Airlock preventing toilet cistern filling

Hi there

We recently had a mains leak leading to no water supply for a couple of days. Following that there was air in the water system but the air passed through the hot and cold water taps and showers when they were turned on. We have two toilet cisterns that are not filling up, one on the first floor and one on the second floor. As this occurred immediately after the water was cut off, my bet is there are airlocks. If it is relevant we have a water pump on the ground floor.

My plan is to connect a hose to the kitchen tap or outside tap and also to the toilet inflow pipe and use the pressure to force the air through - hoping that one and two storeys height difference leaves enough pressure. Is this the right plan? Is there a better idea?

Have you cold water at the basins in the toilets
Either open pipe in hot press at valve and clear it there or as you propose could clear it

Thanks for the answer. We're a fairly new build so the on-site plumber came and cleared the airlocks around each toilet for 20 quid.
