Sticky Tap

[taycast]

I have a sticky tap which is difficult to turn on and off. Its downstairs with my mains pressure hot tank on the first floor.

I want to check what I need to do to have a look at the tap.

Should there be a stop cock to shut off hot water between tank and all taps near the tank? If so, when I close this, I assume I then run the tap I am fixing until it goes dry, carry out my repair then open the stop cock upstairs again? Will doing it this way empty all the hot water pipes between stop cock and tap to be fixed?

Is there anything I have missed? Can sticking taps usually be fixed or do they usually need replaced. Cheers.

Have you checked to see if there's an isolating valve locally to the tap?

If there isn't, then just shut off the cold supply to the pressurised cylinder.

Taps can always be serviced as long as they haven't been left dripping/trickling for a long time, which wears the seat beyond the point of recovery.
