Hi Can anyone help with this. I was changing the kitchen sink and taps, so I had to drain the cold water tank and turn off the mains. I have now turned the water back on and the cold water tank in the loft is full, the hot water taps/pressure is fine, but the cold tap in the bathroom is just dribbling out. I have not touched this tap other than draining the system.

Any ideas??

you probably have an air lock,get a hose connect it to the cold mains probably kit sink cold tap and connect other end to bath cold open both taps for 10 seconds and that will probably do it,good luck.
Hi Frank,

Thanks for the advice I tried it this morning and it worked first time.

Thanks again, JD
