Many sites are isolating drinking fountains and taping up some basins to provide social distancing. This is appropriate from a COVID 19 management perspective but it unfortunately creates deadlegs in the water system and increases the risk from legionella.
If you are isolating the supply, these outlets require weekly flushing to prevent stagnant water from building up.
If outlets such as drinking fountains are unlikely to be used for many months they should consider removing them and all associated pipe work from supply or draining them
