No pressure cold bath tap
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.
