Dear Ruth,
My building has had a spate of leaking/spurting water pipes in the last couple of weeks, causing significant damage and (obviously) expense. The trustees are looking into what can be a cause, and one hypothesis is the very hard Cambridge water causing corrosion. I have lived in Cambridge for 50 some years, and I do not think this can be the cause if no other buildings are suffering the same problem. As you are in touch with so many people, do you know if any of the other bigger buildings (ours has 20 units) have had trouble with pipes failing? I will also reach out to a city councilor to ask.
Thank you.
Ann
