But use the cheap digestives if you’re dunking (to be on the safe side).

“I live in Dublin 5 and have recently had the most disgusting water supply. It usually cuts off at night or goes very low pressure, but when it works its a very murky brown/green colour (above). We usually leave the tap running for about 10 mins before it goes clear again but still has a weird taste. My neighbours have all had the same problems. Only been like this for the last few weeks.”
