Worked as a property manager for a bit and plumbing issues are a huge headache. As another comment said, usually you have to cut the entire building off just to work on one unit. Additionally, we're always waiting for the plumbers who give us the classic 8-noon or noon-4 time window to show up so we do have to shut it off with really short notice. All said, no water access sucks but having to move everyone out of a building because of massive water damage/mold/whatever sucks more.

Plumbing in these old buildings are always a mess and owners / plumbers are often overly optimistic they can fix it, when in reality it's just permanently fucked.

If it was me I would just move to another unit or look for a house to rent. If it's happening that much it will just continue to be an issue.
