How to drain cold water tank!?!

[Johnnorman40]

Help! I’ve turned off the gate valve that supplies my toilet white goods. Now it won’t open. It’s turning but water not flowing through. I need to drain the cold tank to replace the gate valve but the cold tank goes to a pump and I when I turn off the water, no cold water comes through the taps. Does any know how I drain the cold tank??

Might the pump only be for say, a shower and have you opened all taps in the property.

Figured it out!! Had to drain the tank via the cold tap in the bathroom. Took an age but sorted it all! Thanks!
