Good to hear, things worked out well for you, hope you don't think we were being tough on you, but this is a good topic, for others to learn from.
"get it fixed but have the plumber bill the homeowner. You might split the costs."
I like my customers, and value them they are my golden egg, when i break it i pay for it.
"We've put it in our u/g work contracts that we're not responsible for lines that are not located."
In this part of the country, it's the contractor digging that is responsible for locating the lines, we call line mark for the utilities, and we check the rest of the property before any digging is started, If you read your contractors policy, underground work, has a lot of exclusions.
