This morning I ave awoken to virtually no water in my taps. The Caleffi pressure gauge is at 4, but as soon as I turn on a tap is drops to 0. If I flush the toilet it takes around 30 minutes to refill. I have turned on the shower and there isn't any water. I noticed on Friday that the pressure was getting low, but I was away all weekend and there is now no water. I live in a block of reports and I haven't seen my neighbours to ask if they are experiencing problems. Does anyone have any ideas as I would like to get this resolved ASAP.
