Hi there,when i moved into my house a couple of years i changed the bath taps so i had to drain down the tank in the loft.When i turned the water back on and the tank refilled there was no pressure coming through just the cold tap.Not long after that i had a pump fitted in the ensuite to have a power shower and the plumber connected his hep to the feed to the bathroom cold tap and after he turned the water back on and the tank refilled the pressure in the bathroom cold water tap returned to normal.Yesterday i had to drain down the tank for another reason and when it refilled there is no pressure again in the bathroom cold tap.Am i doing something wrong when i'm refilling the tank?Any suggestions?
