Water system air lock?

We have just been getting our caravan ready for the new season. Whilst cleaning and flushing the water system we couldn't get water to flow in more than a trickle from the washroom tap on either hot or cold. The kitchen tap and shower fitting run well so
it isn't a pump issue. The hot water tank would not even fill properly despite the other taps running free. Tried three times to clear it by draining the system down and starting again but still no change. There wasn't the typical burbling noise of trapped
air but could it be an air lock. If anyone has any ideas about what to try next it would be appreciated.
