They bought pensions not flush valves or faucets

they found that few of the sinks or toilets were functioning and the cafeteria was flooded.

Sounds like the valves on the water supply are working OK?
The waste and drains, not so much.

My guess, they swept EVERYTHING they could down open pipes, then installed new fixtures.

My hundred year old house had plaster dumped down the vent stack, small wonder the drains were slow.
