No cold water from 3 upstairs taps since returning from holiday.

[DomC]

Cold water storage tank in loft. Always had a cold basin tap in the en-suite that has not worked, but haven't bothered with it; but since coming back from 2 weeks away, i have 3 upstairs taps that have also given up the ghost.

Have tried blowing down the pipe from inside the CWST but no change.

Any idea please ?

Try finding someone with a wet vacuum you can borrow and give them a suck out.
