Default cold water supply - airlock?

I recently had an ensuite installed which consists of a power shower, sink
and loo. The hot water for the shower comes from the main hot wter tank,
whilst the cold for all 3 comes from the cold water tank in the loft.

Recently there has been no cold water supply i.e. the shower "struggles",

no
water out of the tap and the cistern fails to fill. I have managd to get a
tube with a cloth round the end for a seal to blow through the pipe in the
cold water tank feeding these, which forces water through to e..g the tap
and cistern ok suggesting no blockage but then the situation reverts to no
water.

any ideas gratefully received as to what might be causing this and any
solutions - the recent plumbing has been done with push fit connections

thanks
Cheers

The normal solution to this is to put a hose from a mains fed cold tap onto
the tap fed from the tank and open both taps. The mains tap is at a higher
pressure than the tank fed pipe. This blows any air back to the tank and
fills the pipe with water. It is usual to hear the most amazing gurgling.
It may also be a good idea to lower the level in the tank to prevent
overflow and have an assistant standing by in the loft or the mains tap,
just in case of an overflow starting.
