Hi there I moved into my house about 2 years ago and I changed my bath taps so I had to drain down the cold tank in the loft.When I turned the water back on and refilled the tank there was no pressure out the cold tap it was just trickling.Not long after I had a plumber fit a pump in the ensuite so I could have a power shower and when he'd turned the water back on the tap in the bathroom had returned to normal pressure and its been fine eversince until yesterday I had to drain down the tank for another reason and when I turned the water back on and refilled the tank the cold bathroom tap has got no pressure again.Am I doing something wrong when I'm refilling the tank?any suggestions? Thanks.

Open up the bath tap and clean the ninlets. Now turn the water back on to flush out the cold water supply. Good luck, Tom
