Town water. My parents have a well, and it has been a pain from day one. Their old well was fine, but the new one has issues with iron bacteria, and even with a chlorinator in place, there’s like a 50/50 chance when they come home from a trip that the bacteria will have made it’s way into the pipes. The amount of time that my parents have had to flush out their whole system is bonkers. Lesson learned: I’m not buying a house that doesn’t have town water
