I am the Kat that Walks By Itself

Lucky you looked out! They really should have warned you. Here, they put a leaflet in the letterbox if they're doing maintenance, and a couple of weeks ago when they did an emergency fix, they did knock on doors first to warn us the water would be off for an hour or so--and even cam back after wards and told ue to turn on the lowest tap to clear the air. That almost made up for having no water last month when a pump suddenly failed.
