The removal of his equipment should be his own expense but if you work together in its removal, you could find a larger issue and fix something before you lose sewer/water service altogether. As always, an experienced attorney in your area can help discuss this at length.

If the plumber wants to pay to dig the area up to retrieve his shake I do not see a problem with that. If the tree root is that large then it can be removed when the snake is cleared. Make sure the plumber uses someone licensed and that your sewer lateral is restored to its original condition. Who knows, the excavation could discover a problem with your sewer lateral. Good luck.
