I have replaced ith a new mixer tap so its is a bit hard to connect a hose
pipe between them..


Try blowing back up the spout with the tap full on to see if it clears. One
thing I'd ask you to check to see is that no debris has fallen into the pipe
work when it lay open or that any PTFE Tape you've applied to the joints
hasn't pulled over the ends of the fittings or the pipes.
