to accept his $350 offer, had him install my water pressure valve for another $350. He was out the door with my $700 after being here for 2 hours and 10 minutes!
