Customer called us out because he wanted an estimate to replace 2 hose bibs. I got there and saw the hose bibs in question. They were both in the backyard. They were both half inch and were screwed onto a nipple that screws into a tee, the tee is screwed onto another nipple but is so close to the wall that you can’t hold backup to prevent fittings in the wall from turning. This is likely the reason they were left there in the first place. If I do the work there is a chance something could go wrong inside the wall. I explained all this to the homeowner and he thanked me for my honesty and decided that he didn’t want to mess with them at this time.
