problems with kitchen monoblock

[Martin phillips]

Good evening,

Please can anybody help, I have replaced a sticky cold side of a kitchen monoblock with a new reviver. There was nothing wrong at all on the hot side. Having replaced the cold with no problems no more sticking.i turned on the taps the cold runs no problem but the hot nothing, but I have not touched the hot very confusing any thoughts would be very helpful thank you.

Did you isolate the hot side and haven’t turned it back on??
Is there some debris from the old cold valve which has been pushed through to the hot side?
Wrong depth cold valve??
Got any pics?
